Q27.1 — Congenital renal artery stenosis
Q27.1 is a billable, specific ICD-10-CM code for congenital renal artery stenosis. It is valid for submission on a claim.
Other codes that can never be billed with Q27.1
These codes carry an Excludes1 note pointing at Q27.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q27.1 alone.
- N28.0Ischemia and infarction of kidney
Risk adjustment
Q27.1 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
Q27.1 is named in 7 Medicare coverage policies — 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
