What Healthcare Providers Need to Know

Our goal is to help injured employees return to health, and medical providers are essential. Here's some key information and instructions.

Best Practice

Healthcare providers prioritize taking care of injured employees, so our goal is to minimize paperwork needed to provide services and billing. This information is specifically for healthcare providers.


If you’re a provider who needs preauthorization for non-emergency healthcare services or treatment, please follow these steps: 

  1. Review the list of treatments requiring approval before providing care: 
  2. Complete the appropriate request form: 
  3. Fax the request form with supporting clinical documentation to 888-777-8272.

Treatment guidelines  

The Texas Department of Insurance has adopted the Official Disability Guidelines (ODG) for workers' compensation medical treatment in Texas. The ODG provides evidence-based guidelines to ensure appropriate treatment. The Division of Workers’ Compensation also requires MDGuidelines for disability management and return-to-work. Healthcare providers and payors are required to use both the ODG and MDGuidelines.  

Billing for medical and pharmacy  

The Fund works with two different companies to handle billing, which in most cases must be done via electronic submission. Here are some key steps to ensure bills are processed quickly. Remember, healthcare providers with fewer than 10 employees and for whom workers’ compensation represents less than 10% of their business are not required to submit electronically, though it is recommended.  

For complete, current billing instructions for health care providers and hospitals, visit the Texas Department of Insurance general billing guide.

Checking claim status 

Call 800-482-7276 to see if we have a claim on file or to get a claim number. You will need the injured employee's full name and/or Social Security number. 

HIPAA and workers’ compensation  

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) does not apply to workers' compensation insurers, workers' compensation administrative agencies, or employers when disclosing protected health information (PHI) as required by state law for workers' compensation purposes. 

State law requires workers' compensation system participants to disclose an injured employee’s protected health information (PHI) as necessary to process or adjudicate claims or to coordinate care under the workers' compensation system. System participants that make PHI disclosures to other workers' compensation participants as required by the DWC rules are, therefore, exempt from HIPAA rules regarding those disclosures.
