JEFFREY BARTON, M.D. appears in the CMS NPPES registry as a Colon & Rectal Surgery Physician provider holding M.D. credentials at 9900 SE SUNNYSIDE RD, CLACKAMAS, OR, 97015, with a listed phone of (800) 813-2000. NPI 1295988350 was issued on 11/02/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BARTON 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 190 prescription claims written by this provider, covering 84 Medicare beneficiaries and totaling roughly $3K in drug spend, split 7% brand-name and 93% generic by claim count, with an opioid prescribing rate of 21.1%. 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.

Colon & Rectal Surgery Physician is a narrow specialty nationwide, with 1,608 enrolled providers across 50 states and an average of 196 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.
