Oklahoma Healthcare Provider Overview

Healthcare in Oklahoma is served by a network of providers across major cities including Oklahoma City, Tulsa, Norman, Broken Arrow, Edmond. Oklahoma providers span all medical specialties — from primary care physicians and family medicine to specialized surgical centers, behavioral health providers, and long-term care facilities. All providers who accept insurance, bill Medicare or Medicaid, or participate in electronic health record systems are listed in the NPPES NPI registry with active NPI records.

Oklahoma Medical Board

The Oklahoma State Board of Medical Licensure and Supervision is the state regulatory authority that issues and oversees medical licenses in Oklahoma. For license status verification, disciplinary actions, and medical board certification, visit the official website at https://www.okmedicalboard.org. While this NPI lookup tool confirms a provider's federal NPPES enrollment, state license verification through the Oklahoma State Board of Medical Licensure and Supervision is a separate but equally important step in complete provider credential verification. Both NPPES and state board data should be checked during credentialing workflows.

The most commonly registered specialties in the NPPES registry for Oklahoma include internal medicine, family medicine, general surgery, pediatrics, obstetrics and gynecology, cardiology, orthopedics, psychiatry, neurology, and radiology.
