J33.8 — Other polyp of sinus

Other codes that can never be billed with J33.8
These codes carry an Excludes1 note pointing at J33.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J33.8 alone.
- D14.0Benign neoplasm of middle ear, nasal cavity and accessory sinuses
Risk adjustment
J33.8 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
J33.8 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
