Non-billable headerICD-10-CM
T20 is a non-billable header ICD-10-CM code for burn and corrosion of head, face, and neck. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Other codes that can never be billed with T20
These codes carry an Excludes1 note pointing at T20. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T20 alone.
Risk adjustment
T20 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.
