How to Join Aetna’s Network: Contracting & Credentialing (Step-by-Step

Step 1: Request to Participate

1. Identify your provider category. Are you an individual physician/provider, a group practice, a facility, or an ancillary provider?
2. Submit the “Request to Join” (sometimes called “Request to Participate”) form on Aetna’s website.
3. Panel review. Aetna reviews whether there is a panel opening in your geographic area and lets you know if the application will move forward.
   • If accepted: A network manager will contact you to begin contracting.
   • If denied: You’ll receive notice that no contract will be pursued at this time.

Step 2: Contracting

Once your request to participate is accepted:

• A network representative sends you a contract (often via an e-signature platform such as Adobe Sign) to review and sign.
• The agreement includes terms & conditions, reimbursement rates, credentialing requirements, and provider responsibilities—review carefully.
• Contracts may auto-renew; changes to rates or services often require renegotiation.

Step 3: Credentialing

Credentialing is separate from contracting. You must be credentialed and under contract to begin seeing Aetna patients.

What Credentialing Involves

• Collecting and verifying professional qualifications: licensure, certifications, liability insurance, board certification (where applicable), training/residency, hospital privileges, DEA registration (if applicable), etc.
• Using CAQH ProView in many states, authorize Aetna to access your CAQH data.
• Primary source verification with state licensing boards, NPDB, and other sources as required.

Estimated Timeline

• Credentialing may take 60–90 days (or more) after the contract is signed and a complete (“clean”) credentialing packet is received.
• Aetna provides acknowledgment of receipt and will inform you if information is incomplete.

Step 4: Finalization & Welcome

• After credentialing approval, Aetna countersigns the contract and issues your effective participation date. This is when you can start submitting claims and seeing patients under Aetna’s network.
• You’ll receive welcome materials, a provider identification number (PIN) or similar details, and your practice will appear in Aetna’s provider directory.

Contacting Aetna: Key Phone Numbers & Resources

• Credentialing status (medical/behavioral health): 1-800-353-1232 (TTY 711)
• Dental network questions: 1-800-451-7715 (TTY)
• Medicare Advantage provider questions: 1-800-624-0756 (TTY)
• Other questions/network participation: 1-888-632-3862 (TTY)
• CAQH ProView Help Desk: 1-888-599-1771

Tips & Best Practices

• Keep your CAQH profile complete and current, and designate Aetna as an authorized plan. Missing or outdated data causes delays.
• Review the contract thoroughly—especially the fee schedule and reimbursement terms. Clarify anything unclear before signing.
• Monitor credentialing status. If the process seems delayed, call the credentialing number above.
• For groups, ensure each provider submits any required individual application in addition to the group information.
• Maintain organized records: letters of approval, effective dates, signed contracts, and credentialing confirmations.
• Understand the distinction: Contracted ≠ Credentialed. You must complete both to officially participate.

Common Pitfalls & What to Watch

• Incomplete applications or documentation. Missing items can delay or derail credentialing.
• Signing without a fee schedule review. Be sure you understand reimbursement rates and any related terms.
• Incorrect identifiers for groups vs. individuals. Double-check the appropriate NPI/EIN combinations for your structure.
• Assuming credentialing alone equals participation. You’re not active until the contract is fully executed and an effective date is issued.

Conclusion

Joining Aetna’s network is a multi-step process dependent on both contract execution and credentialing approval. By preparing documentation in advance, staying responsive, tracking timelines, and understanding each stage, you can help your practice navigate the process smoothly and start seeing Aetna-insured patients with confidence.
