ANDREW MUNDWILER, MD appears in the CMS NPPES registry as a Neuromuscular Medicine (Psychiatry & Neurology) Physician provider holding MD credentials at 25 MICHIGAN ST NE, GRAND RAPIDS, MI, 49503, with a listed phone of (616) 267-7900. NPI 1265725147 was issued on 05/25/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MUNDWILER 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 789 prescription claims written by this provider, covering 139 Medicare beneficiaries and totaling roughly $582K in drug spend, split 7% brand-name and 93% generic by claim count, with an opioid prescribing rate of 2.7%. 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 100/100 for the 2023 performance year (Quality 87.5432), compared with the national average of 83.1.

Neuromuscular Medicine (Psychiatry & Neurology) Physician is a narrow specialty nationwide, with 336 enrolled providers across 44 states and an average of 931 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
