How do I set billing DX codes?

Enter a billing DX code into the HHAeXchange portal before generating an invoice. Invoices generated without a billing DX code, are held in billing review with a Missing Primary Diagnosis Code error.

After entering the correct DX code, delete and re-generate the invoice.Refer to 2024 ICD-10-CM/PCS Medical Coding Reference for more information on ICD-10 codes.

Set up a Default Billing DX Code at the Agency Contract Level Closed

Agencies may set a contract-level billing DX code using the Default Billing DX Code(s) field. The system assigns this the default code unless there is a higher priority DX code assigned at the patient level. 

Go to Admin > Contract Setup > Search Contract.
Enter search parameters and then select Search. Open the contract from the search results.
Select the Billing/Collections tab.
Select the Default Billing DX Code(s) check box.
Select Add to apply a default DX billing code on the diagnosis code table.
In the Contract Default DX Code window, select the question mark (?) link to the right of the ICD field.
Search for the ICD 10 code in the Diagnosis Search window, select the code and then select Save.

By default, the system assigns the first DX code entered as the primary code. Users may manually designate the primary or admitting diagnosis code in the Contract Default DX Code window.

Set up Billing DX Codes at the Patient Contract Level Closed

DX codes entered on the Patient Contract page are second priority. If no DX code is set on the Patient Authorization page, the system searches for a Patient Diagnosis Code Override on the Patient Contract page.

Set up Billing DX Codes at the Patient’s Authorization Level Closed

DX codes entered on the Patient Authorization page receive the highest priority. This means the system assigns the DX code on this page for billing purposes even if the patient has one set on the Patient Contract page or at the agency contract level.

Select Authorization/Orders from the left menu and then select the contract listed under the Authorizations tab.
