Douglas Rau appears in the CMS NPPES registry as a Registered Nurse provider at 1900 WEALTHY ST SE STE 300, Grand Rapids, MI, 49506, with a listed phone of (616) 774-8345. NPI 1376085191 was issued on 11/10/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Rau 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 1,631 prescription claims written by this provider, covering 343 Medicare beneficiaries and totaling roughly $66K in drug spend, split <1% brand-name and >99% generic by claim count, with an opioid prescribing rate of 31.4%. 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 97.4/100 for the 2023 performance year (Quality 94.6), compared with the national average of 83.1.

Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
