Endometriosis of the anterior abd wall, unspecified depth

This code describes the presence of endometrial-like tissue located on the anterior abdominal wall, outside of the uterus. This ectopic tissue can cause pain, swelling, or a palpable mass in the abdominal wall, often correlating with the menstrual cycle. The "unspecified depth" indicates that the extent of involvement within the abdominal wall layers (e.g., subcutaneous, muscle) is not documented.

Use this code when documentation confirms endometriosis specifically located in the anterior abdominal wall, and the depth of involvement is not specified. This typically arises from surgical pathology reports, imaging findings, or clinical examination notes describing an abdominal wall mass consistent with endometriosis. It is often seen in patients with a history of abdominal surgery, such as a C-section.

• Ensure documentation explicitly states "anterior abdominal wall" and not just "abdominal wall" to avoid miscoding.
• Do not use this code if the depth of involvement (e.g., subcutaneous, muscle) is clearly specified; look for more specific codes within the N80.C category.
• Consider sequencing this code after a code for chronic pain if pain is a primary symptom and documented as such.
