TAMARA HARRIS, APRN appears in the CMS NPPES registry as a Acute Care Clinical Nurse Specialist provider holding APRN credentials at 3400 NW EXPRESSWAY STE 200, OKLAHOMA CITY, OK, 73112, with a listed phone of (405) 713-9900. NPI 1477193217 was issued on 01/09/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HARRIS 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 2,799 prescription claims written by this provider, covering 438 Medicare beneficiaries and totaling roughly $418K in drug spend. 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 89.8603/100 for the 2023 performance year (Quality 83.6335, Cost 65.9009), compared with the national average of 83.1.

Acute Care Clinical Nurse Specialist is a narrow specialty nationwide, with 510 enrolled providers across 47 states and an average of 773 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.
