SOURAYA EL-SAYED ABDALLAH appears in the CMS NPPES registry as a Ambulatory Care Pharmacist provider at 13415 CONNECTICUT AVE STE 100, SILVER SPRING, MD, 20906, with a listed phone of (301) 557-1950. NPI 1326817958 was issued on 12/22/2023. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what EL-SAYED ABDALLAH 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Ambulatory Care Pharmacist providers operate outside Part D entirely.

Ambulatory Care Pharmacist is a narrow specialty nationwide, with 3,473 enrolled providers across 52 states and an average of 492 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.
