N30.01 — Acute cystitis with hematuria
N30.01 is a billable, specific ICD-10-CM code for acute cystitis with hematuria. It is valid for submission on a claim.
Other codes that can never be billed with N30.01
These codes carry an Excludes1 note pointing at N30.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N30.01 alone.
Risk adjustment
N30.01 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
N30.01 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
