JOHN BOSWORTH, RPA appears in the CMS NPPES registry as a Medical Physician Assistant provider holding RPA credentials at 4904 19TH AVE, ASTORIA, NY, 11105, with a listed phone of (718) 777-3494. NPI 1780814947 was issued on 07/22/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BOSWORTH 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 239 prescription claims written by this provider, covering 42 Medicare beneficiaries and totaling roughly $25K in drug spend, with an opioid prescribing rate of 8.8%. 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.

Medical Physician Assistant is a mid-sized specialty nationwide, with 40,527 enrolled providers across 55 states and an average of 1,077 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.
