Z91.14Patient's other noncompliance with medication regimen

Z91.14 is the ICD-10-CM diagnosis code for patient's other noncompliance with medication regimen. It belongs to category Z91 (personal risk factors, not elsewhere classified), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Z91.1, choose Z91.14 (other noncompliance with medication regimen) only when documentation doesn't support a more specific option: noncompliance with dietary regimen (Z91.11), intentional underdosing of medication regimen (Z91.12), unintentional underdosing of medication regimen (Z91.13), noncompliance with renal dialysis (Z91.15) and noncompliance with other medical treatment and regimen (Z91.19).

To report this condition, pick the subcode that matches the documentation: Z91.141 (due to financial hardship) and Z91.148 (for other reason).

Code first: , if applicable, adverse effect of underdosing (T36-T50).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2023 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as V15.81 (personal history of noncompliance with medical treatment, presenting hazards to health).
