Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to Z86.39: its own notes plus those printed at Z86, block Z77-Z99, and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Code First
The underlying condition named in the note is sequenced before this code.
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.

Questions About Z86.39Overview
What is the ICD-10 code for personal history of other endocrine, nutritional and metabolic disease?
The ICD-10-CM code for personal history of other endocrine, nutritional and metabolic disease is Z86.39 (sometimes written as Z8639). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z86.39 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of other endocrine, nutritional and metabolic disease on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z86.39 group to?
On inpatient claims, personal history of other endocrine, nutritional and metabolic disease maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.
Can Z86.39 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of other endocrine, nutritional and metabolic disease describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z86.39 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 personal history of other endocrine, nutritional and metabolic disease 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.
