Q16.0 — Congenital absence of (ear) auricle
Q16.0 is a billable, specific ICD-10-CM code for congenital absence of (ear) auricle. It is valid for submission on a claim.
Other codes that can never be billed with Q16.0
These codes carry an Excludes1 note pointing at Q16.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q16.0 alone.
- Q17Other congenital malformations of ear
Risk adjustment
Q16.0 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
Q16.0 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.
