Other codes that can never be billed with J33

J32.2Chronic ethmoidal sinusitis

J33 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 J33

4 child codes. Green means billable.
