N29 — Other disorders of kidney and ureter in diseases classified elsewhere
N29 is a billable, specific ICD-10-CM code for other disorders of kidney and ureter in diseases classified elsewhere. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Code first
The underlying condition must be sequenced before this code.
Other codes that can never be billed with N29
These codes carry an Excludes1 note pointing at N29. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N29 alone.
- N35.1Postinfective urethral stricture, not elsewhere classified
Risk adjustment
N29 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.
Medicare coverage
N29 is named in 4 Medicare coverage policies — 4 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How N29 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to N29.
