Question:
How do we know whether to put the NPP (PA or NP) or physician NPI number in box 24J on the claim form?
Answer:
When services are reported using the Direct billing method, the NPI of the provider performing the services places their NPI number in box 24J. When services are reported Incident-to, whether performed by an NPP or ancillary staff, box 24J should show the name of the supervising provider.
