DAVID MERCER, ACNP appears in the CMS NPPES registry as a Wound Care Registered Nurse provider holding ACNP credentials at 680 PREDDY CREEK RD, BARBOURSVILLE, VA, 22923, with a listed phone of (434) 882-4950. NPI 1306020920 was issued on 12/18/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MERCER 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 3,300 prescription claims written by this provider, covering 195 Medicare beneficiaries and totaling roughly $133K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 18.3%. 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 27.9736/100 for the 2023 performance year (Quality 0, Cost 93.2454), compared with the national average of 83.1.

Wound Care Registered Nurse is a narrow specialty nationwide, with 602 enrolled providers across 54 states and an average of 1,085 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.
