To credential with Aetna as a behavioral health provider, start by submitting Aetna's online request to join its network. If Aetna determines that it needs providers in your service area, it will guide you through contracting and credentialing. You must also complete your CAQH profile, authorize Aetna to access it, and provide any additional information requested during review.

The process is not complete just because your CAQH profile is active. You need to confirm that Aetna has approved your participation, finalized the applicable contract, and activated your provider record before billing as an in-network clinician.

This guide explains how individual therapists, psychologists, psychiatrists, and group practices can approach Aetna credentialing, which documents to prepare, whom to contact, and what to check before submitting claims.

Aetna Credentialing at a Glance

Aetna's process can vary by provider type, location, and network need. Its official Join the Aetna Network page and network FAQs should be your starting points.

Step 1: Check Whether Aetna Is Accepting Providers in Your Area

Aetna does not automatically contract with every clinician who submits a request. It reviews requests against its network needs in a particular geographic area and determines whether contracting or credentialing is required.

Start with Aetna's online network application. Select the option for behavioral health rather than the medical, dental, pharmacy, or facility pathway.

Before applying, clarify:

• Your provider type: For example, licensed clinical social worker, psychologist, psychiatrist, professional counselor, or another eligible behavioral health professional.
• Your service location: Network availability can differ by state and local market.
• Your practice structure: Determine whether you are applying as an individual clinician, joining an existing group, or establishing a group practice.
• Your intended products: Identify the Aetna commercial or other applicable networks you want to participate in. Do not assume every Aetna-branded plan uses identical participation or billing rules.

If you are joining a group that already contracts with Aetna, contact the group's credentialing or provider-enrollment team before submitting a separate request. The correct process may depend on the group's existing arrangement and your role.

Important: Aetna's participation request, credentialing review, and contracting are related but separate steps. Submitting an application does not guarantee that Aetna will offer a contract.

Step 2: Prepare Your Documents Before Applying

Gather your information before starting the application. Incomplete or inconsistent records can lead to follow-up requests and delays.

Aetna credentialing checklist

Use this list to prepare for your application and CAQH review.

• Individual National Provider Identifier (NPI), generally Type 1
• Group or organization NPI, if applicable
• Current professional license for each relevant state
• Education, training, and professional qualifications
• Board certification, if applicable
• Work history and explanations for any gaps requested by the application
• Malpractice or professional liability insurance certificate
• Practice address, phone number, and service-location details
• Tax identification information and W-9, as requested
• Current professional contact information
• CAQH Provider Data Portal profile and supporting documents
• Any additional disclosures or documents requested by Aetna

The exact requirements depend on the clinician, provider type, state, and application. Use Aetna's instructions and the applicable CAQH requirements rather than treating this checklist as a substitute for the official application.

For a group practice, prepare information at both the individual and organizational levels. A group's tax ID and NPI do not replace the individual clinician's qualifications or credentialing requirements.

Step 3: Complete Your CAQH Profile

Aetna's provider-network FAQs identify CAQH as a source it uses for credentialing and recredentialing. Two naming notes: ProView is the retired name and proview.caqh.org no longer resolves, so sign in at portal.caqh.org; and CAQH itself has rebranded to DataSpring, though the portal still carries the CAQH name.

If you already have a CAQH profile, do not automatically create a second one. Review the existing profile and confirm that your information is accurate and current.

Check the following:

• Personal and professional information
• State licenses and expiration dates
• Education, training, and work history
• Practice locations and contact details
• Malpractice coverage
• Required supporting documents
• Attestation status

Then authorize Aetna to access your CAQH information. An active CAQH profile does not necessarily mean Aetna can retrieve it. If Aetna is not authorized, the credentialing process may stall even when the information is otherwise complete.

Sign in at portal.caqh.org. For a fuller walkthrough of the platform, see our CAQH credentialing guide, and the attestation guide for the Review and Attest step.

Step 4: Submit Aetna's Request to Join the Network

Complete the behavioral health request through Aetna's Join the Network page.

Enter the requested details carefully, including your professional information and primary service location. Keep a copy of your submission and any confirmation number or email.

