R41.2 — Retrograde amnesia
R41.2 is a billable, specific ICD-10-CM code for retrograde amnesia. It is valid for submission on a claim.
Other codes that can never be billed with R41.2
These codes carry an Excludes1 note pointing at R41.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R41.2 alone.
Risk adjustment
R41.2 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
R41.2 is named in 15 Medicare coverage policies — 15 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
