Endometriosis of other specified sites

This code signifies the presence of endometrial tissue growing outside the uterus in locations other than the ovaries, fallopian tubes, pelvic peritoneum, rectovaginal septum, or intestine. These ectopic growths can cause pain, inflammation, and adhesions, impacting various organ systems.

Apply this code when documentation specifies endometriosis in unusual or less common sites, such as the bladder, diaphragm, surgical scars, or pleura. The physician's notes must clearly identify the specific extra-pelvic or atypical location of the endometrial implants.

• Ensure the documentation explicitly states a site other than those covered by more specific endometriosis codes (e.g., ovarian, intestinal).
• Avoid using this code if the site is unspecified; instead, use the appropriate unspecified endometriosis code.
• Always review operative reports and pathology findings for definitive site identification.
