Coverage Criteria

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Commercial Products - Medical Necessity Determination

SVR is considered not medically necessary for Commercial Products when used for ischemic dilated cardiomyopathy, including as an adjunct to CABG.

Overall policy stance: Surgical ventricular restoration (SVR) is considered not medically necessary as the evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

Based on randomized trial evidence (including the STICH trial) showing no significant quality-of-life benefit when SVR is added to CABG and lower-quality uncontrolled studies reporting only hemodynamic improvements.

This policy applies to Commercial Products only. Medicare Advantage Plans are addressed separately; see the related Medicare Advantage Plans National and Local Coverage Determinations policy for applicable guidance.

For Commercial Products, surgical ventricular restoration (CPT 33548) is considered not medically necessary. Claims for this procedure may be denied because the evidence is insufficient to demonstrate an improvement in net health outcome when SVR is performed (including as an adjunct to CABG).

Background

Surgical ventricular restoration (SVR) is an operative technique intended to remodel the left ventricle toward a more normal, spherical shape and size in patients with akinetic or dyskinetic segments following myocardial infarction. Procedures include variants such as the Dor and SAVER techniques, which may use circular suturing and sometimes prosthetic patches to isolate scar and restore ventricular contour, and are frequently performed in conjunction with coronary artery bypass grafting and occasionally with mitral valve procedures.

Device components used in SVR (for example, intracardiac patches) are regulated by the U.S. Food and Drug Administration, typically through the 510(k) clearance process; investigational or transcatheter systems (eg, AccuCinch, Revivent) remain under study.

Evidence includes a large randomized controlled trial (STICH) and other uncontrolled studies; while uncontrolled reports show hemodynamic improvements, higher-quality randomized data did not demonstrate a quality-of-life benefit when SVR was added to CABG, supporting the policy determination for Commercial Products.

Definitions

Surgical ventricular restoration (SVR) — alternate names and brief definition

Alternate namesSurgical anterior ventricular endocardial restoration; left ventricular reconstructive surgery; endoventricular circular plasty; Dor procedure

Brief definitionAn operation to remodel the left ventricle by isolating akinetic or dyskinetic scar with circular 'purse string' suturing (and sometimes using patches for large defects) to restore a more normal ventricular contour and volume.

Typical clinical contextUsually performed after CABG and may be combined with mitral valve repair/replacement, endocardectomy, or cryoablation for ventricular tachycardia.

Surgical technique noteIf the ventricular defect is >3 cm, reconstruction may use autologous or artificial patches to maintain desired volume and contour during closure of the ventriculotomy.

Distinguishing featureUnlike ventriculectomy or partial left ventriculectomy (Batista), SVR uses circular suturing to restore ventricular contour rather than simple resection.

Intracardiac patch devices — examples and regulatory class information

Regulatory classificationClass II devices regulated via the FDA 510(k) clearance process for intracardiac repair/patching.

Common patch materialsPolypropylene, polyethylene terephthalate, polytetrafluoroethylene, or biological (eg, glutaraldehyde-fixed bovine pericardium).

Example cleared deviceCorRestore Patch System (glutaraldehyde-fixed bovine pericardial patch with integral suture bolster) — cleared by FDA for intracardiac reconstruction and repair (2004).

Investigational systemsAccuCinch ventricular restoration system (FDA investigational device exemption received 2020) and Revivent System (pivotal RELIVE trial enrollment reported; previously FDA Breakthrough Device Designation).
