G37 — Other demyelinating diseases of central nervous system
Non-billable headerICD-10-CM
G37 is a non-billable header ICD-10-CM code for other demyelinating diseases of central nervous system. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with G37
These codes carry an Excludes1 note pointing at G37. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G37 alone.
Risk adjustment
G37 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.
