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).

OSCAR MARTINEZ, M.D. is a Obstetrics Physician provider practicing in TAHOKA, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1326364381. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

OSCAR MARTINEZ, M.D. appears in the CMS NPPES registry as a Obstetrics Physician provider holding M.D. credentials at 2600 LOCKWOOD ST, TAHOKA, TX, 79373, with a listed phone of (806) 998-4533. NPI 1326364381 was issued on 04/15/2010.

Medicare Part D records for calendar year 2023 show 1,650 prescription claims written by this provider, covering 248 Medicare beneficiaries and totaling roughly $380K in drug spend, split 22% brand-name and 78% generic by claim count, with an opioid prescribing rate of 0.8%.

Obstetrics Physician is a narrow specialty nationwide, with 1,402 enrolled providers across 54 states and an average of 319 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.
