The complete credentialing guide for healthcare providers in the United States. Learn what credentialing is, the differences between Medicare, Medicaid, and commercial insurance credentialing, CAQH's role, credentialing timelines, and re-credentialing requirements.

What is Healthcare Credentialing?

Healthcare credentialing is the systematic process of verifying that a healthcare provider is qualified, licensed, and eligible to treat patients and receive insurance payments. This verification process ensures that providers meet the standards set by insurance companies, regulatory bodies, and healthcare organizations before they can participate in insurance networks.

Credentialing involves verifying a provider's education, training, licenses, certifications, work history, and professional background. Without proper credentialing, healthcare providers cannot bill insurance companies or receive reimbursement for services provided to insured patients.

Why Credentialing Matters

  • Required for insurance payments - Without credentialing, providers cannot bill insurance companies
  • Patient safety - Ensures providers are qualified and competent
  • Regulatory compliance - Meets federal and state requirements
  • Network participation - Required to join insurance networks

What Gets Verified

  • Medical license - State licensure verification
  • Education & training - Medical school, residency, fellowships
  • Certifications - Board certifications and specialty credentials
  • Work history - Previous employment and practice locations
  • Malpractice insurance - Coverage and claims history
