Z99.2Dependence on renal dialysis

Z99.2 is the ICD-10-CM diagnosis code for dependence on renal dialysis. It belongs to category Z99 (dependence on enabling machines and devices, 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z99 (dependence on enabling machines and devices, not elsewhere classified), Z99.2 is specifically for dependence on renal dialysis. Related codes cover aspirator (Z99.0), respirator (Z99.1), wheelchair (Z99.3) and other enabling machines and devices (Z99.8).

Don't report Z99.2 together with the conditions in its Excludes1 note: encounter for fitting and adjustment of dialysis catheter (Z49.0-).

The conditions in its Excludes2 note aren't part of Z99.2, but may be coded alongside it if the patient has both: noncompliance with renal dialysis (Z91.15-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as V45.11 (renal dialysis status).
