What Is Physician Credentialing?

Physician credentialing is the structured process of verifying a medical provider’s qualifications, licensure, training, professional experience, and clinical competencies to ensure they meet the standards required by health plans and regulatory bodies.

Credentialing includes:

• Verifying medical education, residency, and board certification
• Checking for disciplinary actions or malpractice claims
• Ensuring compliance with state licensure laws
• Approving providers for insurance network participation

Importance of Credentialing for Internal Medicine Physicians

Patient Access and Referrals

Without credentialing, internal medicine physicians cannot accept insured patients or participate in primary care networks, which drastically limits patient volume.

Revenue Cycle Management

Credentialing is directly linked to billing and reimbursements. Claims from uncredentialed providers are denied or delayed, leading to cash flow disruptions.

Legal Compliance

California has strict regulations enforced by the Medical Board of California and the Department of Managed Health Care (DMHC). Credentialing ensures compliance.

Institutional Affiliation

Hospitals and healthcare networks require credentialed providers to grant admitting privileges and inclusion in collaborative care programs.

Regulatory Landscape in California

Oversight Bodies

• Medical Board of California – Manages licensing and investigations
• DMHC – Oversees managed care organizations
• Department of Health Care Services (DHCS) – Administers Medi-Cal
• Centers for Medicare and Medicaid Services (CMS) – Governs federal programs like Medicare

State-Specific Requirements

• Timely recredentialing (typically every 2-3 years)
• Hospital privileges may be required for certain networks
• Participation in Medi-Cal managed care may require additional credentialing

Step-by-Step Credentialing Process for Internal Medicine Physicians

Step 1: Prepare Your Credentials

Gather all necessary documents:

• Medical school diploma
• Residency and internship records
• Board certification (ABIM)
• California medical license
• DEA registration
• NPI number
• Malpractice insurance policy and claims history
• Hospital affiliation letters

Step 2: Create and Maintain a CAQH Profile

CAQH ProView is required by most California payers:

• Enter all professional details
• Upload credentialing documents

• Blue Shield of California

Step 4: Credentialing Verification Process

Insurance companies and hospitals conduct Primary Source Verification (PSV) to confirm:

• License and DEA status
• Malpractice claims
• Work history

Step 5: Contracting and Enrollment

Step 6: Recredentialing

Most insurers require recredentialing every 2–3 years. Missed recredentialing deadlines can cause deactivation.
