N41.8 — Other inflammatory diseases of prostate
N41.8 is a billable, specific ICD-10-CM code for other inflammatory diseases of prostate. It is valid for submission on a claim.
Other codes that can never be billed with N41.8
These codes carry an Excludes1 note pointing at N41.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N41.8 alone.
- N42.1Congestion and hemorrhage of prostate
Risk adjustment
N41.8 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
N41.8 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A57427Billing and Coding: Transrectal Ultrasound
