Florida Subscriber Answer: Modifier -52 tells the payer that you performed a particular service as described in the code but that the physician eliminated some portion of it. "This provides a way of reporting reduced services without disturbing the identification of the basic service," according to CPT. When you submit your claim with -52, the payer will assume that the price submitted is your full price and will reduce it. If you submit the claim at an already-reduced price, you will be costing your office money because the payer will likely reduce it even more.
