Electronic Billing Requirements

Last update
October 16, 2025

All TX providers must file their bills for injured worker treatment electronically (e-billing).

Claims administrators are required to accept providers’ e-bills and respond with electronic Explanation of Benefits (EOB).

This rule applies to both network and non-network claims.

Electronic Billing Mandate

The Texas Department of Insurance, Division of Workers’ Compensation (DWC) requires providers to bill electronically, with some exceptions.

For more information, see Texas Administrative Code Rule §133.500 on Electronic Formats for Electronic Medical Bill Processing and Rule §133.501 on Electronic Medical Bill Processing.

Health care providers in the state should e-bill unless they meet the exception criteria below.  

Exemptions to Mandatory e-Billing

e-Billing is required for all providers. However, a provider may be exempt from e-billing if one of the following applies:

  • The provider has fewer than 10 full-time employees
  • The provider has treated 32 or fewer injured workers in the previous calendar year, or
  • The provider can demonstrate that setting up e-billing would cause an unreasonable financial burden and can submit financial statements and other documentation as proof of implementation costs.

If a provider claims one of these exemptions, the DWC may ask for proof. The provider must submit all supporting documentation within 15 days of the DWC’s request.
