- underlying condition, such as:
- catamenial pneumothorax due to endometriosis (N80.B-)
- cystic fibrosis (E84.-)

Risk adjustment
J93.12 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.
