Medicare and federal program status
Opted out of Medicare from July 1, 2013 through July 1, 2027. Medicare does not pay for this clinician’s services: patients with Medicare sign a private contract and pay the clinician directly. They can still order tests and refer Medicare patients to other providers.
Source: CMS Medicare Opt Out Affidavits (record last updated August 15, 2025). Opting out is a legal choice many clinicians make, often to run a cash or concierge practice.
At a glance
- In the NPI registry since
- 2007
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
- 2007Registered with an NPI (national billing number; not a license date) — NPIs began in 2005, so practice likely started earlier
Medicare’s Care Compare data doesn’t list this clinician’s medical school. Undergraduate school, residency, fellowship, licensing exams and board certification aren’t in public federal data.
