Official Description

Percutaneous transcatheter closure of paravalvular leak; initial occlusion device, mitral valve

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 93590 involves the percutaneous transcatheter closure of a paravalvular leak (PVL) specifically at the mitral valve using an initial occlusion device. A paravalvular leak refers to a situation where there is an abnormal flow of blood around a prosthetic heart valve, which can occur when the seal between the prosthetic valve and the surrounding native tissue fails. This condition can lead to serious complications such as endocarditis, hemolytic anemia, and heart failure, necessitating intervention. The procedure is performed by inserting a vascular catheter through the femoral artery, which is then navigated to the heart. Depending on the approach—antegrade or retrograde—the catheter is maneuvered to access the mitral valve, allowing for the deployment of an occlusion device to effectively seal the leak. This minimally invasive technique is crucial for patients with PVLs, as it aims to restore proper hemodynamics and prevent further complications associated with the leak.

1. Indications

The percutaneous transcatheter closure of a paravalvular leak (PVL) at the mitral valve is indicated for patients who exhibit the following conditions:

  • Paravalvular Leak: The presence of a leak around a prosthetic mitral valve, which may lead to complications such as endocarditis, hemolytic anemia, or heart failure.

2. Procedure

The procedure for the percutaneous transcatheter closure of a paravalvular leak at the mitral valve involves several critical steps:

  • Step 1: A vascular catheter is introduced percutaneously through the femoral artery and advanced towards the heart. This initial access is crucial for navigating to the mitral valve.
  • Step 2: For the antegrade approach, the catheter is maneuvered into the left atrium, where a transseptal puncture is performed. This involves using a needle and sheath to create an opening between the left atrium and left ventricle.
  • Step 3: A guidewire is inserted through the sheath into the left ventricle, allowing the catheter to be advanced over the guidewire for further access.
  • Step 4: The initial guidewire is exchanged for a stiffer wire, which is then distally snared or exteriorized to create an arteriovenous loop, providing stability for the subsequent steps.
  • Step 5: The catheter is replaced with a delivery catheter that is inserted into the left ventricle, where the occlusion device is deployed to cover the paravalvular leak.
  • Step 6: The occlusion device may be retrieved and repositioned as necessary to ensure optimal placement and effectiveness.
  • Step 7: In the case of a retrograde approach, the catheter is passed from the left ventricle through the paravalvular leak and into the left atrium, where the occlusive device is placed similarly to the antegrade approach.
  • Step 8: If the leak is located at the aortic valve, the catheter is advanced to the ascending aorta and into the left ventricle, following the same device placement protocol as for the mitral valve.
  • Step 9: For small, round defects, a single occlusion device is typically sufficient, while larger, crescentic, or oblong defects may necessitate multiple devices. Additional occlusion devices can be delivered sequentially using a single catheter, or two guidewires/catheters may be employed to deploy them simultaneously.

3. Post-Procedure

Post-procedure care for patients undergoing percutaneous transcatheter closure of a paravalvular leak includes monitoring for any immediate complications, assessing the effectiveness of the occlusion device, and ensuring the patient's hemodynamic stability. Patients may require follow-up imaging studies to evaluate the closure of the leak and to monitor for any potential recurrence or complications. Additionally, standard post-procedural care protocols should be followed, including managing access site care and monitoring for signs of infection or other adverse events.

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.
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).
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).
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.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
