Claim issues & disputes

Find resources and information here regarding provider disputes, including an overview of the dispute process, instructions, and details about filing online.

Blue Shield of California is committed to providing a fair and transparent provider dispute resolution process. However, the dispute process is not intended to address claim corrections, requests for claim information, or inquiries about claim decisions, procedures, and payment rules.

We may be able to help remedy a claim issue before you file a formal dispute. Your options are:

  • Correcting a claim
    Submit corrected claims within 30 working days of receiving a request for missing or additional information.
  • Making an inquiry or contacting Provider Service
    If you have questions about a specific claim, contact us. Customer service can help clarify claim decisions, procedures, and payments. They may alter original claim decisions.

If we’re not able to resolve your claim issue and you consider it necessary to file a dispute, start online.

Filing a dispute correctly is the best way to ensure a quick resolution. The dispute process is reserved for requesting payment reconsideration for claims that have been denied, paid at less than billed charges, or otherwise contested.
