Anthem BCBS's Specific Approach to Total Knee Replacement
Applicable Policy
Anthem Surgery Policy SURG.00024 (Total Knee Arthroplasty)
How Anthem BCBS Typically Denies This
Anthem frequently requests documentation of validated outcome scores (WOMAC, KOOS) and questions whether the patient has tried a supervised exercise program specifically for knee OA.
Your Strategy for This Payer
If you have WOMAC or KOOS scores showing significant functional limitation, lead with those numbers. Anthem medical directors respond well to quantifiable functional impairment data.
Key Phrase to Use on the Call
"The patient's WOMAC score of [X] reflects severe functional limitation despite [months] of supervised physical therapy and pharmacologic management, meeting the functional impairment criteria under SURG.00024."
Building Your Medical Necessity Argument
Document bone-on-bone contact or severe joint space narrowing on weight-bearing X-ray
Show failure of 3+ months conservative treatment

Address pre-surgical optimization (BMI, A1c, smoking)
