About coding dialysis status
The ICD-10-CM code for dialysis status is Z99.2 (Dependence on renal dialysis).
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-).
Don't confuse with (Excludes1 for Z99.2)
- encounter for fitting and adjustment of dialysis catheter (Z49.0-)
