MARK BRIGGS, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 867 S VANGUARD WAY, MERIDIAN, ID, 83642, with a listed phone of (208) 463-3000. NPI 1861726259 was issued on 10/01/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRIGGS 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 550 prescription claims written by this provider, covering 114 Medicare beneficiaries and totaling roughly $21K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 3.1%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 83.3209/100 for the 2023 performance year (Quality 79.5148, Cost 64.8883), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 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.
