The NPI date is when this clinician registered for a National Provider Identifier, the billing number used on health claims. It is not a license, graduation or board-certification date. NPIs were first issued in May 2005 and became required on claims in 2007–2008, so an early date usually means the clinician was already in practice before then. What an NPI is

Education and training

  • 1998Medical school: University of Kansas School of Med (Kc/Wich/Sal)
  • 2006Registered with an NPI (national billing number; not a license date) — NPIs began in 2005, so practice likely started earlier

Undergraduate school, residency, fellowship, licensing exams and board certification aren’t in public federal data. Board certification can be confirmed with the certifying board (ABMS member boards for MDs, AOA boards for DOs).

Specialties and state licenses

  • Orthopaedic Surgery Physician primary
    KS license 04-30753
  • Orthopaedic Trauma Physician
    KS license 04-30753

As reported to the NPI registry. To confirm a license is current, check the state medical board.
