Atresia of nares (anterior) (posterior)
Congenital stenosis of nares (anterior) (posterior)

Excludes1 inherited from the categories above Q30.0

These are not written on Q30.0, but they bind it: a note on a category applies to every code beneath it. Billing Q30.0 with anything listed here is a denial.

Written on Q30 — Congenital malformations of nose

congenital deviation of nasal septum (Q67.4)

Risk adjustment

Q30.0 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

Q30.0 is named in 8 Medicare coverage policies — 8 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
