Dispute a claim decision online – frequently asked questions

You can now submit disputes involving your commercial, Shared Advantage® and BlueCard® claims through Provider Connection, in addition to using the existing mail-in process.
  • Can anyone submit disputes on Provider Connection?

    You need to be registered, signed in, and have access to claims on Provider Connection to submit disputes online. You can submit and view disputes for claims connected to the Tax IDs that you have access to. If you need additional access, talk to your Provider Connection account manager.

  • Is the dispute review process different when you submit online or by mail?

    The dispute review process is the same whether you submit online or by mail. You may receive the determination sooner if you submit online.

  • What kinds of disputes can be submitted online?

    You can submit disputes online for commercial, Shared Advantage®, Federal Employee Program (FEP), BlueCard®, Promise Medi-Cal, and Medicare claims.  File disputes for Promise Medicare, Cal Medi-Connect, Medicare prescription drug plan (PDP), and dental plan claims by mail.

  • How do I initiate a dispute online?

    Search for a claim related to your dispute. Once you’ve selected a claim, you can start the dispute directly on the claim page. Click the "Resolve claim issue or dispute" link at the top of the page. Or, if you already know the claim number, you can enter it on the Claim issues & disputes page.

  • Can I submit initial and final disputes online?

    Yes. For each new submission, whether initial or final, BlueShield will assign a new case number.

  • Are there rules about bundling?

    Yes. Bundles must be for the same type of issue. There are two ways to submit depending on the number of claims you are bundling and the plan type:

    • Entering claim numbers - when you have up to 50 claims.
    • Uploading a CSV file. All claims in a bulk dispute must be for the same or similar issue.


    For all bulk disputes: 

    • Write one description.
    • Attach the documents once.
    • We will create bulk cases for all of your claims (except for BlueCard® claims where multiple disputes will be created).
    • You will receive an acknowledgement and determination letter for each case we create.
    • You will be able to view and download all documents from the Submitted disputes page.


    You can only bundle Federal Employee Program (FEP) and BlueCard® claims if they’re for services provided to the same member. Also, Medicare claims for non-contracted providers where we have to collect waivers of liability can’t be submitted in a bundle. 

  • How do I create a CSV file with a list of claims for a bulk dispute?

    In Excel, you can export or save your file as a comma delimited CSV. Be sure to include: 

    • Claim numbers in the first column
    • A header row at the top


    Label the first column “Claim Number” or “ICN” in the header. Additional columns can be included as needed (optional, will not be verified).

    Claim numbers must match 
    The claim numbers from the first column of your list will be checked against our records.

    For your reference 
    You can use this template as an example to create a spreadsheet of up to 500 claims for the same plan type.

  • Is there a way to check the plan types on my claim list?

    Upload your claim list (with up to 3000 claims). We’ll return your list with notes on the plan types we find. You can then organize your list by plan type to submit for processing. 

  • What files can I submit online?

    You can submit up to 20 PDF, DOC, and XLS files of up to 50 MBs for most claims. Upload up to five files at a time. 

    You will be asked to provide additional information for each file, designating them as medical records, contract/pricing, itemized bills or other. Please include a description for each file you attach. 

    For BlueCard® claims you can submit up to 20 PDF files of up to 10 MBs. Note, we may need to share these files with the member’s out-of-state plan. Files that do not meet these requirements cannot be uploaded.

  • What should I do if I’m having problems uploading large files?

    Large files may take longer to upload on slow connections. If you are experiencing issues, wait a few minutes, then resubmit. You can also try uploading one file at a time instead of multiple files at once. If you’re still having trouble, contact us.

  • I need to add more documents to my dispute, what do I do?

    You can add supporting documents to disputes that are still in the open or pending status. Go to the Submitted disputes page. Look for the Add documents link in the status column on the right. It will be there as long as the dispute is pending.

  • Where can I see status for disputes I have submitted?

    Look up dispute status and retrieve letters for a dispute you submitted in the past on the Submitted disputes page.

    • Search and filter the list of disputes to find your dispute by case or claim number, member's last name, dates of service, or submission date. Disputes submitted online or by mail are on different tabs. 
    • On a dispute record, you’ll find copies of the letters you’ve received via email, such as the determination letter and acknowledgement letter. 
    • You can view and download determination letters or claim list response for bundled dispute submissions. 
    • Disputes submitted by mail can be searched on a separate tab.
