SHERMAN WIENEKE, AGNP appears in the CMS NPPES registry as a Emergency Registered Nurse provider holding AGNP credentials at 4502 MEDICAL DR, SAN ANTONIO, TX, 78229, with a listed phone of (210) 358-8555. NPI 1275088031 was issued on 08/22/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WIENEKE 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 125 prescription claims written by this provider, covering 65 Medicare beneficiaries and totaling roughly $6K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 10.4%. 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.

Emergency Registered Nurse is a narrow specialty nationwide, with 4,284 enrolled providers across 54 states and an average of 710 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.
