REZANNE KHALIL appears in the CMS NPPES registry as a Geriatric Medicine (Internal Medicine) Physician provider at 9000 FRANKLIN SQUARE DR, BALTIMORE, MD, 21237, with a listed phone of (443) 777-8300. NPI 1891105441 was issued on 05/05/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KHALIL 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 1,890 prescription claims written by this provider, covering 234 Medicare beneficiaries and totaling roughly $218K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 0.6%. 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.

Geriatric Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 4,161 enrolled providers across 52 states and an average of 4,450 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
