Some insurers require your practice and clinician information to be registered before they can process out-of-network claims. Registration establishes your provider record; it does not mean joining the insurer’s network.
This page covers BCBS umbrella-plan registration and TRICARE East and West provider certification. These are separate payer processes. For BCBS, choose the guide for your practice or claim-service location. For TRICARE, choose the correct region and provider type.
For BCBS, the practice completes registration, not the client. Looking for a plan’s billing or reimbursement options? See the Insurance plan table. Provider registration and certification are separate requirements; a listing does not establish that they are complete.

​
What you can share with your client

Our practice handles any provider registration the insurer requires. Checking your benefits is a separate step and does not confirm that registration is complete. Your insurer decides the claim outcome. You can also contact Support through your own payment portal account about your account or claim.

​
Choose your next step for BCBS

  • New registration or unsure whether a record exists: Check with the payer for an existing practice record under your tax ID and service location, then complete the applicable payer process.
  • Adding a clinician to an existing practice: Use the payer’s addition or update process. Confirm any required individual enrollment and affiliation with your practice; do not create a new practice just to add a clinician.
  • Application submitted: Check your pending registration. Do not restart or submit a duplicate application unless the payer asks you to.
  • Practice and required clinician affiliations confirmed active: Notify Thrizer after BCBS approval.

Complete the payer process

Have your practice’s EIN/TIN, each clinician’s individual rendering NPI, and the practice or claim-service address ready. Many plans also ask for each clinician’s professional license type and number, the issuing state, and the license’s issue and expiration dates. Make the practice and clinician details submitted to each required plan match the information in Thrizer exactly. Follow your payer’s out-of-network or non-participating instructions, including any required clinician enrollment and group affiliations. Solo practitioners register the practice using their own NPI.

​
BCBS registration

For BCBS umbrella claims through Thrizer, register with each required Local / Host Blue Plan for the practice or service location used for billing. This may differ from the client’s plan shown on their insurance card. Use the billing location, not the client’s home address or every state where you hold a license.Find the right guide: Choose from the available Blue Plan registration guides by service location. The index includes county-specific choices and a path to follow when no guide matches. A state listing does not cover every Blue company in that state.Follow each required plan’s out-of-network registration process. Once the payer confirms the appropriate new-record, addition, or update route, complete and submit its application or request with the required documents through that channel. Ask the payer about unclear fields before submitting. Keep a copy, the receipt, and any case number; submission is not approval.
Availity access and Blue Plan registration are separate. If a plan uses Availity, register for Availity Essentials access for your practice and complete that Local / Host Plan’s non-participating provider registration. Creating an Availity account, setting up EFT/ERA, or enrolling for transactions does not create an active provider record with the plan. Follow the plan-specific guide if it gives a different registration route.
Register the practice under its EIN/TIN and include every applicable clinician’s rendering NPI. Group clinicians do not need separate practices, but may need individual enrollment before affiliation with the group. Follow the plan-specific guide.For BCBS claims through Thrizer, the client receives any reimbursement. If a form appears to require payment to your practice or assignment of the client’s reimbursement, ask the payer how to register for member reimbursement before continuing.
BCBS registration is required even without a registration notice. A benefit check does not verify registration, and Thrizer does not complete or track it for your practice.

​
While BCBS registration is pending

You can continue charging clients while BCBS registration is pending. Thrizer will continue submitting eligible claims, though the plan may delay or deny them until registration is active.
Processing time varies significantly by Blue Plan. Follow any timing and status-check instructions in your plan-specific guide. If the payer does not publish a timeframe, retain your submission reference and follow up with the payer if no update arrives after a reasonable interval. In our experience, payers don’t always send an approval notice or other update; a lack of communication does not confirm approval.Use your submission reference when following up. Do not send a duplicate application unless the payer instructs you to. Once the practice record and required clinician affiliations are active, notify Thrizer Support.

​
TRICARE East certification

TRICARE East certification is not BCBS registration or a network-enrollment request. If you need to submit TRICARE claims in the East Region, complete the certification process for your provider type. See TRICARE East provider certification for the application path, documents to prepare, status checks, and participation-agreement requirements.

​
TRICARE West certification

If you have not signed a network agreement with TriWest, use its non-network provider application for your provider type. See TRICARE West provider certification for application links, packet submission, participation-agreement requirements, and follow-up instructions. Certification is separate from joining the network.

​
Other insurers

This guide does not ask you to register proactively with other insurers. If an insurer specifically requests provider registration, follow its instructions and notify Thrizer once approval is confirmed.

Notify Thrizer after BCBS approval

Ask each required Blue Plan to confirm that your practice record and required clinician affiliations are active, including their effective dates and any remaining steps. A submission receipt alone is not approval. Keep the confirmation and any case number.Once BCBS registration is approved, contact Thrizer support through your Thrizer account and share the plan’s approval confirmation and any related documentation. Having that documentation also helps us follow up with the payer on your behalf as needed.Thrizer will resubmit eligible claims rejected or denied because registration was missing. You do not need to identify individual claims. See claim handling after registration for details.BCBS registration does not guarantee claim approval or reimbursement.

​
If the payer asks for a W-9 or paper claim

If you need your clinician or practice W-9, contact Support through your Thrizer account to request it. Thrizer does not have or provide a CMS-1500 claim copy. Automatic claim submission does not make a copy available for you to download or mail. Follow the payer’s specific paperwork instructions. If it requires a paper claim for registration, ask the payer how to complete that requirement and contact Support about any related Thrizer claim before submitting a duplicate. For paper checks and payment options, see BCBS reimbursement. For clinician eligibility and supervision requirements, see Who can use Thrizer.
Registration gives the insurer a provider record to use when processing claims. For example, BCBSTX requires a provider record ID before electronic out-of-network claims, and Sentara requires non-participating registration and a W-9 before claims. Follow the requirements for the specific payer and provider type; these examples do not establish which plans Thrizer supports.
