      Navigating Insurance Networks: A Provider’s Guide to Credentialing, Contracting, Enrollment, and Out-of-Network Registration

      This guide breaks down everything you need to know to successfully navigate insurance networks, from credentialing and contracting to enrollment and out-of-network registration—making the process clear and easy for new providers!

      Credentialing: What It Is and Why It Matters

      What is Credentialing?
      Credentialing is the process of verifying your qualifications as a healthcare provider. This includes checking:

      • Your education and training

      • Your license

      • Any board certifications

      • Your work history

      • Your malpractice history and insurance

      • References

      Why is Credentialing Important?
      Credentialing ensures you are qualified to provide safe and quality care to patients.

      Who Does Credentialing?

      • Insurance companies (payors)

      • Hospitals

      • Credentialing verification organizations (CVOs)

      When Does Credentialing Happen?
      You will need to be credentialed before you can work at a facility or join an insurance network.

      Contracting: Becoming Part of an Insurance Network

      What is Contracting?
      Contracting is when you agree to the terms set by an insurance company, including:

      • Reimbursement rates (how much you’ll be paid for services)

      • Covered services (which services the insurance covers)

      • Terms of being in-network (your rights and responsibilities as a network provider)

      Why is Contracting Important?
      Contracting ensures you are officially part of the insurance company's network, which allows you to see their patients and get paid according to agreed rates.

      Who Does Contracting?

      • The insurance company

      • You or your representative (like a billing or credentialing specialist)

      When Does Contracting Happen?
      Contracting usually happens after your credentialing is approved.

      Out-of-Network (OON) Registration: What If You’re Not in the Network?

      What is Out-of-Network Registration?
      When you register as an out-of-network provider, you are not part of the insurance company’s network. However, you can still submit claims for patients covered by that insurer.

      Why is OON Registration Important?
      It allows you to:

      • Bill the insurance company

      • Meet specific payer requirements (like submitting your NPI, license, and W-9)

      What’s Involved in OON Registration?

      • Filling out a simple registration form

      • Submitting your W-9, license, Demographics, and NPI

      • No negotiation of rates or credentialing needed

      • Payments may go to the patient, not always to you

      • Some insurance companies (United Healthcare for example) require you to submit a claim to finalize your registration. 

      Enrollment: Getting Recognized by the Insurance Company

      What is Enrollment?
      Enrollment is the process of submitting your information to the insurance company so they can add you to their system. (Ex: Medicare enrollment)

      Why is Enrollment Important?
      Enrollment ensures that your claims are processed and paid correctly, and that you are officially recognized by the insurance company.

      What’s Involved in Enrollment?

      • Completing and submitting the enrollment forms (which are often different from the credentialing forms)

      • Providing supporting documents (e.g., license, W-9, NPI)

      • Receiving confirmation of enrollment, including your provider ID and effective date

      Who Does Enrollment?

      • The insurance company’s provider relations department

      • You or your representative (billing or credentialing specialist)

      When Does Enrollment Happen?

      • After your credentialing and contracting are done (for in-network providers)

      • Can happen as part of OON registration (depending on the insurer)

      Note: You may come across the term "enroll in a clearinghouse." This simply means you need to register as a provider with the clearinghouse in order to submit claims electronically.
