MICHAEL O'BRIEN, DO appears in the CMS NPPES registry as a Acupuncturist provider holding DO credentials at 3073 WHITE MOUNTAIN HWY, NORTH CONWAY, NH, 03860, with a listed phone of (603) 356-5472. NPI 1043343056 was issued on 03/13/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what O'BRIEN 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 178 prescription claims written by this provider, covering 17 Medicare beneficiaries and totaling roughly $14K in drug spend, split 10% brand-name and 90% 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.

Acupuncturist is a mid-sized specialty nationwide, with 33,269 enrolled providers across 55 states and an average of 797 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.
