Resolution/Resources

First: Verify the status of your claim before resubmitting. You can determine the status of a claim through the Palmetto GBA Online Provider Services (OPS) tool or by calling the Palmetto GBA Interactive Voice Response unit (IVR).


Online Claim Status Verification through OPS


  • All providers that have an EDI Enrollment Agreement on file may register to use this tool. If you haven’t already registered, please consider doing so.

  • Access the introductory article to learn more: Click on the 'Introducing Online Provider Services' graphic on the top of any of our main contract Web pages

  • One important consideration: Only one Provider Administrator per EDI Enrollment Agreement/per PTAN/NPI combination performs the registration process. The Provider Administrator can then grant permission to additional users related to that PTAN/NPI.

  • Billing services and clearinghouses should contact their provider clients to gain access to the system

  • Specific instructions for accessing claim status information through OPS are available in the OPS User Manual (PDF, 2.02 MB)
