N80.B1
BillableEndometriosis of pleura
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Endometrial tissue (the lining of the uterus) is growing on the pleura, which is the membrane that lines the lungs and chest cavity.
Coding Tips
- •Pleural endometriosis is rare; ensure documentation clearly indicates pleural involvement rather than lung parenchymal involvement
- •This code is distinct from N80.B2 (lung endometriosis); verify the exact anatomical location
