REGINA NAGARAJAN, M.D. appears in the CMS NPPES registry as a Psychiatry Physician provider holding M.D. credentials at 115 KILDAIRE PARK DR STE 402, CARY, NC, 27518, with a listed phone of (919) 443-4100. NPI 1174910566 was issued on 04/23/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NAGARAJAN 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 203 prescription claims written by this provider, covering 23 Medicare beneficiaries and totaling roughly $16K 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.

Psychiatry Physician is a high-volume specialty nationwide, with 53,104 enrolled providers across 56 states and an average of 1,038 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.
