Endometriosis of the anterior abd wall, subcutaneous tissue

This code signifies the presence of endometrial tissue implants within the subcutaneous fat and fascia of the anterior abdominal wall. This condition, often presenting as a painful mass or nodule, is a form of extrapelvic endometriosis.

Use this code for patients diagnosed with endometriosis specifically located in the subcutaneous tissue of the anterior abdominal wall, typically confirmed by imaging or biopsy. It is commonly seen following abdominal surgeries, particularly C-sections, where endometrial cells may have been inadvertently implanted. Documentation should clearly specify the location as subcutaneous anterior abdominal wall.

• Differentiate from other abdominal wall masses; definitive diagnosis of endometriosis is crucial.
• Do not use for endometriosis confined to the pelvic organs or other extrapelvic sites.
• Consider sequencing this code after a code for chronic pain if pain is a significant presenting symptom.
