DEMOSTHENES ASUNCION, MD appears in the CMS NPPES registry as a Emergency Medicine Physician provider holding MD credentials at 15 SENECA TRL, PANA, IL, 62557, with a listed phone of (217) 562-4470. NPI 1639192024 was issued on 07/26/2006.

Medicare Part D records for calendar year 2023 show 257 prescription claims written by this provider, covering 130 Medicare beneficiaries and totaling roughly $12K in drug spend, with an opioid prescribing rate of 9.3%. 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 95.012/100 for the 2023 performance year (Quality 80.0239), compared with the national average of 83.1.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,398 enrolled providers across 56 states and an average of 352 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.
