SHANNON BIERIG, APRN-CNP, CNS appears in the CMS NPPES registry as a Acute Care Clinical Nurse Specialist provider holding APRN-CNP, CNS credentials at 275 S PERKINS RD, STILLWATER, OK, 74074, with a listed phone of (405) 334-5272. NPI 1386947570 was issued on 12/10/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BIERIG 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 510 prescription claims written by this provider, covering 271 Medicare beneficiaries and totaling roughly $7K 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.

Acute Care Clinical Nurse Specialist is a narrow specialty nationwide, with 510 enrolled providers across 47 states and an average of 773 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.
