Modifiers 26/TC


Best answers
I am trying to obtain information of how to bill for urodynamics that were performed by an NP, but interpreted by a physician on a separate date. Both providers are in the same practice, and own the equipment. Is it appropriate to bill for example:

51728,TC under the NP on the date the test was performed (04/02/16), and

51728,26 under the physician on the DOS he interpreted the test (04/04/2016).

This is not "incident to" as the physician is not in the suite when the test is performed. The NP has his own NPI to bill Medicare. I have been told in the past that 51728 should be billed w/ no modifiers since the providers are in the same practice and the service cannot be unbundled.

Any guidance is much appreciated.

Thank you!
