N99.5 — Complications of stoma of urinary tract
N99.5 is a non-billable header ICD-10-CM code for complications of stoma of urinary tract. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- mechanical complication of urinary catheter (T83.0-)
Other codes that can never be billed with N99.5
These codes carry an Excludes1 note pointing at N99.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N99.5 alone.
Risk adjustment
N99.5 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead N99.5
3 child codes. Green means billable.
