DARRYL WEIMAN, M.D. appears in the CMS NPPES registry as a Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician provider holding M.D. credentials at 10810 PARKSIDE DR STE 208, KNOXVILLE, TN, 37934, with a listed phone of (865) 647-3350. NPI 1558472043 was issued on 08/31/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WEIMAN 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 89.6389/100 for the 2023 performance year (Quality 77.663), compared with the national average of 83.1.

Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician is a mid-sized specialty nationwide, with 5,062 enrolled providers across 52 states and an average of 128 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.
