The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

BRUCE GILLILAND, O.D. appears in the CMS NPPES registry as a Low Vision Rehabilitation Optometrist provider holding O.D. credentials at 715 CALLAHAN DR, KNOXVILLE, TN, 37912, with a listed phone of (865) 687-1232. NPI 1184622441 was issued on 07/11/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GILLILAND 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 238 prescription claims written by this provider, covering 61 Medicare beneficiaries and totaling roughly $25K in drug spend, split 26% brand-name and 74% 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.

Low Vision Rehabilitation Optometrist is a narrow specialty nationwide, with 299 enrolled providers across 39 states and an average of 296 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.