After you submit the request, Aetna reviews whether it needs additional providers in your area. If it decides to proceed, it will provide instructions for the next stages.

Aetna's published workflow says it will evaluate network needs and, if applicable, begin contracting before obtaining the credentialing application from CAQH. Make sure Aetna is authorized to access your profile so it can retrieve the necessary information.

If you are already registered with CAQH, you generally do not need to create a new profile simply because you are applying to Aetna. Confirm that your profile is complete and that Aetna has permission to view it.

Step 5: Complete Credentialing and Contracting

Credentialing verifies a provider's professional qualifications. Aetna describes this review as including relevant training, licenses, certification or registration, academic background, and other information used to assess professional competence and conduct.

Contracting is separate. It establishes the terms under which you participate in the network.

Depending on your application, you may need to respond to requests for clarification, correct discrepancies, provide updated documents, or review and execute a contract.

Keep an eye on the email address you supplied for credentialing. Aetna specifically advises providers to maintain an up-to-date, credentialing-specific email address because missed requests for information can slow the process.

Before signing a contract, review:

• The legal entity and tax ID associated with the agreement
• The clinician or clinicians covered by the arrangement
• The participating products and networks
• The fee schedule and reimbursement terms
• Claims-submission and timely-filing provisions
• Requirements for recredentialing and provider-data updates
• Contract effective-date and termination provisions

If you have questions about a contract or the networks included, ask Aetna for clarification before assuming that one agreement covers every product you want to accept.

How long does Aetna credentialing take?

There is no single timeline that applies to every Aetna behavioral health application. Timing depends on network need, provider type, the completeness of your application, the credentialing review, contracting, and any additional information requests.

Aetna's network page describes a process in which it first reviews the participation request, then proceeds with contracting and credentialing where applicable. Its current process takes precedence over any generic industry estimate. For planning purposes rather than prediction, our guide to credentialing timelines sets out the usual stages and where they stall.

To avoid unnecessary delays:

1. Submit a complete and accurate request.
2. Authorize Aetna to access CAQH.
3. Keep your supporting documents current.
4. Monitor the email account used for credentialing.
5. Respond promptly to requests for clarification.
6. Follow up through Aetna's official contact channels if the application appears stalled.

Do not start treating Aetna members at an assumed in-network rate simply because you submitted an application or received a preliminary response.

Step 6: Confirm Your Effective Date Before Billing

Approval, contracting, and activation are not interchangeable. Before submitting claims as an in-network provider, confirm the effective date and verify that Aetna's systems reflect the correct provider and practice information.

Ask Aetna to clarify:

• Whether credentialing is complete
• Whether the contract has been finalized
• Your in-network effective date
• Which products or networks you are approved to participate in
• The provider identifier or other enrollment information needed for billing
• Whether your individual NPI, group affiliation, tax ID, and service location are correctly linked

The date you submitted your request is not necessarily your effective date. Do not assume that claims for earlier services will automatically be reimbursed at contracted rates. If you need to bill for services delivered during the application period, ask Aetna how the applicable contract and state requirements treat those claims.

Once activated, verify your listing in the relevant provider directory and make sure the details patients use to find you are correct.

Aetna Credentialing Phone Number and Provider Contacts

If you need help with Aetna provider credentialing, use the contact information Aetna publishes for network participation and provider support.

All four numbers were checked against Aetna's own contact and Availity pages. Two are easy to transpose: Aetna also publishes 1-800-872-3862, which is a different line, so check the digits before dialling.

Sources: Aetna: contact us · Aetna: Availity provider portal

These numbers serve different purposes. For a new behavioral health provider asking about network participation or credentialing, start with Aetna's network and credentialing support line. For an existing provider asking about a claim or contracted plan, use the applicable provider-services contact.

For certain Aetna Signature Administrators, Meritain Health, mental health services, or substance use treatment arrangements, Aetna directs providers to the number on the member ID card. Confirm the administrator and product before using a general Aetna number.

Phone numbers and routing instructions can change, so verify them on Aetna's official contact page before calling.

