What is OWCP? Understanding federal workers' compensation
OWCP stands for the Office of Workers' Compensation Programs, a division of the U.S. Department of Labor. It administers benefits for federal employees who are injured or become ill as a direct result of their job duties.
Unlike state workers' compensation systems that cover private-sector employees, OWCP is a federal program governed by the Federal Employees' Compensation Act (FECA). This means different rules, different paperwork, and different processes than what most doctors are familiar with. That's exactly why you need an OWCP doctor in Dallas who understands the system inside and out.
OWCP provides benefits including:
- Medical treatment — office visits, specialist referrals, surgery, physical therapy
- Wage replacement — compensation for lost work time
- Vocational rehabilitation — if you need to transition to a different role
- Permanent disability benefits — for lasting impairments
- Death benefits — for surviving dependents
The key: your treating physician's documentation is often the single most important factor in whether your claim is approved or denied. Poor documentation from an unfamiliar provider is one of the top reasons federal employees lose their benefits.
You have the right to choose your own OWCP doctor
This is the most important thing every federal employee needs to know: you have the legal right to choose your own treating physician under OWCP. When you're injured on the job, your supervisor or HR department may hand you a list of “approved” doctors. While you may need to visit a designated provider for an initial evaluation, you are not required to continue treatment with any agency-recommended physician.
- Your doctor works for you, not your agency
- You can choose a provider who specializes in your type of injury
- You can choose a provider who understands OWCP documentation requirements
- You can switch providers at any time without losing benefits
CA-1 vs. CA-2 claims: which do you need?
Understanding the difference between CA-1 and CA-2 claims is critical. Filing the wrong form — or filing late — can jeopardize your entire claim.
CA-1: Traumatic injury
A CA-1 form is used for injuries caused by a specific event or incident during a single work shift — slipping on a wet floor, lifting a heavy package and tearing a rotator cuff, a vehicle accident during a work route, or being assaulted on the job. Filing deadline: within 30 days of the injury for maximum benefits (you can file later, but within 3 years). The injury must be clearly tied to a specific date, time, and incident.
CA-2: Occupational disease or illness
A CA-2 form is used for conditions that develop gradually over time due to your work duties — carpal tunnel from years of sorting mail, chronic knee degeneration from standing on concrete, hearing loss from loud equipment, or peripheral neuropathy from repetitive physical labor. Filing deadline:within 3 years of when you first became aware of the condition's connection to your work. This requires medical documentation establishing a causal link — where an experienced OWCP provider makes all the difference.
Our team assists with:
- Determining the correct form for your situation
- Completing medical documentation that clearly establishes causation
- Providing objective clinical findings (range-of-motion tests, imaging referrals, diagnostic workups)
- Writing narrative medical reports that meet OWCP's evidentiary standards
- Ongoing treatment documentation that supports continued authorization
