Philip Velderman, M.D. appears in the CMS NPPES registry as a Rheumatology Physician provider holding M.D. credentials at 577 MICHIGAN AVE STE 104, Holland, MI, 49423, with a listed phone of (616) 393-5336. NPI 1366401325 was issued on 03/20/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Velderman 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 2,059 prescription claims written by this provider, covering 349 Medicare beneficiaries and totaling roughly $1.9 million in drug spend, split 14% brand-name and 84% generic by claim count, with an opioid prescribing rate of 1.3%. 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.

Rheumatology Physician is a mid-sized specialty nationwide, with 6,181 enrolled providers across 52 states and an average of 2,054 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
