MARY BORDNER, ACNP appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding ACNP credentials at 621 S NEW BALLAS RD STE 560A, SAINT LOUIS, MO, 63141, with a listed phone of (314) 251-6440. NPI 1437526126 was issued on 08/28/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BORDNER 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 136 prescription claims written by this provider, covering 38 Medicare beneficiaries and totaling roughly $31K in drug spend, split 29% brand-name and 71% 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.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
