MARK BIAGTAN appears in the CMS NPPES registry as a Pediatrics Physician provider at 20 S PARK ST, MADISON, WI, 53715, with a listed phone of (608) 287-2600. NPI 1376707307 was issued on 07/18/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BIAGTAN 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 3,485 prescription claims written by this provider, covering 492 Medicare beneficiaries and totaling roughly $976K in drug spend, split 54% brand-name and 46% 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.

Pediatrics Physician is a high-volume specialty nationwide, with 80,574 enrolled providers across 56 states and an average of 762 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
