These codes carry an Excludes1 note pointing at T65.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T65.3 alone.
- T52.1Toxic effects of benzene
Risk adjustment
T65.3 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 T65.3
