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).

Christine Contreras, M.D. appears in the CMS NPPES registry as a General Practice Physician provider holding M.D. credentials at 14345 BLANCO RD, San Antonio, TX, 78216, with a listed phone of (210) 802-7003. NPI 1619133238 was issued on 08/04/2008.

Medicare Part D records for calendar year 2023 show 495 prescription claims written by this provider, covering 77 Medicare beneficiaries and totaling roughly $156K in drug spend, split 19% brand-name and 78% generic by claim count.

On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 0/100 for the 2023 performance year (Quality 0), compared with the national average of 83.1.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 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.

  • Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Texas medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby General Practice Physician peer on Medicare volume and prescribing patterns. Compare providers
