ZACHARY SHIELDS, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 1000 HEALTH CENTER DR, MATTOON, IL, 61938, with a listed phone of (217) 238-4960. NPI 1760137921 was issued on 02/16/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SHIELDS 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 242 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $22K in drug spend, split 7% brand-name and 93% generic by claim count. 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 91.8056/100 for the 2023 performance year (Quality 75.5932), 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.
