CPT Code 93580: Percutaneous Transcatheter Closure of Congenital Interatrial Communication

CPT code 93580 documentation requirements

Accurate and thorough documentation is essential to support the use of CPT Code 93580 for the percutaneous transcatheter closure of a congenital interatrial communication, such as an atrial septal defect (ASD) or Fontan fenestration. The following key elements should be clearly included in the medical record:

• Detailed procedural description, outlining each step—catheter insertion, imaging techniques, and closure of congenital interatrial defects via implantable devices.
• Device specifications, including the type, size, and manufacturer of the closure implant (e.g., FDA-approved device) used in the septal defect ASD closure.
• Pre- and post-procedure diagnostic findings, such as echocardiography, angiography, and hemodynamic measurements, that confirm septal defect type, size, and procedural success in PFO closure or atrial septal correction.
• Medical necessity justification, including relevant diagnosis, clinical history (e.g., atrial fibrillation, heart failure), symptomatology, and rationale for selecting a transcatheter closure of congenital interatrial communication, i.e, Fontan.
• Intra-procedural data, including documentation of oxygen saturations, pressure gradients, and imaging modalities used (e.g., fluoroscopy, intracardiac echocardiography).
• Any complications or additional interventions performed during the procedure (e.g., conversion to cardiopulmonary bypass if needed).
• Attestation of provider qualifications, confirming that the procedure was performed by a physician with appropriate training and expertise in percutaneous transcatheter closure procedures.

CPT code 93580 billing guidelines

Billing for CPT code 93580 requires careful attention to settings, component coding, modifiers, and payer-specific rules. The following are updated billing guidelines:

• CPT 93580 is typically performed in an inpatient or outpatient cardiac catheterization lab. However, some payers may designate this as an inpatient-only procedure, so providers must check the payer’s coverage policy or CMS inpatient-only list for compliance.
• CPT 93580 does not include diagnostic right/left heart catheterization (e.g., 93451, 93453) or separate angiography unless medically necessary and documented. These services may be reported separately if its performed for distinct clinical indications, not considered part of the procedural work, and supported with appropriate documentation.
• Do not report CPT 93662 (intracardiac echocardiography) separately if used solely to guide the closure procedure, as it is considered bundled into 93580. It may be reported separately only if used for diagnostic purposes beyond procedural guidance.

Use modifiers such as:

• Modifier -26: Use to bill the professional component only (e.g., in hospital settings).
• Modifier -59: May be used to indicate a distinct procedural service, such as separately reportable catheterization or imaging, when justified and supported.
• Modifier -51: May apply when multiple procedures are performed during the same session, subject to payer-specific bundling rules.

Other relevant CPT codes

• 93581: Percutaneous transcatheter closure of other acquired or complex cardiac defects, such as post-infarction ventricular septal defects or traumatic septal defects.
• 33208: Transvenous insertion of a permanent dual-chamber pacemaker, when performed concurrently with defect closure (only when clinically indicated and documented).
• 93451–93461: Right and left heart catheterization and related studies, billable separately if not included in the closure procedure and deemed medically necessary.
