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 the plans Thrizer currently identifies as requiring provider pre-registration: BCBS umbrella plans. The links below are individual registration guides, not a complete list of Blue companies. If your Blue plan isn’t listed, use the fallback instructions below.
The practice completes registration, not the client. Follow the two steps below. Already registered? Notify Thrizer.
1

Register your practice

Have your practice’s Tax ID (TIN), each clinician’s individual NPI, and the practice or claim-service address ready. 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.Choose a guide for your required plan:Alabama (AL) — BCBS · Arizona (AZ) — AZ Blue · Arkansas (AR) — Blue Cross · California (CA) — Blue Shield and Anthem Blue Cross, both required · Hawaii (HI) — HMSA · Idaho (ID) — Blue Cross · Illinois (IL) — BCBS · Iowa (IA) — Wellmark · Louisiana (LA) — Louisiana Blue · Michigan (MI) — BCBS · Minnesota (MN) — Blue Cross · Mississippi (MS) — BCBS · Montana (MT) — BCBS · New Mexico (NM) — BCBS · North Carolina (NC) — Blue Cross NC · Oklahoma (OK) — BCBS · South Carolina (SC) — BlueCross · South Dakota (SD) — Wellmark · Texas (TX) — BCBS.Plans serving multiple locations: Anthem — Colorado (CO), Connecticut (CT), Georgia (GA), Indiana (IN), Kentucky (KY), Maine (ME), Missouri (MO), Nevada (NV), New Hampshire (NH), New York (NY), Ohio (OH), Virginia (VA), Wisconsin (WI) · Highmark · Independence Blue Cross. Check the guide’s service-area instructions; a state listing does not cover every Blue company in that state.No matching guide? Sign in to Availity Essentials, open Payer Spaces, and look for your Blue plan’s non-participating-provider registration process. If it isn’t available, contact the payer for its registration route. An Availity account, EFT/ERA setup, or transaction enrollment alone does not complete provider registration.
Use the BCBSA company directory as a backup. Enter the ZIP code for your practice or claim-service location in Find Your Local BCBS Company, not the three-character prefix from the client’s insurance card. Complete a separate registration with every company returned.If the service location is unclear, including for telehealth, ask BlueCard provider services which ZIP code to use. Some Blue companies have names without “BCBS”; the directory also helps confirm their affiliation.Ask the payer: “We need to establish a nonparticipating provider record for claims processing, not join your network. Which process should our practice use?”
Register the practice under its 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.

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 approval

You can continue charging clients while registration is pending. Thrizer will continue submitting eligible claims, though the payer may delay or deny them until registration is active.
Registration usually takes up to one month to be confirmed, though timing varies by payer. Contact the payer for updates on your application.Ask each required payer to confirm that your practice record and required clinician affiliations are active. A submission receipt alone is not approval. Keep the confirmation and any case number.Once registration is approved, contact Thrizer support through your Thrizer account and share the payer’s approval confirmation and any related documentation. 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.Registration does not guarantee claim approval or reimbursement.
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.
