Yes, they can billed together.Multiple surgeries are separate procedures performed by a single physician or physicians in the same group practice on the same patient at the same operative session or on the same day for which separate payment may be allowed.Medicare pays for multiple surgeries by ranking from the highest MPFS amount to the lowest MPFS amount. When the same physician performs more than one surgical service at the same session, the allowed amount is 100 percent for the surgical code with the highest MPFS amount. The allowed amount for the subsequent surgical codes is based on 50 percent of the MPFS amount. In addition, special endoscopic pricing rules are applied prior to the multiple surgery rules, if applicable. Claims lines containing Modifier 22 are excluded from the multiple surgery payment methodology.
