Official Description

Injection procedure; lymphangiography

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 38790 refers to an injection procedure known as lymphangiography. This diagnostic imaging technique is utilized to visualize the lymphatic system, which is a crucial component of the body's immune system and fluid balance. The procedure begins with the cleansing of the skin on the foot, ensuring a sterile environment for the injection. A blue indicator dye is then injected between several toes, allowing for the observation of the dye's movement as it spreads into the small lymph vessels of the foot. This observation period typically lasts between 15 to 30 minutes, during which the provider assesses the delineation of the lymph vessels. Once adequate visualization is achieved, a local anesthetic is administered over one of the larger lymph vessels to minimize discomfort during the subsequent steps. The skin is then incised to expose the lymph vessel, allowing for the insertion of a needle or catheter. Contrast media is injected into the exposed lymph vessel, which is essential for obtaining clear images of the lymphatic system. The lymphangiograms, which are separate diagnostic images, are captured as the contrast travels through the lymph vessels, providing valuable information about the condition of the lymphatic system. This procedure may also include imaging of the extremity vessels and/or pelvic and/or abdominal vessels, depending on the clinical indications and the areas of interest for the diagnostic evaluation.

1. Indications

The lymphangiography procedure is indicated for various clinical scenarios where visualization of the lymphatic system is necessary. The following conditions may warrant this procedure:

  • Assessment of Lymphatic Obstruction This procedure is performed to evaluate suspected blockages or obstructions within the lymphatic vessels, which can lead to conditions such as lymphedema.
  • Investigation of Lymphatic Malformations Lymphangiography is indicated for diagnosing congenital or acquired malformations of the lymphatic system, which may require further intervention.
  • Evaluation of Tumors The procedure can be utilized to assess the involvement of lymph nodes by tumors, aiding in staging and treatment planning for malignancies.
  • Preoperative Mapping Lymphangiography may be indicated for preoperative mapping of lymphatic drainage patterns, particularly in surgical procedures involving lymph nodes.

2. Procedure

The lymphangiography procedure involves several detailed steps to ensure accurate imaging of the lymphatic system. The following procedural steps are performed:

  • Step 1: Skin Preparation The procedure begins with the thorough cleansing of the skin on the foot to create a sterile field. This is crucial to prevent any potential infections during the injection process.
  • Step 2: Injection of Indicator Dye A blue indicator dye is injected between several toes. This dye serves as a visual marker, allowing the provider to observe its spread into the small lymph vessels of the foot.
  • Step 3: Observation Period After the dye injection, the provider waits for a period of 15 to 30 minutes. During this time, the provider observes the movement of the dye, ensuring that there is good delineation of the lymph vessels in the foot.
  • Step 4: Local Anesthetic Administration Once adequate visualization of the lymph vessels is achieved, a local anesthetic is injected over one of the larger lymph vessels. This step is essential for minimizing discomfort during the incision and exposure of the lymph vessel.
  • Step 5: Incision and Exposure The skin is incised to expose the lymph vessel. This step allows for direct access to the lymphatic system for further intervention.
  • Step 6: Insertion of Needle or Catheter A needle or catheter is inserted into the exposed lymph vessel. This is a critical step for the subsequent injection of contrast media.
  • Step 7: Injection of Contrast Media Contrast media is injected into the exposed lymph vessel. This substance is vital for enhancing the visibility of the lymphatic structures during imaging.
  • Step 8: Obtaining Lymphangiograms As the contrast travels through the lymph vessels, separate lymphangiograms are obtained. These images provide detailed information about the lymphatic system and may include views of the extremity vessels and/or pelvic and/or abdominal vessels, depending on the clinical requirements.

3. Post-Procedure

After the lymphangiography procedure, patients may be monitored for any immediate adverse reactions to the dye or contrast media. It is essential to observe the injection site for signs of infection or complications. Patients are typically advised to rest and may be given specific instructions regarding activity levels and care of the injection site. Follow-up imaging or assessments may be scheduled to evaluate the results of the lymphangiography and to determine any further necessary interventions based on the findings.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
LT Left side (used to identify procedures performed on the left side of the body)
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
RT Right side (used to identify procedures performed on the right side of the body)
GC This service has been performed in part by a resident under the direction of a teaching physician
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
