JEROME BARR, M.D. appears in the CMS NPPES registry as a Rheumatology Physician provider holding M.D. credentials at 17-15 MAPLE AVE, FAIR LAWN, NJ, 07410, with a listed phone of (201) 677-8759. NPI 1396914867 was issued on 02/28/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BARR 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 380 prescription claims written by this provider, covering 52 Medicare beneficiaries and totaling roughly $558K in drug spend, split 19% brand-name and 81% generic by claim count, with an opioid prescribing rate of 11.6%. 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.

Rheumatology Physician is a mid-sized specialty nationwide, with 6,181 enrolled providers across 52 states and an average of 2,054 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.