Step 7: Set Up Availity for Day-to-Day Provider Transactions

Credentialing gets you through the network-entry process. Once you are participating, you also need an operational workflow for eligibility checks, claims, authorizations, and payment follow-up.

Aetna uses its provider portal on Availity for many provider transactions. Aetna lists functions that include:

• Submitting claims and encounters
• Checking patient eligibility and benefits
• Reviewing claim status
• Requesting or checking precertification and referrals
• Uploading supporting documentation
• Reviewing electronic remittance advice
• Filing disputes and appeals
• Updating provider information where supported

Start at Aetna's Availity provider portal page. If your practice already has an Availity account, contact the office administrator to arrange access. If your practice is new to the portal, follow Aetna's registration instructions.

Do not confuse Availity registration with credentialing approval. Availity is an operational portal for working with Aetna; it does not replace Aetna's network participation, contracting, or credentialing decisions.

What is Aetna's payer ID?

There is not one payer ID that should be assumed to work for every Aetna-branded product and claims arrangement. The correct electronic payer destination can depend on the member's plan, administrator, and transaction setup.

Before submitting claims:

1. Check the member's ID card and plan details.
2. Confirm the applicable payer destination in your clearinghouse or Availity workflow.
3. Verify that the claim is being submitted under the correct billing entity and provider identifiers.
4. Check the electronic acknowledgment or rejection report.
5. Resolve routing errors before resubmitting.

Do not select a payer ID based only on the word Aetna appearing in a payer list. For members whose coverage is administered by another organization, the correct claims destination may be different. When uncertain, confirm the instructions with the plan or the number on the member's ID card.

Step 8: Understand Timely Filing Before Your First Claim

Timely filing is the deadline for submitting a claim after a service is provided. Miss it and the claim is denied even when the service was covered, and a late-filing denial is one of the harder ones to overturn.

Do not assume that one timely-filing limit applies to every Aetna plan. The deadline can depend on the contract, product, state requirements, and other applicable terms. Aetna's published state-specific provider materials include filing provisions that may not apply universally to every provider.

Before your first claim, confirm:

• The timely-filing deadline in your executed contract and applicable provider manual
• Whether the rule differs for initial claims, corrected claims, or reconsiderations
• Whether electronic submission is required or preferred
• How the plan handles claims rejected for missing or invalid information
• Which process applies if a claim is denied as untimely

Build a submission process that allows time to correct rejections before the filing deadline. Track the date of service, submission date, clearinghouse acceptance, payer receipt, and claim status. A clearinghouse rejection is not the same as confirmation that Aetna has accepted and adjudicated the claim.

For Aetna's electronic transaction options, consult its official provider transaction resources and the applicable provider manual.

Common Aetna Credentialing Mistakes

1. Assuming CAQH registration completes the process

CAQH is a data source Aetna uses for credentialing. You still need to request network participation, authorize Aetna to access your information, and complete any required contracting and credentialing steps.

2. Applying through the wrong pathway

A behavioral health clinician, medical provider, dental provider, and facility may have different application routes. Start with the category that matches your provider type.

3. Leaving CAQH incomplete or outdated

Expired licenses, old practice addresses, missing documents, or an outdated attestation can create avoidable follow-up work. Review your profile before submitting your request and keep it current during the review.

4. Missing an information request

Aetna has highlighted the importance of keeping a current credentialing-specific email address so its team can reach providers when additional information is needed. Monitor your inbox and spam folder during the application.

5. Assuming approval means every Aetna plan is included

Confirm the products and networks covered by your agreement. Do not infer participation in every Aetna-branded or third-party-administered plan from one approval.

6. Billing before verifying the effective date

A submitted application or verbal update is not a substitute for confirmation of your participation status and effective date. Verify the details before treating a claim as in-network.

7. Treating the payer ID and timely-filing deadline as universal

Verify the claim destination and filing requirements for the member's actual plan and your contract. Incorrect routing and missed deadlines can create avoidable denials and rework.

Should You Manage Aetna Credentialing In-House or Use a Credentialing Service?

