UHC's Specific Approach to Total Knee Replacement
Applicable Policy
UHC Clinical UM Guideline CG-SURG-23 (Total Knee Arthroplasty)
How UHC Typically Denies This
UHC denies TKA most commonly for insufficient conservative management documentation or BMI >40 without documented optimization. They require weight-bearing X-rays showing Kellgren-Lawrence grade 3 or 4.
Your Strategy for This Payer
UHC wants to see bone-on-bone on weight-bearing films. If you only have non-weight-bearing X-rays, that's often the gap. Address BMI optimization directly -- even if the patient hasn't reached goal, document the effort.
Key Phrase to Use on the Call
"Weight-bearing radiographs demonstrate Kellgren-Lawrence grade [3/4] with [bone-on-bone contact/severe joint space narrowing], and the patient has completed [X months] of conservative management including [specific treatments] per CG-SURG-23."
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
Use validated outcome scores (WOMAC, KOOS)
Address pre-surgical optimization (BMI, A1c, smoking)
