MATTHEW LIESEN, DMD appears in the CMS NPPES registry as a Public Health Dentistry provider holding DMD credentials at 4517 N ROCKWOOD DR, PEORIA, IL, 61615, with a listed phone of (309) 688-0121. NPI 1619350725 was issued on 07/07/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LIESEN 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 130 prescription claims written by this provider, covering 66 Medicare beneficiaries and totaling roughly $666 in drug spend, with an opioid prescribing rate of 18.5%. 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.

Public Health Dentistry is a narrow specialty nationwide, with 1,104 enrolled providers across 54 states and an average of 84 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.
