How MIPS and board certification work
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).
Ahmad Ata, MD appears in the CMS NPPES registry as a Legal Medicine provider holding MD credentials at 5550 WARREN PKWY STE 100, Frisco, TX, 75034, with a listed phone of (214) 618-0808. NPI 1972525939 was issued on 07/25/2006.
Medicare Part D records for calendar year 2023 show 3,117 prescription claims written by this provider, covering 330 Medicare beneficiaries and totaling roughly $786K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 1.1%. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 75/100 for the 2023 performance year, compared with the national average of 83.1.
Legal Medicine is a narrow specialty nationwide, with 1,065 enrolled providers across 51 states and an average of 2,821 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.
