BENJAMIN CHACK, D.O. appears in the CMS NPPES registry as a Plastic Surgery within the Head & Neck (Otolaryngology) Physician provider holding D.O. credentials at 3 CORNERSTONE DRIVE, LANGHORNE, PA, 19047, with a listed phone of (267) 689-1000. NPI 1649265752 was issued on 09/14/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHACK 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 19 prescription claims written by this provider, covering 17 Medicare beneficiaries and totaling roughly $251 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.

Plastic Surgery within the Head & Neck (Otolaryngology) Physician is a narrow specialty nationwide, with 608 enrolled providers across 48 states and an average of 379 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.
