Treatment Preauthorization

Last update
October 15, 2025

Texas providers must obtain preauthorization before treating injured workers.

Preauthorization rules differ for non-network and network claims. Follow the steps below to determine when preauthorization is required and how to request it.  

Treatment Preauthorization

Preauthorization is a prospective utilization review in which a provider must request a claims administrator to authorize proposed treatment or healthcare as to whether it is medically necessary for a compensable injury.

If the claims administrator approves the provider’s proposed treatment or health care, the provider may proceed with treatment. The provider may follow the appeal process if the carrier issues an adverse determination, denying the proposed treatment.  

Non-Network Preauthorization

Providers must follow specific steps to obtain preauthorization for non-network services.

Step 1: Determine if the Service Requires Preauthorization

Before treating an injured worker, providers must confirm whether the service requires preauthorization.

Providers must request and obtain preauthorization before delivering any of the following non-emergency services:

  • Inpatient hospital admissions
  • Outpatient or ambulatory surgery
  • Spinal surgery
  • Work conditioning or work hardening
  • Physical or occupational therapy beyond six early visits
  • Investigational or experimental services
  • Psychological testing and psychotherapy
  • Diagnostic studies over $350
  • Durable medical equipment over $500 per item
  • Chronic pain management programs
  • Drugs not included in the Closed Formulary
  • Treatments exceeding or outside the Official Disability Guidelines (ODG)
  • Required treatment plans

Step 2: Request Preauthorization

Providers must submit their request for preauthorization to the claims administrator.

Claims administrators must respond within 3 working days of receiving the request. Failure to adhere to this timeline results in an administrative violation.

Once approved, a preauthorization cannot be revoked.

Providers can request preauthorization using any of the following methods:

  • Telephone
  • Facilimile
  • Electronic transmission

For more information, providers can refer to the Non-Network Preauthorization/Concurrent Review Process diagram on the DWC website.

Adverse Determinations

If the claims administrator issues an adverse determination, providers the preauthorization request:

  • The URA must give providers a reasonable opportunity to discuss the proposed treatment before finalizing the denial
  • Providers may request reconsideration for adverse determinations within 30 days of receiving the denial.

Claims administrators must respond to reconsideration requests within 30 days.

If the denial stands, providers may file a medical dispute with the DWC under Labor Code §413.031.

Network Preauthorization

Providers must refer to the network contract for preauthorization requirements before treating injured workers within workers’ compensation Health Care Networks (HCNs).

If the injured worker’s employer participates in a network, the injured worker must select a treating doctor from the network’s approved provider list.

Step 1: Review the Network Contract

Providers must review their network contract to identify which services require preauthorization. The network establishes these requirements, which must comply with:

Step 2: Request Network Preauthorization

Providers are required to adhere to the network's preauthorization process. This includes submitting requests in the specified manner, providing all necessary medical documentation, and meeting all network-defined timelines.

If the network denies a request, providers must follow the network’s appeal procedures.

Subsection Text

(a)  In this section, "investigational or experimental service or device" means a health care treatment, service, or device for which there is early, developing scientific or clinical evidence demonstrating the potential efficacy of the treatment, service, or device but that is not yet broadly accepted as the prevailing standard of care.

(b)  The commissioner by rule shall specify which health care treatments and services require express preauthorization or concurrent review by the insurance carrier.  Treatments and services for a medical emergency do not require express preauthorization.

(c)  The commissioner's rules adopted under this section must provide that preauthorization and concurrent review are required at a minimum for:

(1)  spinal surgery, as provided by Section 408.026;

(2)  work-hardening or work-conditioning services;

(3)  inpatient hospitalization, including any procedure and length of stay;

(4)  physical and occupational therapy;

(5)  outpatient or ambulatory surgical services, as defined by commissioner rule; and

(6)  any investigational or experimental services or devices.

(c-1)  Notwithstanding Subsection (c)(2), the commissioner by rule may exempt from preauthorization and concurrent review work-hardening or work-conditioning services provided by a health care facility that is credentialed by an organization designated by commissioner rule.

(d)  The insurance carrier is not liable for those specified treatments and services requiring preauthorization unless preauthorization is sought by the claimant or health care provider and either obtained from the insurance carrier or ordered by the commissioner.

(e)  If a specified health care treatment or service is preauthorized as provided by this section, that treatment or service is not subject to retrospective review of the medical necessity of the treatment or service.

(f)  The division may not prohibit an insurance carrier and a health care provider from voluntarily discussing health care treatment and treatment plans and pharmaceutical services, either prospectively or concurrently, and may not prohibit an insurance carrier from certifying or agreeing to pay for health care consistent with those agreements.  The insurance carrier is liable for health care treatment and treatment plans and pharmaceutical services that are voluntarily preauthorized and may not dispute the certified or agreed-on preauthorized health care treatment and treatment plans and pharmaceutical services at a later date.
