Other codes that can never be billed with E74.818
These codes carry an Excludes1 note pointing at E74.818. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E74.818 alone.
- R81Glycosuria
Risk adjustment
E74.818 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.
