ICD-10-CM/PCS Guideline Updates FY 2017 CHAR GORE, M.Ed, RHIA, CCS CM Guideline Updates Updates to Section I.A Conventions I.A.12.a Excludes1

I.A.13 Etiology/manifestation convention (code first, use additional code and in diseases classified elsewhere notes I.A.15 With I.A.19 Code assignment and clinical criteria (new guideline) Excludes 1 I.A.12.a - guideline updated Prior to 2017 only said: A type 1 Excludes note is a pure excludes note. It means NOT CODED HERE! An Excludes 1 note indicates that the code excluded should never be used at the same time as the code above the Excludes 1 note. An Excludes 1 is used when

two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. Added 2017 An Exception to the Excludes1 definition is the circumstance when the two conditions are unrelated to each other. If it is not clear whether the two conditions involving the Excludes1 note are related or not, query the provider. Excludes 1 Example Excludes1 Example

Etiology/Manifestation Convention I.A.13 guideline updated Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD10-CM has a coding convention that requires the underlying condition be sequenced first, IF APPLICABLE followed by the manifestation. Wherever such a combination exists, there is a use additional code note at the etiology code, and a code first note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. Etiology/Manifestation Example

With I.A.15 guideline updated The word with should be interpreted to mean associated with or due to when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular list. The classification presumes a causal relationship between the two conditions linked by these terms n the Alphabetic Index or Tabular List. These conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clear states the conditions are unrelated. For conditions not specifically linked by these relational terms in the classification, provider documentation must link the

condition in order to code them as related The word with in the Alphabetic Index is sequenced immediately following the main term, not in alphabetical order. With Example Code Assignment and Clinical Criteria I.A.19 - new guideline added The assignment of a diagnosis code is based on the provider's diagnostic

statement that the condition exists. The providers statement that the patient has a particular condition is sufficient. Code assignment is not based on clinical criteria used by the provider to establish the diagnosis. Updates to Section I.B General Coding Guidelines I.B.13 Laterality I.B.14 Documentation for BMI, depth of non-pressure ulcers, pressure ulcer stages, Coma scale, and NIH Stroke Scale I.B.16 Documentation of Complications of Care

Laterality I.B.13 updated guideline Some ICD-10-CM codes indicate laterality, specifying whether the condition occurs on the left, right, or is bilateral. If no bilateral code is provided and the condition is bilateral, assign separate codes for both the left and right side. If the side is not identified in the medical record assign the code for the unspecified side. When a patient has a bilateral condition and each side is treated during separate encounters, assign the bilateral code (as the condition still exists on both sides), including for the encounter to treat the first side. For the second encounter for treatment after one side has previously been treated and the condition no longer exists on that side, assign the appropriate unilateral code for the side where the condition

still exists (e.g., cataract surgery performed on each eye in separate encounters). The bilateral code would not be assigned for the subsequent encounter, as the patient no longer has the condition in the previously-treated site. If the treatment on the first side did not completely resolve the condition, then the bilateral code would still be appropriate. Laterality Examples If a patient has a condition that is bilateral but only one side is being treated you still code as a bilateral condition Example: Patient has bilateral senile, cortical cataracts and is here for surgery to the

right eye Code as bilateral senile cortical cataracts H25.013 If a patient has a condition that was at one time bilateral but has had surgery to treat one side and is now here to treat the other side then code as a unilateral condition Example: Patient had bilateral senile cortical cataracts the right eye was successfully treated last year they are here for treatment of the left side. Code as left side senile cortical cataract only H25.012 Code for right side cataract extraction status Z98.41 Laterality Examples continued..

When no code for laterality exists, code default code: If a patient has bilateral cataracts with no further specification and they are having surgery o the right eye, use H26.9 unspecified cataract If a patient had bilateral cataracts at one time but has had surgery to successfully treat the right eye and are now here to treat the left eye Code H26.9 for left eye Code Z98.41 to show right side cataract extraction Documentation for BMI, Depth of Non-Pressure ulcers, Pressure Ulcer Stages, Coma Scale, and NIH Stroke Scale I.B.14 guideline updated

