Medical billing

The rules in 28 Texas Administrative Code (TAC) Chapter 133, Subchapters A, B, and G apply to injured employees not subject to a workers' compensation health care network (non- network claims), and health care services provided to injured employees subject to a workers' compensation health care network established under Insurance Code Chapter 1305 (network claims) with any exceptions provided by the applicable rules.

Texas Labor Code Section 408.0251 requires health care providers and insurance carriers to submit and process medical bills electronically. The rules in Chapter 133, Subchapter G (relating to electronic medical billing, reimbursement, and documentation) outline the transaction sets required for electronic medical bill processing and provide limited exemptions from the electronic medical bill processing requirements.

When a medical bill cannot be submitted electronically, the bill can be submitted on a paper form.

Health care provider billing procedures (28 TAC, Chapter 133, Subchapter B)

A medical bill must be submitted:

  • In the name of the licensed health care provider who provided the health care, or who directly supervised an unlicensed individual who provided the health care.
  • In an amount that does not exceed the health care provider’s usual and customary charges.
  • Using the correct billing codes from the applicable DWC fee guidelines in effect on the date of service.

With few exceptions, the filing deadline for Texas workers' compensation medical bills is 95 days from the date of service. If a medical bill for payment is not submitted timely, the health care provider loses the right to reimbursement of that medical bill.

Exceptions to the 95-day filing deadline are provided in Texas Labor Code Section 408.0272
