What Are UB‑04 Special Bill Types?
In Texas workers' compensation, providers submit claim invoices on the UB‑04 (CMS‑1450) form. Certain services—such as emergency care, ambulance transport, or specialized procedures—require a "special bill type" code in the Form Locator 44 (Bill Type). These codes tell the Texas Department of Insurance, Division of Workers' Compensation (TDI‑DWC) how to process, reimburse, and track the claim.

Why Texas Uses Specific Bill Types
Texas law mandates that each category of medical service be identified with a distinct bill type to ensure consistent reimbursement rates and compliance with the Workers' Compensation Act. Using the correct bill type prevents claim denials, delays, and potential audits.
Key Special Bill Types for Texas Workers' Compensation
The following table lists the most common special bill types used on UB‑04 forms for Texas workers' comp claims, along with their purpose and the section of the Texas Workers' Compensation Manual where they are defined.
| Bill Type Code | Service Category | Primary Use |
|---|---|---|
| 11 | Emergency Room (ER) | Initial emergency care for work‑related injuries |
| 12 | Urgent Care | Non‑ER but immediate treatment needed |
| 13 | Ambulance Transport | Ground or air transport to a medical facility |
| 14 | Radiology Services | X‑ray, CT, MRI performed for work‑related injury |
| 15 | Physical Therapy | Rehabilitation services prescribed for injury recovery |
| 16 | Occupational Therapy | Therapy focused on return‑to‑work functional abilities |
| 17 | Surgical Procedure | Any operative intervention related to the claim |
| 18 | Prescription Drugs | Medication dispensed for the work‑related condition |
How to Choose the Correct Bill Type
Follow these steps when completing Locator 44 on the UB‑04:
- Identify the service rendered. Review the provider's notes and the claimant's injury report.
- Match the service to the bill type list. Use the table above or the official TDI‑DWC bill type reference sheet.
- Enter the two‑digit code. Place the code in Locator 44; do not add extra characters or spaces.
- Verify payer instructions. Some insurers require supplemental documentation (e.g., ambulance logs) attached to the claim.
Common Mistakes and How to Avoid Them
Even experienced billers can slip up. Below is a quick comparison of frequent errors versus best practices.
| Typical Error | Correct Approach |
|---|---|
| Using generic bill type "01" for all services | Select the specific code (e.g., 13 for ambulance) to match the service |
| Omitting Locator 44 entirely | Always complete Locator 44; a missing code triggers a manual review |
| Confusing emergency room (11) with urgent care (12) | Confirm if the patient was treated in an ER setting; otherwise use 12 |
Impact on Reimbursement Rates
Texas workers' compensation assigns fee schedules to each bill type. For example, an ER visit (Bill Type 11) is reimbursed at a higher rate than a standard office visit because it reflects the higher resource utilization. Incorrect billing can lead to:
- Reduced payment or partial denial
- Claim re‑submission fees
- Potential audit and penalties for non‑compliance
Filing Guidelines and Deadlines
After selecting the appropriate bill type, submit the UB‑04 to the employer's insurer or the self‑insured employer within the statutory timeframes:
- Initial claim filing: Within 30 days of service provision.
- Supplemental bills (e.g., follow‑up PT): Within 30 days of the service date.
- Appeals for denied bills: Within 30 days of the denial notice.
Timely filing reduces the risk of claim closure and ensures the injured worker receives prompt benefits.
