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 Z73.6Overview
What is the ICD-10 code for limitation of activities due to disability?
The ICD-10-CM code for limitation of activities due to disability is Z73.6 (sometimes written as Z736). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z73.6 (Problems related to life management difficulty) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report limitation of activities due to disability on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z73.6 group to?
On inpatient claims, limitation of activities due to disability 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 Z73.6 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because limitation of activities due to disability describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z73.6 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 limitation of activities due to disability on inpatient claims. The code appears in the Persons encountering health services in other circumstances (Z69-Z76) range of the CMS exempt list.
