Other codes that can never be billed with E05.8
These codes carry an Excludes1 note pointing at E05.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E05.8 alone.
- E22Hyperfunction of pituitary gland
Risk adjustment
E05.8 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.
Code to one of these instead E05.8
