Summary
Blue Cross Blue Shield policy L.7.01.429 confirms that thermal capsulorrhaphy procedures for joint instability (including shoulder, knee, and elbow) are considered not medically necessary. Claims for these procedures using CPT 29999 and HCPCS S2300 will be denied.
Action Required
Immediately: Billing team must flag CPT 29999 (unlisted arthroscopy) and HCPCS S2300 (thermal capsulorrhaphy) as non-covered for BCBS plans when used for joint instability. Update billing system to alert staff that these procedures are considered not medically necessary. Advise providers to use alternative covered procedures for shoulder, knee, and elbow instability treatment.
