SHERRY COFFIELD, APN appears in the CMS NPPES registry as a Adult Health Clinical Nurse Specialist provider holding APN credentials at 1940 ALCOA HWY, KNOXVILLE, TN, 37920, with a listed phone of (865) 305-6810. NPI 1750552014 was issued on 03/14/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what COFFIELD 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 1,909 prescription claims written by this provider, covering 348 Medicare beneficiaries and totaling roughly $181K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 2.5%. 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 95.6914/100 for the 2023 performance year (Quality 85.2885), compared with the national average of 83.1.

Adult Health Clinical Nurse Specialist is a narrow specialty nationwide, with 1,375 enrolled providers across 49 states and an average of 1,088 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.
