Pre-authorization required

Prior approval may be granted for E494 or E495 in patients with Kellgren-Lawrence grade 3 or 4 osteoarthritis (see Kohn MD, Sassoon AA, Fernando ND. Classifications in brief: Kellgren-Lawrence classification of osteoarthritis. Clin Orthop Relat Res. 2016 Aug; 474(8):1886-93) if the clinical record supports: a. Significant functional impairment caused by an unstable articular chondral flap or degenerative meniscal tear which has not responded to a minimum of six months active non-surgical treatment; and b. the patient is not a current candidate for knee realignment or arthroplasty.
