MARCIA RING, PHD, ARNP appears in the CMS NPPES registry as a Adult Psychiatric/Mental Health Clinical Nurse Specialist provider holding PHD, ARNP credentials at 510 OXFORD WAY, MARTINSBURG, WV, 25405, with a listed phone of (641) 863-0774. NPI 1992724264 was issued on 07/18/2006.

Medicare Part D records for calendar year 2023 show 288 prescription claims written by this provider, covering 29 Medicare beneficiaries and totaling roughly $13K 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 94.1061/100 for the 2023 performance year (Quality 78.4655), compared with the national average of 83.1.

Adult Psychiatric/Mental Health Clinical Nurse Specialist is a narrow specialty nationwide, with 953 enrolled providers across 51 states and an average of 1,309 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.
