ARETHA HENNESSEE, CERTIFIED REGISTERED appears in the CMS NPPES registry as a Registered Nurse provider holding CERTIFIED REGISTERED credentials at 200 E. 33RD STREET, BALTIMORE, MD, 21218, with a listed phone of (410) 554-4511. NPI 1417961731 was issued on 07/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HENNESSEE 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 3,128 prescription claims written by this provider, covering 346 Medicare beneficiaries and totaling roughly $2.4 million in drug spend, split 65% brand-name and 35% 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 80.1797/100 for the 2023 performance year (Quality 76.6904, Cost 53.4937), compared with the national average of 83.1.

Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 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.
