Superficial endometriosis of bilateral fallopian tubes

This code signifies the presence of endometrial tissue on the surface of both fallopian tubes. This condition is a form of endometriosis where the ectopic endometrial implants are located superficially on the tubal serosa, rather than invading deeper tissues. It can contribute to pelvic pain and infertility.

Apply this code when documentation explicitly states superficial endometriosis affecting both fallopian tubes. This diagnosis is typically made during laparoscopic examination or other surgical procedures where direct visualization and/or biopsy confirms the presence of endometrial implants on the tubal surface.

• Ensure documentation specifies "superficial" involvement; otherwise, a more general endometriosis code for the fallopian tubes may be appropriate.
• Confirm laterality is explicitly "bilateral" in the physician's notes. If only one tube is affected, a unilateral code should be used.
• Do not confuse with deep infiltrating endometriosis of the fallopian tubes, which involves deeper tissue invasion and has different code assignments.
