Superficial endometriosis of diaphragm

This code describes the presence of endometrial-like tissue on the surface of the diaphragm, a condition known as superficial diaphragmatic endometriosis. This ectopic tissue responds to hormonal fluctuations, potentially causing pain and other symptoms, particularly during menstruation.

Apply this code when documentation explicitly states superficial endometriosis affecting the diaphragm. This diagnosis is often made during laparoscopic exploration for pelvic pain or infertility, or when imaging studies suggest diaphragmatic involvement.

• Differentiate from deep infiltrating endometriosis of the diaphragm, which has a separate code.
• Ensure the documentation specifies "superficial" to accurately assign this code.
• Consider sequencing with codes for associated symptoms (e.g., chronic pelvic pain, dyspnea) if applicable.
