Michael Gerdis, MD appears in the CMS NPPES registry as a Internal Medicine Physician provider holding MD credentials at 2422 CENTRAL PARK AVE, Yonkers, NY, 10710, with a listed phone of (914) 779-2995. NPI 1871567925 was issued on 02/15/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Gerdis 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 3,580 prescription claims written by this provider, covering 504 Medicare beneficiaries and totaling roughly $191K in drug spend, split 6% brand-name and 94% generic by claim count. 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.

Internal Medicine Physician is a high-volume specialty nationwide, with 172,858 enrolled providers across 56 states and an average of 2,716 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
