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).

LOUIS CRISTOL, M.D. is a Nuclear Cardiology Physician provider practicing in BURLESON, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1699750471. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

LOUIS CRISTOL, M.D. appears in the CMS NPPES registry as a Nuclear Cardiology Physician provider holding M.D. credentials at 209 OLD HIGHWAY 1187, BURLESON, TX, 76028, with a listed phone of (822) 686-7006. NPI 1699750471 was issued on 12/14/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CRISTOL 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 3,634 prescription claims written by this provider, covering 498 Medicare beneficiaries and totaling roughly $643K in drug spend. 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.

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.
