Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to Z82.49: its own notes plus those printed at block Z77-Z99 and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Code Also
A second code may be needed to fully describe the condition; the note gives no sequencing direction.
Notes
General instructions on how these codes are used.
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Family History
Your family history includes health information about you and your close relatives. Families have many factors in common, including their genes, environment, and lifestyle. Looking at these factors can help you figure out whether you have a higher risk for certain health problems, such as heart disease, stroke, and cancer.

Questions About Z82.49Overview
Is Z82.49 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report family history of ischemic heart disease and other diseases of the circulatory system on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z82.49 group to?
On inpatient claims, family history of ischemic heart disease and other diseases of the circulatory system maps to MS-DRG 951, 795, with relative weights from 0.2022 to 0.5574 depending on complications. Higher weights mean higher Medicare reimbursement.
Can Z82.49 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of ischemic heart disease and other diseases of the circulatory system describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z82.49 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for family history of ischemic heart disease and other diseases of the circulatory system on inpatient claims. The code appears in the Persons with potential health hazards related to family and personal history and certain conditions influencing health status (Z77-Z99) range of the CMS exempt list.
What is the ICD-9 equivalent of Z82.49?
Under the General Equivalence Mappings, family history of ischemic heart disease and other diseases of the circulatory system converts to ICD-9-CM V17.3 (fam hx-ischem heart dis) and V17.49 (fam hx-cardiovas dis NEC). The mapping is approximate, so confirm the match fits the documentation.
