About Z91.15

Z91.15 is the ICD-10-CM diagnosis code for patient's noncompliance with renal dialysis. 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 (patient's noncompliance with medical treatment and regimen), Z91.15 is specifically for patient's noncompliance with renal dialysis. Related codes cover noncompliance with dietary regimen (Z91.11), intentional underdosing of medication regimen (Z91.12), unintentional underdosing of medication regimen (Z91.13), other noncompliance with medication regimen (Z91.14) and noncompliance with other medical treatment and regimen (Z91.19).

To report this condition, pick the subcode that matches the documentation: Z91.151 (due to financial hardship) and Z91.158 (for other reason).

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 V45.12 (noncompliance with renal dialysis).
