ZACHARY RICHENS, DO appears in the CMS NPPES registry as a Sleep Medicine (Family Medicine) Physician provider holding DO credentials at 3200 W CENTRE AVE STE 203, PORTAGE, MI, 49024, with a listed phone of (269) 349-9745. NPI 1912404807 was issued on 04/09/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what RICHENS 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 339 prescription claims written by this provider, covering 79 Medicare beneficiaries and totaling roughly $277K in drug spend, split 8% brand-name and 92% generic by claim count, with an opioid prescribing rate of 5.3%. 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 84.8851/100 for the 2023 performance year (Quality 81.2912, Cost 68.3258), compared with the national average of 83.1.

Sleep Medicine (Family Medicine) Physician is a narrow specialty nationwide, with 190 enrolled providers across 45 states and an average of 1,506 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.
