DANIEL HERZIG, MD appears in the CMS NPPES registry as a Colon & Rectal Surgery Physician provider holding MD credentials at 3303 SW BOND AVE, PORTLAND, OR, 97239, with a listed phone of (503) 494-4373. NPI 1841205358 was issued on 07/31/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HERZIG 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 283 prescription claims written by this provider, covering 167 Medicare beneficiaries and totaling roughly $10K in drug spend, split 28% brand-name and 72% generic by claim count, with an opioid prescribing rate of 4.9%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 100/100 for the 2023 performance year, compared with the national average of 83.1.

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.
