Corbin Sullivan, M.D. appears in the CMS NPPES registry as a Student in an Organized Health Care Education/Training Program provider holding M.D. credentials at 601 JOHN ST, Kalamazoo, MI, 49007, with a listed phone of (269) 381-0180. NPI 1225352792 was issued on 03/26/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Sullivan 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 368 prescription claims written by this provider, covering 164 Medicare beneficiaries and totaling roughly $9K in drug spend, with an opioid prescribing rate of 23.4%. 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 85.3/100 for the 2023 performance year (Quality 79.7, Cost 71.4), compared with the national average of 83.1.

Student in an Organized Health Care Education/Training Program is a high-volume specialty nationwide, with 331,761 enrolled providers across 55 states and an average of 459 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
