When is authorization required for HCPCS/ CPT codes 20610 and 20611?

Practices are only required to seek authorization for these codes (20610, 20611) when associated with Viscosupplementation therapy of the knee*/ injection of any hyaluronic acid product. When submitting the authorization request, include codes 20610 or 20611 in addition to the J-code for the product being injected (e.g. Orthovisc: J7324 or Monovisc: J7327).

Authorization IS NOT REQUIRED for 20610 or 20611 when used in conjunction with any procedure other than viscosupplementation (e.g., corticosteroid injection, joint space aspiration).
