Common Language Description

Transluminal balloon angioplasty is a specialized endovascular procedure designed to treat narrowing or blockage (stenosis) in various arteries, excluding those in the lower extremities. This procedure employs fluoroscopy, a type of real-time imaging, to visualize the arteries and guide the treatment process. The procedure can be performed either percutaneously or through an open approach. In the percutaneous method, a needle is inserted through the skin into a blood vessel, typically located in the groin, arm, or neck. A guidewire is then threaded through this needle, which is subsequently replaced with a vascular sheath to facilitate the introduction of a catheter. In contrast, the open approach involves making an incision directly over the targeted vessel to gain access. Once access is achieved, a vascular catheter is inserted over the guidewire, and contrast dye is injected to enhance the visibility of the arteries and pinpoint areas of stenosis or occlusion. Following this, the vascular catheter is exchanged for a balloon catheter, which is carefully advanced to the site of narrowing. The balloon is inflated with a dilute contrast solution, effectively expanding the artery for a specified duration. After the inflation period, the balloon is deflated and removed. To confirm the success of the procedure, a vascular catheter is reinserted, and angiography is performed again to assess whether the artery has been adequately opened or if further intervention is necessary. The CPT® Code 37246 is used to report the initial angioplasty performed on the first artery, while CPT® Code 37247 is designated for each additional artery treated during the same session.

1. Indications

The indications for performing transluminal balloon angioplasty include the following conditions:

  • Occlusive Disease - This procedure is indicated for patients with occlusive disease affecting arteries other than the lower extremities, which may lead to reduced blood flow and associated symptoms.
  • Intracranial Stenosis - Patients with narrowing of the arteries supplying the brain may benefit from this procedure to restore adequate blood flow and prevent complications such as stroke.
  • Coronary Artery Disease - Individuals with narrowed coronary arteries may undergo this procedure to alleviate symptoms of angina and reduce the risk of myocardial infarction.
  • Pulmonary Artery Stenosis - This procedure can be indicated for patients with narrowed pulmonary arteries, which can lead to compromised oxygenation and respiratory issues.
  • Dialysis Circuit Issues - Patients requiring dialysis may have stenosis in their dialysis access circuit, making this procedure necessary to maintain adequate blood flow for effective dialysis treatment.

2. Procedure

The procedure for transluminal balloon angioplasty involves several critical steps, which are detailed as follows:

  • Accessing the Artery - The procedure begins with the selection of an appropriate access site, typically in the groin, arm, or neck. For percutaneous access, a needle is inserted through the skin into the chosen vessel. A guidewire is then threaded through the needle, which is subsequently removed and replaced with a vascular sheath to facilitate catheter insertion. In cases where an open approach is necessary, an incision is made over the targeted vessel, allowing direct access to the artery.
  • 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 artery and identify any areas of stenosis or occlusion. This imaging step is crucial for determining the exact location and severity of the blockage.
  • Balloon Catheter Advancement - After identifying the narrowed area, the vascular catheter is exchanged for a balloon catheter. This balloon catheter is carefully advanced to the site of stenosis, ensuring precise placement for effective treatment.
  • Balloon Inflation - The balloon is then inflated with a dilute contrast solution, which expands the artery at the site of narrowing. This inflation is maintained for a prescribed duration to ensure adequate dilation of the vessel.
  • Deflation and Evaluation - Following the inflation period, the balloon is deflated and withdrawn from the artery. A vascular catheter is reinserted to perform angiography again, allowing the physician to evaluate the success of the procedure by assessing the patency of the artery and checking for any residual stenosis that may require further balloon inflation.

3. Post-Procedure

Post-procedure care for patients undergoing transluminal balloon angioplasty typically includes monitoring for any complications, such as bleeding or vascular access site issues. Patients may be observed for a period to ensure stable vital signs and adequate blood flow. Follow-up imaging may be necessary to confirm the success of the procedure and to assess for any potential re-narrowing of the treated artery. Additionally, patients may receive instructions regarding activity restrictions and medication management to support recovery and prevent future vascular issues.

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).
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.
