G24.3 — Spasmodic torticollis
G24.3 is a billable, specific ICD-10-CM code for spasmodic torticollis. It is valid for submission on a claim.
Other codes that can never be billed with G24.3
These codes carry an Excludes1 note pointing at G24.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G24.3 alone.
Risk adjustment
G24.3 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
G24.3 is named in 55 Medicare coverage policies — 55 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
