ADRIA TRAPANI-BARNACZ, APN, LPC, LCADC appears in the CMS NPPES registry as a Addiction (Substance Use Disorder) Counselor provider holding APN, LPC, LCADC credentials at 12 ROSZEL RD STE A103, PRINCETON, NJ, 08540, with a listed phone of (609) 419-0123. NPI 1831310309 was issued on 05/01/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TRAPANI-BARNACZ 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 871 prescription claims written by this provider, covering 73 Medicare beneficiaries and totaling roughly $159K in drug spend, split 10% brand-name and 90% 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.

Addiction (Substance Use Disorder) Counselor is a high-volume specialty nationwide, with 109,141 enrolled providers across 55 states and an average of 645 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.
