ELIZABETH HOULIHAN, DNP FNP appears in the CMS NPPES registry as a Ambulatory Care Registered Nurse provider holding DNP FNP credentials at 2906 S 20TH ST, MILWAUKEE, WI, 53215, with a listed phone of (414) 672-1353. NPI 1982223707 was issued on 04/12/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HOULIHAN 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 17 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $602 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.

Ambulatory Care Registered Nurse is a narrow specialty nationwide, with 3,123 enrolled providers across 53 states and an average of 695 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.
