Official Description

Lymphangiography, pelvic/abdominal, unilateral, radiological supervision and interpretation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 75805 refers to the procedure known as lymphangiography, specifically focusing on the pelvic and abdominal regions, performed unilaterally. This procedure involves the use of radiological techniques to visualize the lymphatic system, which is crucial for diagnosing various conditions related to lymphatic flow and function. During lymphangiography, a physician conducts radiological supervision and interpretation, ensuring that the imaging process is accurately monitored and assessed. The procedure begins with the preparation of the patient, where the skin of the foot is cleansed, and a blue indicator dye is injected between the toes. This dye serves as a tracer, allowing the physician to observe its movement through the lymphatic vessels. The observation period typically lasts between 15 to 30 minutes, during which the physician assesses the spread of the dye into the small lymph vessels of the foot. Once adequate delineation of the lymph vessels is achieved, a local anesthetic is administered, followed by an incision to expose one of the larger lymph vessels. A needle or catheter is then inserted into the exposed vessel to inject contrast media, which enhances the visibility of the lymphatic structures during imaging. Radiographs are subsequently obtained, capturing detailed images of the lymph vessels in the abdomen and/or pelvis over a duration of 1 to 2 hours. The physician concludes the procedure by reviewing the radiographs and providing a comprehensive written interpretation of the findings. It is important to note that for a unilateral lymphangiogram of the abdomen or pelvis, the appropriate code to use is 75805, while 75807 should be utilized if a bilateral imaging procedure is conducted.

1. Indications

The lymphangiography procedure, represented by CPT® Code 75805, is indicated for various clinical scenarios where visualization of the lymphatic system is necessary. The following conditions may warrant the performance of this procedure:

  • Evaluation of Lymphedema: Lymphangiography is often performed to assess the presence and extent of lymphedema, a condition characterized by swelling due to lymphatic obstruction.
  • Investigation of Lymphatic Malformations: This procedure can help identify congenital or acquired malformations of the lymphatic system, which may lead to complications such as fluid accumulation.
  • Assessment of Lymphatic Metastasis: Lymphangiography is utilized to evaluate the spread of cancer to lymph nodes, aiding in staging and treatment planning for malignancies.
  • Diagnosis of Lymphatic Obstruction: The procedure assists in diagnosing blockages within the lymphatic vessels, which can result from various causes, including trauma or surgical interventions.

2. Procedure

The lymphangiography procedure involves several critical steps to ensure accurate imaging and assessment of the lymphatic system. The following outlines the procedural steps involved:

  • Step 1: Preparation and Injection of Dye - The procedure begins with the patient being positioned appropriately, followed by the cleansing of the skin on the foot. A blue indicator dye is then injected between several toes to visualize the lymphatic vessels. This step is crucial as it allows the physician to observe the dye's movement into the small lymph vessels, which typically takes 15 to 30 minutes.
  • Step 2: Local Anesthetic Administration - Once there is adequate delineation of the lymph vessels in the foot, a local anesthetic is injected over one of the larger lymph vessels to minimize discomfort during the subsequent steps.
  • Step 3: Incision and Exposure of Lymph Vessel - The physician makes a small incision in the skin to expose the lymph vessel. This step is essential for accessing the lymphatic system directly for further intervention.
  • Step 4: Injection of Contrast Media - A needle or catheter is inserted into the exposed lymph vessel, and contrast media is injected. This contrast agent enhances the visibility of the lymphatic structures during imaging.
  • Step 5: Radiographic Imaging - Radiographs are obtained of the lymph vessels in the abdomen and/or pelvis. This imaging process is conducted over a period of 1 to 2 hours, allowing for comprehensive visualization of the lymphatic system.
  • Step 6: Interpretation of Results - After the imaging is complete, the physician reviews the radiographs and provides a written interpretation of the findings, which is critical for determining the next steps in patient management.

3. Post-Procedure

Following the lymphangiography procedure, patients may require specific post-procedure care to ensure proper recovery and monitoring. It is essential to observe the injection site for any signs of infection or adverse reactions to the dye or contrast media. Patients may experience mild discomfort or swelling at the injection site, which typically resolves within a few days. Additionally, the physician may provide instructions regarding activity restrictions and follow-up appointments to discuss the results of the imaging and any further diagnostic or therapeutic interventions that may be necessary based on the findings. Monitoring for any unusual symptoms, such as increased pain or swelling, is also advised, and patients should be encouraged to report any concerns to their healthcare provider promptly.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
GC This service has been performed in part by a resident under the direction of a teaching physician
