Coverage Determination

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.

Not medically necessary / Investigational

Covered when ALL of the following are met

Primary coverage determination: Surgical ventricular restoration is investigational for treatment of ischemic dilated cardiomyopathy and is not supported as medically necessary based on current evidence.n/a

Evidence includes a large randomized controlled trial (STICH) that did not demonstrate significant improvements in quality-of-life outcomes when SVR was added to CABG; uncontrolled studies are lower-quality and do not establish net health benefit.

The evidence base includes a large randomized controlled trial (the STICH trial), a second smaller RCT with overlapping enrollment, and uncontrolled observational studies. The randomized evidence did not demonstrate significant improvements in quality of life when SVR was added to coronary artery bypass grafting (CABG), and uncontrolled studies provide only lower-quality hemodynamic data. Overall, the evidence is insufficient to show an improvement in net health outcomes for SVR as an adjunct to CABG in ischemic dilated cardiomyopathy.

Provider Actions and Authorization

Prior Authorization

Inpatient precertification required

Precertification/preauthorization is required when the procedure is performed inpatient; obtain prior authorization before scheduling inpatient SVR.

Step Therapy

No step therapy specified

No step therapy or trial-of-therapy requirements are specified in this policy; the evidence summary indicates insufficient net health benefit when SVR is added to CABG.

Documentation Required

Coding and documentation guidance

Report all services using the most up-to-date industry-standard procedure, revenue, and diagnosis codes and include modifiers where applicable; inclusion of a code does not guarantee coverage and documentation should support medical necessity.

Use current CPT, revenue, and ICD diagnosis codes.
Include modifiers when applicable to reflect the performed service.

Denial Risk

Investigational procedure — denial risk

SVR is considered investigational for ischemic dilated cardiomyopathy; billing SVR for this indication may result in denial of coverage.

Policy states SVR is INVESTIGATIONAL for treatment of ischemic dilated cardiomyopathy.
RCT evidence did not show significant quality-of-life benefit when SVR was added to CABG.

Prior Authorization

Obtain precertification for inpatient services

Precertification/preauthorization is required for inpatient services; absence of prior authorization may trigger denial or administrative nonpayment.

Obtain prior authorization for inpatient SVR to avoid potential denial or nonpayment.

Background

Surgical ventricular restoration (SVR) is an operative procedure intended to restore or remodel the left ventricle toward a more normal, spherical shape and size in patients with akinetic or dyskinetic ventricular segments following myocardial infarction, commonly manifesting as ischemic dilated cardiomyopathy. The technique—also referred to as the Dor procedure or endoventricular circular plasty—uses circular suturing and sometimes patch reconstruction to isolate scar and reconstruct ventricular contour. SVR is frequently performed at the time of other cardiac procedures, most commonly coronary artery bypass grafting (CABG), and may be done in conjunction with mitral valve repair or replacement, endocardectomy, or other adjunctive procedures such as cryoablation.

Definitions

Surgical ventricular restoration (SVR) — definition and alternative names

Primary termSurgical ventricular restoration (SVR)

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

Technique summaryUses circular 'purse string' suturing around border of aneurysmal scar to isolate akinetic or dyskinetic segments and restore ventricular contour; may include prosthetic or autologous patch when defect >3 cm

Typical clinical contextPerformed in patients after myocardial infarction with akinetic or dyskinetic segments, often in conjunction with CABG and possibly mitral valve procedures, endocardectomy, or cryoablation

Distinguishing featureDistinct from ventriculectomy/aneurysm removal and from partial left ventriculectomy; SVR specifically reapproximates healthy ventricular walls to restore normal contour
