Endometriosis of left fallopian tube, unspecified depth

This code signifies the presence of endometrial tissue abnormally located within the left fallopian tube, without further specification of how deeply the tissue has infiltrated the tubal wall. This condition can lead to inflammation, scarring, and pain, potentially affecting fertility.

Apply this code when documentation confirms endometriosis specifically affecting the left fallopian tube, but the depth of involvement is not specified by the provider. This is often used when initial diagnostic imaging or surgical findings identify the location without detailed histological depth.

• Ensure the documentation explicitly states "left fallopian tube" and does not specify depth.
• Distinguish from endometriosis of the right fallopian tube or bilateral involvement.
• If depth is specified (e.g., superficial, deep), a more specific subcategory code should be used.
