ALEXANDER KASS, OD appears in the CMS NPPES registry as a Optometric Assistant Technician provider holding OD credentials at 135 E 38TH ST, ERIE, PA, 16504, with a listed phone of (814) 868-8661. NPI 1336897081 was issued on 03/11/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KASS 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 15 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $966 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.

Optometric Assistant Technician is a narrow specialty nationwide, with 43 enrolled providers across 18 states and an average of 15 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.
