Electrothermal Arthroscopy

Aetna considers electrothermal arthroscopy (ETAC) experimental and investigational and therefore not covered for any indication — including adhesive capsulitis/frozen shoulder, Achilles injuries/tendinitis, glenohumeral instability (Bankart, Hill‑Sachs), knee ligament/meniscal injuries, thumb/wrist/ankle injuries, TMJ dislocation, and related codes (HCPCS S2300 and applicable CPT/ICD‑10 codes) — unless there is explicit adequate evidence of long‑term effectiveness. No specific documentation requirements are stated in the policy.
