Inserting tandem and ovoids


Q Our patient had tandems and ovoids (T&O) inserted by the same physician on April 30 and then again on May 7. Our claim-manager software indicated that we could not bill for both procedures because of the global period. Should we use the modifier -76 (repeat procedure by the same physician) to bill for the second T&O?

A You actually have 2 options in this case. The modifier -58 would be the modifier of choice if the second T&O insertion was planned at the time of the first insertion, i.e., a staged procedure. On the other hand, if the physician decided on a second insertion at some point after the first insertion, the modifier -76 would be the better code.
