Does Aetna cover knee arthroscopy?
Knee arthroscopy is covered when there is a specific, identifiable mechanical problem: meniscus tear, loose bodies, or ACL/PCL injury. Coverage for arthroscopy for osteoarthritis alone (without a discrete mechanical problem) is significantly restricted after landmark studies showed no benefit over sham surgery for that indication. An MRI identifying specific structural pathology is the key prior authorization document.

Prior authorization for Aetna
Aetna covers standard orthopedic care: evaluations, imaging, conservative treatment, and surgery. They use a Centers of Excellence program for complex procedures like spinal fusion and joint replacement, where members may pay less when using a designated facility. PPO members can self-refer to specialists. HMO members go through their primary care doctor first. Prior authorization is required for most surgical procedures.
Always verify your specific Aetna plan before scheduling. Plans within the same insurer (Aetna) can have different prior authorization rules, network requirements, and cost-sharing. Call the number on the back of your insurance card or log into your plan portal to confirm coverage for your specific plan.
How to confirm your coverage before scheduling
- 1Call Aetna member services (number on back of your insurance card) and ask specifically if knee arthroscopy is covered under your plan.
- 2Ask your orthopedic surgeon's office to verify benefits on your behalf - they do this routinely and can identify in-network requirements.
- 3Request the prior authorization criteria in writing if prior auth is required. Ask what documentation is needed from your surgeon.
- 4Confirm your deductible remaining for the year - your out-of-pocket cost depends on where you are in the deductible cycle.
- 5Get a pre-service cost estimate from the facility if you want a specific dollar figure before scheduling.
What to do if Aetna denies coverage
Insurance denials for orthopedic procedures are common and frequently overturned on appeal. Follow these steps:
- 1Ensure MRI report clearly identifies the specific mechanical problem (meniscus tear, loose body, etc.)
- 2Avoid framing the indication as arthritis alone - document the discrete mechanical pathology
- 3Provide clinical notes describing mechanical symptoms (locking, catching, effusion)
