Q15.0 — Congenital glaucoma
Q15.0 is a billable, specific ICD-10-CM code for congenital glaucoma. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Axenfeld's anomaly

- Macrocornea with glaucoma
- Macrophthalmos in congenital glaucoma
- Megalocornea with glaucoma
Other codes that can never be billed with Q15.0
These codes carry an Excludes1 note pointing at Q15.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q15.0 alone.
Risk adjustment
Q15.0 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
Q15.0 is named in 20 Medicare coverage policies — 20 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
