Terence Mayers, MD appears in the CMS NPPES registry as a Surgery Physician provider holding MD credentials at 441 N LAKEVIEW AVE, Anaheim, CA, 92807, with a listed phone of (888) 988-2800. NPI 1669520649 was issued on 01/08/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Mayers 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 101 prescription claims written by this provider, covering 48 Medicare beneficiaries and totaling roughly $6K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 18.8%. 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.

Surgery Physician is a mid-sized specialty nationwide, with 36,191 enrolled providers across 56 states and an average of 169 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.
