Superficial endometriosis of the right pelvic brim

This code signifies the presence of endometrial-like tissue growing on the surface of the right pelvic brim, a bony ridge forming part of the pelvic inlet. This is a form of superficial endometriosis, meaning the implants are not deeply invasive into the underlying tissues. It specifically identifies the laterality and anatomical location of the endometrial lesions.

Use this code when documentation explicitly states superficial endometriosis affecting the right pelvic brim. This diagnosis is typically made during laparoscopic examination or other surgical procedures where direct visualization and/or biopsy confirm the location and superficial nature of the endometrial implants.

• Ensure documentation specifies "superficial" and "right pelvic brim" to accurately assign this code.
• Distinguish from deep infiltrating endometriosis, which would be coded differently based on depth and specific organ involvement.
• Always code the primary site of endometriosis; if multiple sites are involved, sequence the most clinically significant or treated site first, followed by additional codes for other locations.
