G61.9 — Inflammatory polyneuropathy, unspecified
G61.9 is a billable, specific ICD-10-CM code for inflammatory polyneuropathy, unspecified. It is valid for submission on a claim.
Risk adjustment
G61.9 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
G61.9 is named in 8 Medicare coverage policies — 4 listing it as supporting medical necessity, and 4 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