For the Body Mass Index (BMI), depth of non-pressure chronic ulcers, pressure ulcer stage, coma scale, and NIH stroke scale (NIHSS) codes, code assignment may be based on medical record documentation from clinicians who are not the patients provider (i.e. physician or other qualified healthcare practitioner legally accountable for establishing the patients diagnosis), since this information is typically documented by other clinicians involved in the care of the patient (e.g., a dietician often documents the BMI, a nurse often documents the pressure ulcer stages, and an emergency medical technician often documents the coma scale.) However the associated diagnosis (such as overweight, obesity, acute stroke, or pressure ulcer) must be documented by the patients provider. If there is conflicting medical record documentation, either from the same clinician or different clinicians, the patients attending provider should be queried for clarification. The BMI, coma scale, and NIHSS codes should only be reported as a secondary diagnosis. As with

all other secondary diagnosis codes, the BMI codes should only be assigned when they meet the definition of reportable additional diagnosis. Documentation of Complications of Care I.B.16 updated guideline Code assignment is based on the providers documentation of the relationship between the condition and the care or procedure, unless otherwise instructed by the classification. The guideline extends to any complications of care, regardless of the chapter the code is located in. It is important to note that not all conditions that occur during or following medical care or surgery are

classified as complications. There must be a cause-and-effect relationship between the care provided and the condition, and an indication in the documentation that it is a complication. Query the provider for clarification, if the complication is not clearly documented.

I.C.21.c.11 Encounters for Obstetrical and reproductive services Zika Virus Infections I.C.1.f.1 new guideline Code only confirmed cases Code only a confirmed diagnosis of Zika virus (A92.5, Zika virus disease) as documented by the provider. This is an exception to the hospital inpatient guideline Section II, H. In this context, confirmation does not require documentation of the type of test performed; the physicians diagnostic statement that the condition is confirmed is sufficient. This code should be assigned regardless of the stated mode of transmission.

If the provider documents suspected, possible or probable Zika, do not assign code A92.5. Assign a code(s) explaining the reason for encounter (such as fever rash, or joint pain) or Z20.828, Contact with the (suspected) exposure to other viral communicable diseases. Diabetes mellitus and the use of insulin and oral hypoglycemic I.C.4.a.3 updated guideline If the documentation in a medical record does not indicate the type of diabetes but does indicate that the patient uses insulin, code E11, Type 2 diabetes mellitus, should be assigned. Code Z79.4, Long-term

(current) use of insulin, or Z79.84, Long-term (current) use of oral hypoglycemic drugs, should also be assigned to indicate that the patient uses insulin or hypoglycemic drugs. Code Z79.4 should not be assigned if insulin is given temporarily to bring a type 2 patients blood sugar under control during an encounter. Secondary diabetes mellitus and the use of insulin or hypoglycemic drugs I.C.4.a.6.a updated guideline For patients who routine use insulin or hypoglycemic drugs, code Z79.4, Long-term (current) use of inulin, or Z79.84, Long term

(current) use of oral hypoglycemic drugs should also be assigned. Code Z79.4 should not be assigned if insulin is given temporarily to bring a patients blood sugar under control during an encounter. Hypertension I.C.9.a MAJOR CHANGE A new general instruction has been added direction under the hypertension heading: The classification presumes a causal relationship between hypertension and heart involvement and between hypertension and kidney involvement, as the two conditions are linked by the term with in the Alphabetic Index. These

conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clearly states the conditions unrelated. For hypertension and conditions not specifically linked by relational terms such as with, associated with or due to in the classification, provider documentation must link the condition in order to code them as related. Hypertension Hypertension with Heart Disease I.C.9.a.1 guideline updated

Hypertension with heart conditions classified to I50.- or I51.4-I51.9, are assigned to a code from category I11, Hypertensive heart disease. Use an additional code from category I50, Heart failure, to identify the type of heart failure in those patients with heart failure. The same heart conditions (I50.-, I51.4-I51.9) with hypertension are coded separately if the provider has specifically documented a different cause. Sequence according to the circumstances of the admission/encounter. Hypertensive Chronic Kidney Disease I.C.9.a.2 guideline updated

Assign codes from category I12, Hypertensive chronic kidney disease, when both hypertension and a condition classifiable to category N18, Chronic kidney disease (CKD), are present. Unlike hypertension with heart disease, ICD-10-CM presumes a cause-andeffect relationship and classifies chronic kidney disease with hypertension as hypertensive chronic kidney disease. CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease. See Section I.C.14. Chronic kidney disease. If a patient has hypertensive chronic kidney disease and acute renal failure, an additional code for the acute renal failure is required.

