What procedures does Dr. Gray perform?
According to Medicare billing data, Dr. Gray the Medicare record under this individual NPI shows mainly office visits and diagnostic testing. Hospital-based physicians usually have their procedural work billed by the facility rather than under their own number, so this is a floor on their practice, not a description of it.
