NATALIE VASSAR, M.D. appears in the CMS NPPES registry as a Psychosomatic Medicine Physician provider holding M.D. credentials at 9410 S ELWOOD AVE STE 101, JENKS, OK, 74037, with a listed phone of (918) 401-0772. NPI 1346495124 was issued on 11/20/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what VASSAR most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 1,314 prescription claims written by this provider, covering 120 Medicare beneficiaries and totaling roughly $206K in drug spend, split 10% brand-name and 90% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 89.4019/100 for the 2023 performance year (Quality 76.2193, Cost 70.3454), compared with the national average of 83.1.

Psychosomatic Medicine Physician is a narrow specialty nationwide, with 491 enrolled providers across 43 states and an average of 645 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