Hypertensive Heart and CKD I.C.9.a.3 updated guideline Assign codes from combination category I13, Hypertensive heart and chronic kidney disease, when both hypertensive kidney disease and hypertensive heart disease are stated in the diagnosis. Assume a relationship between the hypertension and the chronic kidney disease, whether or not the condition is so designated there is hypertension with both heart and kidney involvement. If heart failure is present, assign an additional code from category I50 to identify the type of heart failure. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease. See Section I.C.14. Chronic kidney disease. The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include

hypertension, heart disease and chronic kidney disease. The Includes note at I13 specifies that the conditions included at I11 and I12 are included together in I13. If a patient has hypertension, heart disease and chronic kidney disease, then a code from I13 should be used, not individual codes for hypertension, heart disease and chronic kidney disease, or codes from I11 or I12. For patients with both acute renal failure and chronic kidney disease, an additional code for acute renal failure is required. Hypertensive Heart and CKD Examples Pt with hypertension, chronic diastolic heart failure, and Stage 2 CKD I13.0 Hypertensive heart and chronic kidney disease with heart failure and

stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease I50.30 Unspecified diastolic heart failure N18.2 Stage 2 CKD Hypertensive Crisis I.C.9.a.10. new guideline Assign a code from category I16, Hypertensive crisis, for documented hypertensive urgency, hypertensive emergency or unspecified hypertensive crisis. Code also any identified hypertensive disease (I10-I15). The sequencing is based on the reason for the encounter.

ST elevation myocardial infarction (STEMI) and non ST elevation MI (NSTEMI) I.C.9.e.1 updated guideline For encounters occurring while the myocardial infarction is equal to, or less than, four weeks old, including transfers to another acute setting or a postacute setting, and the patient requires continued care for the myocardial infarction, and the myocardial infarction meets the definition for other diagnoses (see Section III, Reporting Additional Diagnoses), codes from category I21 may continue to be reported. For encounters after the 4 week time frame and the patient is still receiving care related to the myocardial infarction, the appropriate

aftercare code should be assigned, rather than a code from category I21. For old or healed myocardial infarctions not requiring further care, code I25.2, Old myocardial infarction, may be assigned. Reminder of rules governing Additional Diagnoses Patients admitted with pressure ulcers documented as healing I.C.12.a.5 updated guideline Pressure ulcers described as healing should be assigned the appropriate

pressure ulcer stage code based on the documentation in the medical record. If the documentation does not provide information about the stage of the healing pressure ulcer, assign the appropriate code for unspecified stage. If the documentation is unclear as to whether the patient has a current (new) pressure ulcer or if the patient is being treated for a healing pressure ulcer, query the provider. For ulcers that were present on admission but healed at the time of discharge, assign the code for the site and stage of the pressure ulcer at the time of admission. Patients admitted with pressure ulcer

evolving into another stage during admission I.C.12.a.6 updated guideline If a patient is admitted with a pressure ulcer at one stage and it progresses to a higher stage, assign the code for the highest stage reported for that site two separate codes should be assigned: one code for the site and stage of the ulcer on admission and a second code for the same ulcer site and the highest stage reported during the stay. Coding of Pathological Fractures I.C.13.c updated guideline 7th character A is for use as long as the patient is receiving active treatment for the

fracture. While the patient may be seen by a new or different provider over the course of treatment for a pathological fracture, assignment of the 7th character is based on whether the patient is undergoing active treatment and not whether the provider is seeing the patient for the first time. 7th character D is to be used for encounters after the patient has completed active treatment. The other 7th characters, listed under each subcategory in the Tabular List, are to be used for subsequent encounters for routine care of fractures during the healing and recovery phase as well as treatment of problems associated with the healing, such as malunions, nonunions, and sequelae. Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.

Coding of Pathological Fractures 7th Character A still used during active treatment For treatment after the active phase, use D, G, K, P, or S depending on situation Selection of OB Principal or First Listed Diagnosis - Supervision of High-Risk Pregnancy I.C.15.b.2 guideline updated

Codes from category O09, Supervision of high-risk pregnancy, are intended for use only during the prenatal period. For complications during the labor or delivery episode as a result of a high-risk pregnancy, assign the applicable complication codes from Chapter 15. If there are no complications during the labor or delivery episode, assign code O80, Encounter for full-term uncomplicated delivery. For routine prenatal outpatient visits for patients with high-risk pregnancies, a code from category O09, Supervision of high-risk pregnancy, should be used as the first-listed diagnosis. Secondary chapter 15 codes may be used in conjunction with these codes if appropriate.

