One of the surgeons I bill for dispenses L1833 knee braces to some of his outpatient surgery patients. United Healthcare commercial plan used to pay for these braces, but around April 2018, it stopped paying and started denying the braces as part of the global service. I called and spoke to a rep about a policy change. She denied any knowledge of a change in policy and suggested I do a reconsideration. UHC denied the reconsideration stating the claim was paid correctly. Does anyone have any advice they can share? Thank you.
