MARY MULLINS, DNP appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding DNP credentials at 211 E HARPOLE ST, WILLIAMSVILLE, IL, 62693, with a listed phone of (175) 889-8712. NPI 1912550468 was issued on 07/23/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MULLINS 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 48 prescription claims written by this provider, covering 41 Medicare beneficiaries and totaling roughly $364 in drug spend, with an opioid prescribing rate of 72.9%. 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 Health Nurse Practitioner is a mid-sized specialty nationwide, with 29,492 enrolled providers across 55 states and an average of 1,201 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
