Billable

Endometriosis of lung

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Endometrial tissue is growing within the lung tissue itself, which can cause chest pain, coughing, and breathing difficulties.

Coding Tips

  • •Pulmonary endometriosis is rare; document whether involvement is unilateral or bilateral
  • •Distinguish between pleural (N80.B1) and lung parenchymal involvement when coding
