Endometriosis of right ureter, unspecified depth

This code signifies the presence of endometrial tissue abnormally located within the right ureter, without specifying how deeply the tissue has invaded the ureteral wall. This condition can lead to symptoms such as flank pain, hematuria, and hydronephrosis due to ureteral obstruction.

Use this code when documentation confirms endometriosis affecting the right ureter, but the specific depth of invasion (e.g., superficial, deep) is not documented. This code is appropriate when imaging studies (e.g., MRI, CT, ultrasound) or surgical findings indicate right ureteral involvement by endometriosis.

• Ensure the laterality (right ureter) is clearly documented.
• If the depth of endometriosis is specified (e.g., superficial, deep), use a more specific subcategory code.
• Code any associated complications, such as hydronephrosis (N13.x), separately.