Selection of OB Principal When a delivery occurs I.C.15.b.4 updated guideline When a delivery occurs, the principal diagnosis should correspond to the main circumstances or complication of the delivery. When an obstetric patient is admitted and delivers during that admission, the condition that prompted the admission should be sequenced as the principal diagnosis. If multiple conditions prompted the admission, sequence the one most related to the delivery as the principal diagnosis. A code for any complication of the delivery should be assigned as an additional diagnosis. In cases of cesarean delivery, if the patient was admitted with a condition that

resulted in the performance of a cesarean procedure, that condition should be selected as the principal diagnosis. If the reason for the admission was unrelated to the condition resulting in the cesarean delivery, the condition related to the reason for the admission should be selected as the principal diagnosis. Long term use of insulin and oral hypoglycemic (pregnancy and childbirth chapter) I.C.15.h. guideline updated Code Z79.4, Long-term (current) use of insulin, or code Z79.84, Long-term (current) use of oral hypoglycemic drugs, should also be assigned if the diabetes mellitus is being treated with insulin or oral medications. If the patient

is treated with both oral medications and insulin, only the code for insulincontrolled should be assigned. Gestational (pregnancy induced) diabetes I.C.15.i Gestational (pregnancy induced) diabetes can occur during the second and third trimester of pregnancy in women who were not diabetic prior to pregnancy. Gestational diabetes can cause complications in the pregnancy similar to those of pre-existing diabetes mellitus. It also puts the woman at greater risk of developing diabetes after the pregnancy. Codes for gestational diabetes are in subcategory O24.4, Gestational diabetes mellitus. No other code from category O24, Diabetes mellitus in pregnancy, childbirth, and the puerperium, should be used with a code from O24.4. The codes under subcategory O24.4 include diet controlled, insulin controlled, and controlled by oral

hypoglycemic drugs. If a patient with gestational diabetes is treated with both diet and insulin, only the code for insulin controlled is required. If a patient with gestational diabetes is treated with both diet and oral hypoglycemic medications, only the code for "controlled by oral hypoglycemic drugs" is required. Code Z79.4, Long-term (current) use of insulin or code Z79.84, Long-term (current) use of oral hypoglycemic drugs, should not be assigned with codes from subcategory O24.4. An abnormal glucose tolerance in pregnancy is assigned a code from subcategory O99.81, Abnormal glucose complicating pregnancy, childbirth, and the puerperium. Observation and Evaluation of Newborns Suspected Condition not Found I.C.16.b new guideline

1) Assign a code from category Z05, Observation and evaluation of newborns and infants for suspected conditions ruled out, to identify those instances when a healthy newborn is evaluated for a suspected condition that is determined after study not to be present. Do not use a code from category Z05 when the patient has identified signs or symptoms of a suspected problem; in such cases code the sign or symptom. 2) A code from category Z05 may also be assigned as a principal or first-listed code for readmissions or encounters when the code from category Z38 code no longer applies. Codes from category Z05 are for use only for healthy newborns and infants for which no condition after study is found to be present. 3) Z05 on a birth record A code from category Z05 is to be used as a secondary code after the code from category Z38, Liveborn infants according to place of birth and type

of delivery. Coma Scale I.C.18.e updated guideline The coma scale codes (R40.2-) can be used in conjunction with traumatic brain injury codes, acute cerebrovascular disease or sequelae of cerebrovascular disease codes. These codes are primarily for use by trauma registries, but they may be used in any setting where this information is collected. The coma scale may also be used to assess the status of the central nervous system for other non-trauma conditions, such as monitoring patients in the intensive care unit regardless of medical condition. The coma scale codes should be sequenced after the diagnosis code(s).

These codes, one from each subcategory, are needed to complete the scale. The 7 th character indicates when the scale was recorded. The 7th character should match for all three codes. At a minimum, report the initial score documented on presentation at your facility. This may be a score from the emergency medicine technician (EMT) or in the emergency department. If desired, a facility may choose to capture multiple coma scale scores. Assign code R40.24, Glasgow coma scale, total score, when only the total score is documented in the medical record and not the individual score(s). NIHSS Stroke Scale I.C.18.i new guideline The NIH stroke scale (NIHSS) codes (R29.7- -) can be used in conjunction with

acute stroke codes (I63) to identify the patient's neurological status and the severity of the stroke. The stroke scale codes should be sequenced after the acute stroke diagnosis code(s). At a minimum, report the initial score documented. If desired, a facility may choose to capture multiple stroke scale scores. See Section I.B.14. for information concerning the medical record documentation that may be used for assignment of the NIHSS codes. Application of 7th characters in Chapter 19 I.C.19.a updated guideline Paragraphs 1 & 2 (no changes)

