ANDREW DEMERITT, O.D. appears in the CMS NPPES registry as a Optometrist provider holding O.D. credentials at 122 N WASHINGTON ST, OWOSSO, MI, 48867, with a listed phone of (989) 720-2020. NPI 1073869293 was issued on 07/25/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DEMERITT 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 152 prescription claims written by this provider, covering 52 Medicare beneficiaries and totaling roughly $29K in drug spend, split 43% brand-name and 57% generic by claim count. 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.

Optometrist is a high-volume specialty nationwide, with 60,463 enrolled providers across 56 states and an average of 257 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.
