Washington Medicaid E-Claims
In the E-Claims window click Add. Set up the clearinghouse as shown above.
The Tax ID Number should be 9 digits. To find the Tax ID Number, log in to the ProviderOne web portal and locate the 7-digit ProviderOne ID at the top of the page, then tack two trailing zeros at the end to make it 9-digits.
Click OK to save.
In the Main Menu, click Lists, Insurance Carriers and add a new carrier using the information below.
Make sure ALL Washington Medicaid insurance plans use the WA State HCA carrier, and the insurance filing code Medicaid (Insurance Plan).
In the Manage Module, click Send Claims. Select the claims for Washington Medicaid only, then click the Send E-Claims dropdown and select Washington Medicaid from the list.
In a file browser, go to C:\Washington Medicaid\. Change the extensions on the newest files from txt to dat. Older files should already have a dat extension, so it should be easy to tell which files are new. You can also look at the file date and time information to determine which files are new.
Go to www.waproviderone.org/edi and log in using the provider credentials.
On the left, click the On-line Batch Claims Submission (837) link.
For each new dat file created, click the browse button, and locate the file, then click Upload.
After 15 minutes, the files should register in ProviderOne.
If there are errors at this point, email email@example.com. If no errors are indicated, then the file format is correct, but that does not mean that each claim will be paid. The morning after the files are uploaded, use the Claim Inquiry link to look up each claim and verify that it will be paid.