A solo clinician with one application and a well-maintained CAQH profile may be comfortable managing credentialing independently. A growing group practice, however, may have to coordinate multiple clinicians, practice locations, tax IDs, contracts, and recredentialing dates across several payers.

A credentialing service may be useful if your team needs help with:

• Preparing and checking applications
• Maintaining CAQH profiles and supporting documents
• Following up on pending applications
• Tracking effective dates and payer status
• Coordinating enrollment information across clinicians and locations
• Managing recurring recredentialing and provider-data updates

Before hiring a service, clarify exactly what it handles. Ask whether it submits applications, follows up with Aetna, monitors requests for information, verifies effective dates, and supports ongoing recredentialing. Also establish who is responsible for keeping source documents and provider information accurate.

Our insurance credentialing guide explains the broader payer-enrollment process for private practices, and credentialing vs contracting vs enrollment covers why an Aetna approval is not the same as an Aetna contract. If your team wants credentialing and re-attestation managed as ongoing operational work, Supabill is one option to evaluate.

Frequently Asked Questions About Aetna Credentialing

How do I apply for Aetna credentialing as a therapist?

Start with Aetna's Join the Network page and select the behavioral health application. Aetna reviews network need in your area and determines whether contracting and credentialing are required. Complete your CAQH profile and authorize Aetna to access it.

What is the Aetna credentialing phone number?

Aetna publishes 1-800-353-1232 as its network and credentialing support line. For questions about existing non-Medicare plans, including individual and family plans, it lists 1-888-632-3862. Check Aetna's contact page for current routing, since numbers and queues change.

Does Aetna use CAQH for behavioral health credentialing?

Yes. Aetna's provider-network FAQs state that it uses CAQH for credentialing and recredentialing. Providers should ensure their profile is complete and authorize Aetna to access it. CAQH registration alone does not establish in-network participation.

How long does Aetna credentialing take?

There is no single timeline for all applications. The process depends on network need, the completeness of the application, credentialing review, contracting, and any additional information requests. Ask Aetna about the status of your specific application rather than relying on a generic industry estimate.

Can I see Aetna patients while credentialing is pending?

You may be able to see a patient under an arrangement that is permitted by the applicable plan and contract, but you should not assume you can bill at the in-network rate before your effective date. Confirm participation status, effective-date rules, and any applicable state requirements directly with Aetna.

Does Aetna require Availity?

Aetna uses Availity for many routine provider transactions, including eligibility, claims, authorizations, and claim-status inquiries. Availity supports day-to-day administration, but it does not replace the credentialing and contracting process.

What is Aetna's payer ID for behavioral health claims?

Do not assume that one payer ID applies to every Aetna product. Verify the correct destination using the member's plan details, your clearinghouse or Availity setup, and Aetna's instructions. For third-party-administered coverage, use the plan-specific claims information.

Does Aetna credential behavioral health providers through CAQH?

Yes. Aetna's provider-network FAQs identify CAQH as a source it uses for credentialing and recredentialing. Note that CAQH has rebranded to DataSpring and the sign-in address is portal.caqh.org; proview.caqh.org no longer resolves.

Is there a separate Aetna number for behavioral health credentialing?

Not a distinct one. Aetna publishes 1-800-353-1232 as its network and credentialing support line across provider types. For existing non-Medicare plans, including individual and family plans, it lists 1-888-632-3862.

What is Aetna's timely-filing limit?

The applicable limit depends on the plan, contract, state requirements, and claim circumstances. Check your executed agreement and the provider manual applicable to the member's plan. Do not use a deadline from an unrelated Aetna product as a universal rule.

Final Takeaway

Aetna credentialing involves more than filling out an application or maintaining a CAQH profile. Start with the correct behavioral health participation request, make sure Aetna can access your CAQH information, complete the credentialing and contracting steps, and verify your effective date before billing as an in-network provider.

After activation, prepare your operational workflow as carefully as your application. Confirm plan participation, payer routing, timely-filing requirements, and Availity access so your practice can manage eligibility checks, claims, and payment follow-up with fewer avoidable errors.
