ROXANNE WITTMAN, APRN appears in the CMS NPPES registry as a Emergency Registered Nurse provider holding APRN credentials at 1888 BOILING SPRINGS RD, BOILING SPRINGS, SC, 29316, with a listed phone of (864) 599-0920. NPI 1275018434 was issued on 10/03/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WITTMAN 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 42 prescription claims written by this provider, covering 36 Medicare beneficiaries and totaling roughly $883 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 77.4044/100 for the 2023 performance year (Quality 81.2452, Cost 59.065), compared with the national average of 83.1.

Emergency Registered Nurse is a narrow specialty nationwide, with 4,284 enrolled providers across 54 states and an average of 710 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.
