Official Description

Transluminal balloon angioplasty (except dialysis circuit), open or percutaneous, including all imaging and radiological supervision and interpretation necessary to perform the angioplasty within the same vein; each additional vein (List separately in addition to code for primary procedure)

Common Language Description

Transluminal balloon angioplasty is a specialized endovascular procedure designed to treat narrowing or obstruction in veins. This technique employs fluoroscopy, a type of medical imaging that allows real-time visualization of the veins during the procedure. The process begins with accessing the vein, which can be achieved either percutaneously or through an open surgical approach. In the percutaneous method, a needle is inserted through the skin into a blood vessel located in the groin, arm, or neck. A guidewire is then threaded through this needle, and the needle is subsequently replaced with a vascular sheath to facilitate the introduction of other instruments. In contrast, the open access method involves making an incision directly over the targeted vessel, allowing for direct access to the vein. Once access is established, a vascular catheter is inserted over the guidewire, and contrast dye is injected to enhance the visibility of the vein and to identify any areas of narrowing or disease. Following this, the vascular catheter is replaced with a balloon catheter, which is carefully advanced to the site of the obstruction. The balloon is then inflated with a dilute contrast dye, which serves to expand the vessel and alleviate the blockage. After a predetermined duration, the balloon is deflated and removed. To ensure the effectiveness of the procedure, a vascular catheter is reinserted, and angiography is performed again to assess whether the vein has been successfully opened or if there remains any residual stenosis that may require further intervention. The CPT® Code 37248 is used to report the balloon angioplasty performed on the initial vein, while CPT® Code 37249 is designated for each additional vein treated during the same session.

1. Indications

The procedure of transluminal balloon angioplasty is indicated for patients presenting with specific conditions that lead to narrowing or obstruction of veins. These indications may include:

  • Venous Obstruction: Conditions that cause blockages in the veins, leading to impaired blood flow.
  • Venous Stenosis: Narrowing of the vein that can result from various factors, including previous thrombosis or other vascular diseases.
  • Symptoms of Venous Insufficiency: Patients may experience symptoms such as swelling, pain, or skin changes due to inadequate venous return.

2. Procedure

The transluminal balloon angioplasty procedure involves several critical steps to ensure successful treatment of the affected veins. These steps include:

  • Step 1: Accessing the Vein - The procedure begins with the establishment of access to the targeted vein. This can be done percutaneously by inserting a needle through the skin into a blood vessel in the groin, arm, or neck. A guidewire is then threaded through the needle, which is subsequently replaced with a vascular sheath to facilitate further instrumentation. Alternatively, an open access approach may be employed, where an incision is made directly over the vessel to gain access.
  • Step 2: Inserting the Vascular Catheter - Once access is achieved, a vascular catheter is introduced over the guidewire. Contrast dye is injected through this catheter to visualize the vein and identify any areas of narrowing or disease. This imaging step is crucial for determining the extent of the obstruction.
  • Step 3: Advancing the Balloon Catheter - After the vascular catheter is positioned and imaging is complete, it is replaced with a balloon catheter. This catheter is carefully advanced to the site of the narrowing or obstruction within the vein.
  • Step 4: Inflating the Balloon - The balloon catheter is inflated with a dilute contrast dye, which expands the vessel at the site of the blockage. This inflation is maintained for a prescribed period to effectively open the narrowed area.
  • Step 5: Deflating and Removing the Balloon - Following the inflation period, the balloon is deflated and withdrawn from the vein. This step is critical to restore normal blood flow through the previously obstructed area.
  • Step 6: Re-evaluating the Vein - A vascular catheter is reinserted into the vein, and angiography is performed again to assess the success of the procedure. This imaging helps to determine if the vein has been adequately opened or if there is any residual stenosis that may require additional balloon inflation.

3. Post-Procedure

After the transluminal balloon angioplasty procedure, patients may require specific post-procedure care to ensure optimal recovery and monitor for any complications. This may include monitoring for signs of bleeding or infection at the access site, as well as assessing the patient's overall vascular status. Patients are typically advised to follow up with their healthcare provider to evaluate the success of the procedure and to determine if any further interventions are necessary. Additionally, instructions regarding activity restrictions and medication management may be provided to support recovery and prevent complications.

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.
RT Right side (used to identify procedures performed on the right side of the body)
AG Primary physician
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
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.
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).
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).
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.
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
