MICHAEL GUTHRIE, D.D.S. appears in the CMS NPPES registry as a Oral and Maxillofacial Pathology Dentistry provider holding D.D.S. credentials at 2300 S MICHIGAN AVE STE 100, CHICAGO, IL, 60616, with a listed phone of (872) 302-5322. NPI 1063504819 was issued on 09/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GUTHRIE 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 624 prescription claims written by this provider, covering 240 Medicare beneficiaries and totaling roughly $3K in drug spend, with an opioid prescribing rate of 27.7%. 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.

Oral and Maxillofacial Pathology Dentistry is a narrow specialty nationwide, with 690 enrolled providers across 48 states and an average of 303 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
