2025 CPT code 75805

This code represents the radiological supervision and interpretation of a unilateral lymphangiogram of the pelvic or abdominal area.

Modifiers 26 (professional component) and TC (technical component) can be used to indicate which part of the procedure is being billed. Modifier 59 may be necessary if the lymphangiogram is performed with another procedure that is usually not reported together.

Yes, modifiers are applicable.

Medical necessity must be established for each instance of lymphangiography. The documentation should clearly support the need for the procedure to diagnose or evaluate a specific medical condition related to the lymphatic system.

The physician is responsible for supervising and interpreting the radiological images obtained during the lymphangiography.

IMPORTANT For bilateral lymphangiography of the pelvic or abdominal area, use 75807. For lymphangiography of an extremity, use 75801 (unilateral) or 75803 (bilateral). The injection procedure for lymphangiography is reported separately with code 38790.

In simple words: This procedure uses a special dye and x-rays to create images of the lymph vessels in your abdomen or pelvis to check for problems. The doctor injects the dye into a lymph vessel, usually in your foot. The doctor monitors and interprets the x-ray images during the exam.

This procedure involves injecting a contrast agent into the lymphatic system of the pelvis or abdomen and then taking x-ray images to visualize the lymphatic vessels and nodes. This code includes the physician’s supervision and interpretation of the imaging. This is a unilateral procedure, meaning it is performed on only one side of the body.

Example 1: A patient presents with unexplained swelling in the left leg. To evaluate the lymphatic system for potential blockage or abnormalities, a unilateral lymphangiogram of the left pelvic and abdominal area is performed., A patient has a history of lymphoma. To assess the extent of the disease and to monitor response to treatment, a unilateral lymphangiogram of the abdominal area is performed., A patient has abnormal lymph nodes detected on a CT scan of the abdomen. To evaluate the lymphatic vessels and nodes in detail, a unilateral lymphangiogram of the affected area of the abdomen is performed.

Documentation should include the medical necessity for the procedure, the area imaged (pelvic or abdominal, unilateral), details about the contrast injection, a description of the findings, and the physician’s interpretation of the images.

** Lymphangiography has largely been replaced by other imaging modalities like CT and MRI. Therefore it is now considered a less common procedure. However, in certain situations, it can still provide valuable information about the lymphatic system that may not be obtainable through other means.
