Other codes that can never be billed with T78.071

These codes carry an Excludes1 note pointing at T78.071. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T78.071 alone.

T78.071 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.
