JILL WALLNER, M.D. appears in the CMS NPPES registry as a Adolescent Medicine (Family Medicine) Physician provider holding M.D. credentials at 58 W FIRST ST, CROSSVILLE, TN, 38555, with a listed phone of (931) 456-7992. NPI 1942357942 was issued on 01/04/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WALLNER 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 5,230 prescription claims written by this provider, covering 423 Medicare beneficiaries and totaling roughly $622K in drug spend, split 15% brand-name and 85% generic by claim count, with an opioid prescribing rate of 1.4%. 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 28.9149/100 for the 2023 performance year (Quality 0, Cost 96.3831), compared with the national average of 83.1.

Adolescent Medicine (Family Medicine) Physician is a narrow specialty nationwide, with 261 enrolled providers across 44 states and an average of 2,881 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.
