Aetna Total Ankle Arthroplasty coverage criteria

Aetna covers total ankle arthroplasty (TAA) with an FDA-cleared implant for skeletally mature members who have severe, imaging-confirmed ankle arthritis (osteoarthritis, post-traumatic, rheumatoid, or inflammatory) with moderate-to-severe pain and loss of function, only after failing at least 6 months of conservative management (PT, NSAIDs, orthoses) and only if none of a long list of contraindications (e.g., active infection, Charcot joint, avascular necrosis, vascular insufficiency, poor bone quality) are present; diabetics must have HbA1c under 8%. Revision TAA is covered for a failed prosthesis. Total talar replacement, trans-fibular TAA, custom implants, and several adjunct techniques are considered experimental/investigational, and TAA for any other indication is not established.

When does Aetna cover Total Ankle Arthroplasty (CPT 27702), and what gets it denied?

Path
Aetna covers total ankle arthroplasty (TAA) with an FDA-cleared implant for skeletally mature members who have severe, imaging-confirmed ankle arthritis (osteoarthritis, post-traumatic, rheumatoid, or inflammatory) with moderate-to-severe pain and loss of function, only after failing at least 6 months of conservative management (PT, NSAIDs, orthoses) and only if none of a long list of contraindications (e.g., active infection, Charcot joint, avascular necrosis, vascular insufficiency, poor bone quality) are present; diabetics must have HbA1c under 8%. Revision TAA is covered for a failed prosthesis. Total talar replacement, trans-fibular TAA, custom implants, and several adjunct techniques are considered experimental/investigational, and TAA for any other indication is not established. Coverage criteria include: Total ankle arthroplasty (TAA) using an FDA-cleared implant is considered medically necessary when ALL of the following criteria are met (criteria 1-7 below).; TAA is used to replace an arthritic or severely degenerated ankle.; Member is skeletally mature.; Member has moderate or severe pain with loss of ankle mobility and function.; Imaging is consistent with severe arthritis/degeneration of the ankle due to ONE of: osteoarthritis (degenerative arthritis) OR post-traumatic arthritis OR rheumatoid arthritis OR inflammatory arthritis.; Member has failed at least 6 months of conservative management, including physical therapy by a licensed physical therapist, non-steroidal anti-inflammatory drugs (NSAIDs), and orthoses as indicated.; Conservative-therapy detail: physical therapy must be in-person (not home or virtual), recent (within the past year), and for at least 6 weeks (12 weeks if age less than 50 years OR BMI greater than 40), confirmed by actual PT notes or by documentation in the member claims history. WAIVED/not required for severe osteoarthritis with bone-on-bone articulation in the weight-bearing portion of the joint (conservative therapy may be inappropriate in that case).; If member is diabetic, hemoglobin A1C (HbA1c) should be less than 8 percent within 3 months prior to surgery.; Member has NONE of the listed contraindications to TAA (all contraindications must be absent; see exclusions).; Revision TAA is considered medically necessary for individuals with a failed total ankle prosthesis.; FDA-cleared implants cited as examples: Agility LP Total Ankle, Eclipse Total Ankle, INBONE Total Ankle, Infinity Total Ankle System, STAR system, Salto Talaris Total Ankle Prosthesis, and Zimmer Trabecular Metal Total Ankle..
