POLICY UPDATE CHANGES

Policy states thermal capsulorrhaphy is not covered / not medically necessary due to insufficient evidence and potential for harm.

Coverage Summary

Thermal capsulorrhaphy (thermal capsular shrinkage) is considered not covered / not medically necessary for the treatment of joint instability because the evidence is insufficient to demonstrate an improvement in net health outcome. This position applies to the shoulder (the primary joint studied) and to other joints proposed for the procedure, including the knee, elbow, and others.

The literature reports a lack of efficacy in comparative studies and case series with high rates of unsatisfactory results and complications. Notable safety concerns include reports of serious complications such as glenohumeral chondrolysis, supporting the conclusion that the procedure may confer net harm.

Medicare Advantage Plans

Thermal capsulorrhaphy coverage determination:

Thermal capsulorrhaphy is not covered as a treatment of joint instability, including, but not limited to the shoulder, knee, and elbow, because the evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

Commercial Products

Thermal capsulorrhaphy coverage determination:

Thermal capsulorrhaphy is considered not medically necessary as a treatment of joint instability, including, but not limited to the shoulder, knee, and elbow, because the evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

Provider Actions & Billing Impact

Billing Rule

Use unlisted CPT for non-shoulder joints

When performing thermal capsulorrhaphy in joints other than the shoulder (ankle, knee, hip, wrist, or elbow) report CPT 29999 Unlisted procedure, arthroscopy.

Denial Risk

Claims for thermal capsulorrhaphy (shoulder) will be denied or not covered

Claims billed with HCPCS S2300 (Arthroscopy, shoulder; with thermally-induced capsulorrhaphy) are not covered for Medicare Advantage Plans and are considered not medically necessary for Commercial Products and may be denied.

Background & Evidence Summary

Thermal capsulorrhaphy is an arthroscopic technique that applies thermal energy to collagen in the joint capsule or ligaments to shrink and tighten the capsule, with the aim of restoring capsular tension and reducing capsular volume.

Historically, laser energy was used to produce the thermal effect; radiofrequency probes are now more commonly employed. The procedure was developed as a technically simpler arthroscopic alternative to suture-based capsular tightening and has been primarily investigated for shoulder instability, including use with other arthroscopic repairs or as a standalone treatment for capsular laxity.

Available comparative studies do not support the procedure’s efficacy and case series report high rates of unsatisfactory outcomes and complications. Reported harms include serious complications such as glenohumeral chondrolysis and other adverse events, leading to the determination that the procedure is not medically necessary because of potential net harm.
