GREGORY JANSYN, DPM appears in the CMS NPPES registry as a Primary Podiatric Medicine Podiatrist provider holding DPM credentials at 303 E ARMY TRAIL RD, BLOOMINGDALE, IL, 60108, with a listed phone of (630) 893-3668. NPI 1639250632 was issued on 10/17/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JANSYN 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 26 prescription claims written by this provider, covering 17 Medicare beneficiaries and totaling roughly $628 in drug spend. 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.

Primary Podiatric Medicine Podiatrist is a narrow specialty nationwide, with 1,077 enrolled providers across 50 states and an average of 322 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.
