G24.5

G24.5 — Blepharospasm

Billable / specific codeICD-10-CM

G24.5 is a billable, specific ICD-10-CM code for blepharospasm. It is valid for submission on a claim.

Risk adjustment

G24.5 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

G24.5 is named in 34 Medicare coverage policies — 34 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
