MATTHEW DEWYS, DO appears in the CMS NPPES registry as a Emergency Medical Services (Emergency Medicine) Physician provider holding DO credentials at 615 S BOWER ST, GREENVILLE, MI, 48838, with a listed phone of (616) 754-4341. NPI 1427151083 was issued on 09/07/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DEWYS 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 240 prescription claims written by this provider, covering 172 Medicare beneficiaries and totaling roughly $5K in drug spend, with an opioid prescribing rate of 7.9%. 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 48.0992/100 for the 2023 performance year (Quality 0), compared with the national average of 83.1.

Emergency Medical Services (Emergency Medicine) Physician is a narrow specialty nationwide, with 3,616 enrolled providers across 55 states and an average of 394 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.
