JONATHAN KOST, M.D. appears in the CMS NPPES registry as a Interventional Pain Medicine Physician provider holding M.D. credentials at 65 MEMORIAL RD, WEST HARTFORD, CT, 06107, with a listed phone of (860) 696-2843. NPI 1346274792 was issued on 07/10/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KOST 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 1,537 prescription claims written by this provider, covering 308 Medicare beneficiaries and totaling roughly $396K in drug spend, split 25% brand-name and 75% generic by claim count, with an opioid prescribing rate of 53.0%. 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 72.2238/100 for the 2023 performance year (Quality 99.2533, Cost 85.5926), compared with the national average of 83.1.

Interventional Pain Medicine Physician is a narrow specialty nationwide, with 1,528 enrolled providers across 53 states and an average of 2,197 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.
