LOUISE DEWEY, R.N., PMHNP-BC appears in the CMS NPPES registry as a Psychiatric/Mental Health Nurse Practitioner provider holding R.N., PMHNP-BC credentials at 605 E 7TH AVE, SAULT SAINTE MARIE, MI, 49783, with a listed phone of (906) 440-2272. NPI 1407945132 was issued on 10/12/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DEWEY 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 2,807 prescription claims written by this provider, covering 91 Medicare beneficiaries and totaling roughly $250K in drug spend, split 6% brand-name and 94% 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 87.2245/100 for the 2023 performance year (Quality 86.5899), compared with the national average of 83.1.

Psychiatric/Mental Health Nurse Practitioner is a mid-sized specialty nationwide, with 39,953 enrolled providers across 54 states and an average of 927 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.
