ROBERT SPARROW, MD appears in the CMS NPPES registry as a Hypertension Specialist Physician provider holding MD credentials at 420 NE GLEN OAK AVE STE 401, PEORIA, IL, 61603, with a listed phone of (309) 676-8123. NPI 1134259781 was issued on 03/06/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SPARROW 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 2,841 prescription claims written by this provider, covering 428 Medicare beneficiaries and totaling roughly $81K 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.

Hypertension Specialist Physician is a narrow specialty nationwide, with 40 enrolled providers across 20 states and an average of 2,136 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.
