WILLIAM SUGARMANN, M.D. appears in the CMS NPPES registry as a Single Specialty Group provider holding M.D. credentials at 30 REHILL AVE, SOMERVILLE, NJ, 08876, with a listed phone of (908) 927-8994. NPI 1982717880 was issued on 08/16/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SUGARMANN 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 65 prescription claims written by this provider, covering 60 Medicare beneficiaries and totaling roughly $263 in drug spend, with an opioid prescribing rate of 60.0%. 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.

Single Specialty Group is a narrow specialty nationwide, with 24 enrolled providers across 16 states and an average of 7,180 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.
