Deep endometriosis of left fallopian tube

This code signifies the presence of endometrial-like tissue deeply infiltrating the wall of the left fallopian tube. This condition can cause significant pain, inflammation, and potential obstruction of the fallopian tube, impacting fertility.

Apply this code when documentation explicitly states deep endometriosis affecting the left fallopian tube, often identified during laparoscopic surgery or imaging studies. Supporting documentation should detail the location and depth of the endometrial implants.

• Differentiate from superficial endometriosis of the fallopian tube, which would use a different subcategory.
• Ensure laterality (left) is clearly documented; separate codes exist for right or bilateral involvement.
• Consider sequencing with codes for associated symptoms (e.g., chronic pelvic pain, infertility) or complications.
