H25.9 — Unspecified age-related cataract
H25.9 is a billable, specific ICD-10-CM code for unspecified age-related cataract. It is valid for submission on a claim.
Risk adjustment
H25.9 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
H25.9 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.