7th character A, initial encounter is used for each encounter where the patient is receiving active treatment for the condition. Examples of active treatment are: surgical treatment, emergency department encounter, and evaluation and continuing treatment by the same or different physician 7th character D subsequent encounter is used for encounters after the patient has received completed active treatment of the condition and is receiving routine care for the condition during the healing or recovery phase. Examples of subsequent care are: cast change or removal, an x-ray to check healing status of a fracture, removal of external or internal fixation device, medication adjustment, other aftercare and follow up visits following treatment of the injury or condition. Paragraphs 5 & 6 (no changes)

Initial vs subsequent encounter for fracture I.C.19.c.1 Traumatic fractures are coded using the appropriate 7 th character for initial encounter (A, B, C) while for each encounter where the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion. Paragraphs 2-5 (no changes) The open fracture designations in the assignment of the 7 th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the

7th character for open fracture type I or II should be assigned (B, E, H, M, Q). Paragraph 7 (no changes) Poisoning I.C.19.e.5.b updated guideline When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The

undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings. If there is also a diagnosis of abuse or dependence of the substance, the abuse or dependence is assigned as an additional code. Adult and child abuse, neglect and other maltreatment I.C.19.f guideline updated Paragraphs 1 & 2 (no changes) For cases of confirmed abuse or neglect an external cause code from the assault

section (X92-Y09) should be added to identify the cause of any physical injuries. A perpetrator code (Y07) should be added when the perpetrator of the abuse is known. For suspected cases of abuse or neglect, do not report external cause or perpetrator code. Paragraph 4 (no changes) If a suspected case of alleged rape or sexual abuse is ruled out during an encounter code Z04.41, Encounter for examination and observation following alleged physical adult abuse ruled out adult rape or code Z04.42, Encounter for examination and observation following alleged child rape or sexual abuse rules out, should be used, not a code from T76.

Observation I.C.21.c.6 updated guideline There are three observation Z code categories. They are for use in very limited circumstances when a person is being observed for a suspected condition that is ruled out. The observation codes are not for use if an injury or illness or any signs or symptoms related to the suspected condition are present. In such cases the diagnosis/symptom code is used with the corresponding external cause code. The observation codes are to be used as principal diagnosis only. The only exception to this is when the principal diagnosis is required to be a code from category Z38, Liveborn infants according to place of birth and type of delivery. Then a code from category Z05, Encounter for observation and evaluation of newborn for suspected diseases and conditions ruled out, is sequenced after the Z38 code. Additional codes may be used in addition to the observation code, but only if they are unrelated to the suspected condition being observed.

Paragraphs 3-6 (no changes) The observation Z code categories: Z03 Encounter for medical observation for suspected diseases and conditions ruled out Z04 Encounter for examination and observation for other reasons Except: Z04.9, Encounter for examination and observation for unspecified reason Z05 Encounter for observation and evaluation of newborn for suspected diseases and conditions ruled out Encounters for Obstetrical and Reproductive Services I.C.21.c.11 updated guideline Z codes for pregnancy are for use in those circumstances when none of the problems or

complications included in the codes from the Obstetrics chapter exist (a routine prenatal visit or postpartum care). Codes in category Z34, Encounter for supervision of normal pregnancy, are always first-listed and are not to be used with any other code from the OB chapter. Codes in category Z3A, Weeks of gestation, may be assigned to provide additional information about the pregnancy. Category Z3A codes should not be assigned for pregnancies with abortive outcomes (categories O00-O08), elective termination of pregnancy (code Z33.32), nor for postpartum conditions, as category Z3A is not applicable to these conditions. The date of the admission should be used to determine weeks of gestation for inpatient admissions that encompass more than one gestational week.

