PHILLIP EXUM, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 8901 ROCKVILLE PIKE, BETHESDA, MD, 20889, with a listed phone of (301) 295-4000. NPI 1942586300 was issued on 10/31/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what EXUM 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 22 prescription claims written by this provider, covering 19 Medicare beneficiaries and totaling roughly $154 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 79.5404/100 for the 2023 performance year (Quality 69.0256, Cost 65.2757), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 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.
