Summary
This is a sources update to an existing policy that maintains thermal shrinkage for cruciate ligament injury as investigational (non-covered). The procedure uses unlisted CPT codes 27599 and 29999, meaning claims will be denied.
Action Required
No immediate action required. Continue denying/not billing thermal shrinkage procedures for ACL injuries using CPT 27599 and 29999 as these remain investigational and non-covered. If providers inquire about this procedure, confirm it is still considered investigational per updated policy sources.