Paragraphs 3-5 (no changes) Updates to Section II Selection of Principal Diagnosis Preamble Selection of Principal Diagnosis Section II The circumstances of inpatient admission always govern the selection of principal diagnosis. The principal diagnosis is defined in the Uniform Hospital Discharge Data Set (UHDDS) as that condition established after study to be chiefly responsible for

occasioning the admission of the patient to the hospital for care. The UHDDS definitions are used by hospitals to report inpatient data elements in a standardized manner. These data elements and their definitions can be found in the July 31, 1985, Federal Register (Vol. 50, No, 147), pp. 31038-40. Since that time the application of the UHDDS definitions has been expanded to include all non-outpatient settings (acute care, short term, long term care and psychiatric hospitals; home health agencies; rehab facilities; nursing homes, etc). The UHDDS definitions also apply to hospice services (all levels of care). Paragraphs 4 & 5 (no changes) Updates to Section III

Reporting Additional Guidelines General Rules for other (additional) diagnoses Reporting Additional Diagnoses Section III For reporting purposes the definition for other diagnoses is interpreted as additional conditions that affect patient care in terms of requiring: clinical evaluation; or therapeutic treatment; or diagnostic procedures; or extended length of hospital stay; or

increased nursing care and/or monitoring. The UHDDS item #11-b defines Other Diagnoses as all conditions that coexist at the time of admission, that develop subsequently, or that affect the treatment received and/or the length of stay. Diagnoses that relate to an earlier episode which have no bearing on the current hospital stay are to be excluded. UHDDS definitions apply to inpatients in acute care, short-term, long term care and psychiatric hospital setting. The UHDDS definitions are used by acute care short term hospitals to report inpatient data elements in a standardized manner. These data elements and their definitions can be found in the July 31, 1985, Federal Register (Vol. 50, No, 147), pp. 31038-40. Since that time the application of the UHDDS definitions has been expanded to include all non-outpatient settings (acute care, short term, long term care and psychiatric hospitals; home health agencies; rehab facilities; nursing homes, etc). The UHDDS definitions also apply to hospice services (all levels of care). The following guidelines are to be applied in designating other diagnoses when neither the Alphabetic Index nor the Tabular List

in ICD-10-CM provide direction. The listing of the diagnoses in the patient record is the responsibility of the attending provider. Updates to Section IV Diagnostic Coding and Reporting Guidelines for Outpatient Services General Directions IV.P Diagnostic coding and reporting guidelines for outpatient services Diagnostic Coding and Reporting Guideline for Outpatient Services Section IV

These coding guidelines for outpatient diagnoses have been approved for use by hospitals/ providers in coding and reporting hospital-based outpatient services and provider-based office visits. Guidelines in Section I, Conventions, general coding guidelines and chapter specific guidelines, should also be applied for outpatient services and office visits. Paragraphs 2 & 3 (no changes) Though the conventions and general guidelines apply to all settings, coding guidelines for outpatient and provider reporting of diagnoses will vary in a number of instances from those for inpatient diagnoses, recognizing that: The Uniform Hospital Discharge Data Set (UHDDS) definition of principal diagnosis applies only to inpatients in acute, short-term, long-term and psychiatric hospitals. does not apply to hospital-based outpatient services and provider based office visits.

Coding guidelines for inconclusive diagnoses (probable, suspected, rule out, etc.) were developed for inpatient reporting and do not apply to outpatients. Encounters for general medical examinations with abnormal findings Section IV.P updated guideline The subcategories for encounters for general medical examinations, Z00.0-, provide codes for with and without abnormal findings. Should a general medical examination result in an abnormal finding, the code for general medical examination with abnormal finding should be assigned as the first-listed diagnosis.

An examination with abnormal findings refers to a condition/diagnosis that is newly identified or a change in severity of a chronic condition (such as uncontrolled hypertension, or an acute exacerbation of chronic obstructive pulmonary disease) during a routine physical examination. A secondary code for the abnormal finding should also be coded. PCS Guideline Updates PCS Change Highlights In the Medical and Surgical section, root operation definitions for the root

operations Control and Creation revised In the Extracorporeal Therapies section, new root operation Perfusion created Guidelines B2.1a, B3.2, B3.6b, B3.7, B9, B4.2 and B4.4 revised in response to public comment and Cooperative Parties review. Medical and Surgical Section Guidelines Body System General Guidelines B.2.1.a The procedure codes in the general anatomical regions body systems should only can be used when the procedure is performed on an anatomical region rather than a specific body part (e.g., root operations Control and Detachment,

Drainage of a body cavity) or on the rare occasion when no information is available to support assignment of a code to a specific body part. Examples: Control of postoperative hemorrhage is coded to the root operation Control found in the general anatomical regions body systems. Chest tube drainage of the pleural cavity is coded to root operation Drainage found in the general anatomical regions body system. Suture repair of the abdominal wall is coded to the root operation Repair in the general anatomical regions body system. Multiple Procedures B3.2

