Official Description

Percutaneous transcatheter closure of congenital interatrial communication (ie, Fontan fenestration, atrial septal defect) with implant

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 93580 involves a percutaneous transcatheter closure of congenital interatrial communication, which refers to an abnormal connection between the left and right atria of the heart. This condition can manifest as an atrial septal defect (ASD), a common congenital heart defect where there is a hole in the wall (septum) that separates the two atria. Additionally, this procedure can be utilized for the closure of Fontan fenestrations, which are intentional openings created during previous surgical procedures to improve blood flow in patients with complex congenital heart defects. The closure of these defects is critical as they can lead to complications such as heart failure, arrhythmias, and increased risk of stroke. The procedure is performed using an implant, which is a device designed to occlude the defect effectively. The approach is minimally invasive, typically involving access through the femoral artery, allowing for a quicker recovery and reduced risk compared to traditional open-heart surgery. The use of imaging techniques, such as echocardiography and angiography, ensures accurate placement of the implant and assessment of the defect before and after closure.

1. Indications

The percutaneous transcatheter closure of congenital interatrial communication is indicated for the following conditions:

  • Atrial Septal Defect (ASD) - A congenital defect characterized by an opening in the atrial septum, allowing blood to flow between the left and right atria.
  • Fontan Fenestration - A surgically created opening in patients who have undergone the Fontan procedure, which may require closure to improve hemodynamics.
  • Leaks in Surgically Created Baffles or Patches - Situations where there is an unintended connection or leak in the baffles or patches used in previous cardiac surgeries, necessitating closure to restore normal blood flow.

2. Procedure

The procedure for percutaneous transcatheter closure of congenital interatrial communication involves several critical steps:

  • Access Preparation - The skin over the access artery, typically one of the femoral arteries, is cleaned and prepped to minimize the risk of infection. A needle is then used to puncture the artery, and a sheath is placed to facilitate the introduction of other instruments.
  • Guidewire Insertion - A guidewire is inserted through the sheath and advanced through the access artery, traveling through the aorta and into the heart. This guidewire serves as a pathway for subsequent catheter placement.
  • Catheter Advancement - A catheter is advanced over the guidewire into the right atrium. This step may involve performing a right heart catheterization, and if necessary, a left heart catheterization through the existing septal opening to assess the defect.
  • Contrast Injection and Angiography - Contrast material is injected through the catheter, and angiography is performed to visualize the atrial septal defect. This imaging is crucial for determining the size and location of the defect.
  • Catheter Positioning - The catheter is maneuvered from the right atrium across the atrial septal defect into the left atrium, and further advanced into the upper pulmonary vein to facilitate the closure process.
  • Sizing Balloon Exchange - After the diagnostic phase, the initial catheter is exchanged for a sizing balloon, which is positioned across the defect and inflated. This inflation helps to measure the stretched diameter of the defect accurately.
  • Pressure and Saturation Assessment - Intracardiac pressures and oxygen saturation levels may be obtained while occluding the defect to ensure that the closure will be well-tolerated by the patient.
  • Dilator Placement - The sizing balloon is then exchanged for a dilator, which is advanced over the guidewire and positioned in the left atrium, preparing for the implant placement.
  • Implant Device Positioning - The implant device is carefully positioned within the defect. The placement is verified using echocardiography, which is a separate reportable procedure.
  • Implant Deployment - Once the position of the implant is confirmed, it is deployed to occlude the defect. The final position of the implant is again checked using echocardiography and/or angiography to ensure proper placement and function.

3. Post-Procedure

After the procedure, patients are typically monitored for any immediate complications, such as bleeding or arrhythmias. Recovery may involve a short hospital stay, during which the patient's heart function and the position of the implant are assessed. Follow-up echocardiograms may be scheduled to evaluate the success of the closure and to ensure that there are no residual defects or complications. Patients are usually advised on activity restrictions and follow-up care to promote optimal recovery and heart health.

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).
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.
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.
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.
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.
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).
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).
