Endometriosis of right fallopian tube, unspecified depth

This code signifies the presence of endometrial tissue abnormally located within the right fallopian tube, without further specification of how deeply the tissue has infiltrated the tubal wall. This condition can lead to inflammation, scarring, and potential infertility or ectopic pregnancy.

Apply this code when documentation confirms endometriosis affecting the right fallopian tube, but the extent or depth of involvement is not specified. This is appropriate for initial diagnoses or when imaging/surgical reports identify right fallopian tube endometriosis without further detail on its penetration.

• Ensure the documentation explicitly states "right fallopian tube" and "endometriosis."
• If the depth of infiltration is known (e.g., superficial, deep), a more specific subcategory code should be used.
• Consider sequencing this code after any related infertility or pelvic pain diagnoses if they are the primary reason for the encounter.