During the same operative episode, multiple procedures are coded if: a. The same root operation is performed on different body parts as defined by distinct values of the body part character. Example: Diagnostic excision of liver and pancreas are coded separately. b. The same root operation is repeated in multiple body parts, and those body parts are separate and distinct body parts classified to a single ICD-10-PCS body part value. Example: Excision of the sartorius muscle and excision of the gracilis muscle are both included in the upper leg muscle body part value, and multiple procedures are coded. Extraction of Multiple toenails are coded separately. c. Multiple root operations with distinct objectives are performed on the same body part. Example: Destruction of sigmoid lesion and bypass of sigmoid colon are coded separately. d. The intended root operation is attempted using one approach, but is converted to a different approach. Example: Laparoscopic cholecystectomy converted to an open cholecystectomy is coded as percutaneous endoscopic

Inspection and open Resection. Bypass Procedures B3.6b Coronary arteries are classified by number of distinct sites treated, rather than number of coronary arteries or anatomic name of a coronary artery (e.g., left anterior descending). Coronary artery bypass procedures are coded differently than other bypass procedures as described in the previous guideline. Rather than identifying the body part bypassed from, the body part identifies the number of coronary artery sites bypassed to, and the qualifier specifies the vessel bypassed from.

Example: Aortocoronary artery bypass of one site on the left anterior descending coronary artery and one site on the obtuse marginal coronary artery is classified in the body part axis of classification as two coronary artery sites and the qualifier specifies the aorta as the body part bypassed from. Control vs more definitive root operations B3.7 The root operation Control is defined as, Stopping, or attempting to stop, postprocedural or acute bleeding. If an attempt to stop postprocedural or other acute bleeding is initially unsuccessful, and to stop the bleeding requires performing any of the definitive root operations Bypass, Detachment, Excision,

Extraction, Reposition, Replacement, or Resection, then that root operation is coded instead of Control. Example: Resection of spleen to stop postprocedural bleeding is coded to Resection instead of Control. Excision for Graft B3.9 If an autograft is obtained from a different body part procedure site in order to complete the objective of the procedure, a separate procedure is coded. Example: Coronary bypass with excision of saphenous vein graft, excision of saphenous vein is coded separately.

Body Part Branches of body parts B4.2 Where a specific branch of a body part does not have its own body part value in PCS, the body part is coded to the closest proximal branch that has a specific body part value. In the cardiovascular body systems, if a general body part is available in the correct root operation table, and coding to a prxomial branch would require assignment a code in a different body system, the procedure is coded using the general body part value. Examples: A procedure performed on the mandibular branch of the trigeminal nerve is coded to the trigeminal nerve body part value.

Occlusion of the bronchial artery is coded to the body part value Upper Artery in the body system Upper Arteries and not to the body part value Thoracic Aorta, Descending in the body system Heart and Great Vessels. Body Part Coronary arteries B4.4 The coronary arteries are classified as a single body part that is further specified by number of sites arteries treated. and not by name or number of arteries. Separate body part values are used to specify the number of sites treated when the same procedure is performed on multiple sites in the coronary arteries. One procedure code specifying multiple arteries is used when the same procedure is performed, including the same device and qualifier values.

Examples: Angioplasty of two distinct coronary arteries sites in the left anterior descending coronary artery with placement of two stents is coded as Dilation of Coronary Arteries, Two Sites Arteries, with Two Intraluminal Devices. Angioplasty of two distinct sites in the left anterior descending coronary artery, coronary arteries, one with stent placed and one without, is coded separately as Dilation of Coronary Artery, One Site Artery with Intraluminal Device, and Dilation of Coronary Artery, One Site Artery with no device. Root Operation Control updated Prior to 2017: Definition: Stopping, or attempting to stop, postprocedural bleeding

After 2017 update Definition: Stopping, or attempting to stop, postprocedural or other acute bleeding. Root Operation Creation updated Prior to 2017 Definition: Making a new genital structure that does not take over the function of a body part After 2017 Update Definition: Putting in or on biological or synthetic material to form a new body part that, to the

extent possible, replicates the anatomic structure or function of an absent body part New Root Operation in Extracorporeal Therapies = Perfusion Root Operation (Third Character) B Definition: Extracorporeal treatment by diffusion of therapeutic fluid Questions?
