How to Get Credentialed With Blue Cross Blue Shield

Mukesh MakwanaFounder & CEO · Hands-on medical billing & RCM across 11 specialties · Reviewed October 1, 2026

There is no single "Blue Cross Blue Shield" to apply to. The Blue Cross Blue Shield Association describes itself as an association of independent, locally operated Blue Cross and Blue Shield companies, so you get credentialed with the Blue company that covers the state where you practice. That one company then becomes your contact for its own members, for out-of-state Blue members through the BlueCard program, and for federal employees in the Federal Employee Program. This page explains how that works and the steps that apply at almost every Blue plan.

Step 1: find your local Blue plan

Each state, and in some states each region, has its own Blue company with its own provider network, contracts and credentialing team. Some operate under the Blue Cross Blue Shield name with the state attached; others use their own brand, such as Anthem, Highmark, Florida Blue or Regence. Start on your local plan's provider website, usually under a heading like "Join our network" or "Network participation". Everything that follows, from the application to the contract and the effective date, runs through that plan.

Step 2: get your CAQH profile ready

Most Blue plans credential through CAQH ProView. As one example, Blue Cross and Blue Shield of Texas requires physicians and other professional providers to use CAQH for initial credentialing and recredentialing, and says that if the CAQH application is not finalized within 45 days, the credentialing process is discontinued and has to start over. Before you apply anywhere:

• Complete and attest your CAQH profile, and keep re-attesting every 120 days (every 180 days in Illinois), per the CAQH quick reference guide.
• Authorize the Blue plan to view it, either globally or by naming the plan.
• Make the practice name, address, tax ID and NPI identical in CAQH, NPPES and the application.

Our CAQH ProView help page walks through each step.

Step 3: request to join and complete the application

Most Blue plans start with a participation request or network application, then credential the provider before or alongside the contract. The details differ by plan, which is why the plan's own pages matter. Blue Cross and Blue Shield of Texas, for example, publishes:

• A Texas initial credentialing checklist to review before applying, and a list of provider types that require full credentialing.
• An expedited "provisional network participation" status for applicants who have a valid BCBSTX provider record ID, a signed contract, a complete CAQH application authorized to BCBSTX, and a Texas license in good standing.
• That it reviews CAQH applications for completeness in an average of 8 to 10 calendar days, and assigns each provider a network effective date that may differ from the contract effective date.
• That applicants in a training program are not eligible for network participation.

Your plan's rules will look similar but not identical. Read its checklist before you submit, not after a request for missing items.

Step 4: the contract and the effective date

Credentialing approves you; the contract and the effective date put you in network. Do not bill Blue members as in network until you have both in writing. If you work in a group, confirm that each clinician is linked to the group's contract and tax ID, not only credentialed as an individual.

How long BCBS credentialing takes

Blue plans set their own timelines, and most do not publish one total figure, because the time depends on how complete the application is, whether the network is open for your specialty and area, and contracting. What you control is the part before the plan: a complete, attested and authorized CAQH profile, matching details everywhere, and a prompt answer to every request. Blue Cross and Blue Shield of Texas itself describes credentialing as a very involved process and asks providers to allow enough time before checking status. Our guide to how long insurance credentialing takes covers what is published for other payers.

How to check your BCBS credentialing status

Each Blue plan has its own status channel. Blue Cross and Blue Shield of Texas, for example, provides case and credentialing status checkers on its provider site and directs other requests to the provider's network management consultant. Keep your application date, CAQH ID, NPI and tax ID ready, and note every contact.

Seeing patients from other Blue plans: BlueCard

Once you are in your local Blue plan's network, you can usually see members of other Blue plans through the BlueCard program. BlueCross BlueShield of South Carolina's BlueCard claims page explains the practical points:

• BlueCard members have a three-character prefix at the start of their ID number, and the prefix is key to prompt payment, so always use the full, accurate member ID.
• Benefits and eligibility for out-of-area members can be checked by calling 800-676-BLUE (2583) with the prefix.
• Prior authorization rules come from the member's home plan, which you can check with the BlueCard precertification tool.
• Claims are submitted to your local plan, preferably electronically.

Federal employees: the Federal Employee Program

The Blue Cross and Blue Shield Federal Employee Program covers federal employees and their families. Its provider resources page sends providers to their local Blue company for questions about the contract, the provider directory listing, prior approvals, claims and member eligibility. In practice, the route into FEP for a provider is the local Blue plan's network.

Therapists and behavioral health practices

For therapists, the steps are the same, with two additions. First, some Blue plans manage behavioral health through a separate vendor or department, so check whether the plan's behavioral health network has its own application. Second, associate-level clinicians are often not credentialed on their own; check the plan's written policy before scheduling. See credentialing services for therapists and the payer guides for Aetna, Cigna and Evernorth and Optum.
