ANDREW SIEVILA, RN, PMHCNS-BC, APNP appears in the CMS NPPES registry as a Adult Psychiatric/Mental Health Registered Nurse provider holding RN, PMHCNS-BC, APNP credentials at 2448 S 102ND ST, WEST ALLIS, WI, 53227, with a listed phone of (414) 539-3024. NPI 1932502325 was issued on 09/30/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SIEVILA 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 1,566 prescription claims written by this provider, covering 148 Medicare beneficiaries and totaling roughly $97K in drug spend, split 3% brand-name and 97% 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.

Adult Psychiatric/Mental Health Registered Nurse is a narrow specialty nationwide, with 4,591 enrolled providers across 52 states and an average of 1,143 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.
