Q25.3

Q25.3 — Supravalvular aortic stenosis

Billable / specific codeICD-10-CMPOA exempt

Q25.3 is a billable, specific ICD-10-CM code for supravalvular aortic stenosis. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

congenital aortic stenosis NOS (Q23.0)
congenital stenosis of aortic valve (Q23.0)

Other codes that can never be billed with Q25.3

These codes carry an Excludes1 note pointing at Q25.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q25.3 alone.

Q23.0Congenital stenosis of aortic valve

Risk adjustment

Q25.3 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

Q25.3 is named in 23 Medicare coverage policies — 23 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
