Non-billable headerICD-10-CM

Other codes that can never be billed with T26

- H10.21Acute toxic conjunctivitis
Risk adjustment
T26 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 T26
