TL;DR: Most FECA claims that run into trouble do not fail on the merits of the injury. They fail on process — the wrong form for the type of injury, a missed continuation-of-pay window, a Form CA-16 that was never issued or was issued too late, or medical evidence signed by a provider who does not meet FECA’s statutory definition of a physician. Every one of those is avoidable if you know the rule in advance. If you want the full walkthrough first, start with our OWCP guide for federal employees; this article is about the specific places people get caught.
This is general information about the FECA process, not legal advice. Deadlines and requirements are drawn from the statute and regulations cited throughout and were verified in August 2026; confirm current requirements with OWCP or your agency before relying on them.
Mistake 1: Filing the Wrong Form for the Type of Injury
FECA distinguishes between a traumatic injury — a single event or a single work shift — and an occupational disease, which develops over more than one shift from exposure or repeated activity.
A back injured lifting a box on Tuesday is a traumatic injury and belongs on Form CA-1. A shoulder worn down over four years of overhead work, or hearing loss from years of equipment noise, is an occupational disease and belongs on Form CA-2.
This is not a bureaucratic distinction. It determines the evidence you must produce, and it determines whether you are eligible for continuation of pay at all — which is the next mistake.
Mistake 2: Losing Continuation of Pay by Filing Late
Continuation of pay (COP) is the benefit that keeps your salary running while OWCP adjudicates your claim, for a period not to exceed 45 days. It is genuinely valuable, and it is the benefit most often lost by accident.
Under 5 U.S.C. § 8118, continuation of pay is contingent on filing a written claim within 30 days of the injury, and COP applies only to traumatic injuries reported on an OWCP claim form within that window.
Two consequences people miss:
- COP is for traumatic injuries only. Occupational disease claims filed on a CA-2 do not carry it. If you are out of work on an occupational disease claim, you will generally use your own leave or claim compensation on Form CA-7 while the claim is processed.
- Thirty days is short. The pattern that costs people COP is waiting to see whether the injury settles on its own. Three weeks of hoping, then a stiff back, and the window has effectively closed. File the CA-1 when it happens.
Mistake 3: Assuming the Three-Year Deadline Is the Only One
Under 5 U.S.C. § 8122, an original claim for compensation for disability or death must be filed within three years after the injury or death. If a claim is not filed within three years, compensation may still be paid where written notice of injury was given within 30 days, or where the employer had actual knowledge of the injury within 30 days of its occurrence.
People read the three-year figure and relax. That is the wrong lesson. Three years is the outer limit for the claim itself — the 30-day notice rule is what preserves your position both inside and outside that window, and the 30-day COP rule is entirely separate. Treating three years as “the deadline” is how people arrive at OWCP with a timely claim and no continuation of pay, no contemporaneous medical record, and a supervisor who does not recall the conversation.
For occupational disease, the practical difficulty is different: establishing when the clock started at all. Contemporaneous documentation of when symptoms began and when you connected them to your work is worth more than anything you can reconstruct later.
Mistake 4: Not Getting a Form CA-16 — In Time
Form CA-16 is the authorisation that lets you be treated and lets the provider bill OWCP directly rather than billing you while a claim is pending. The timing rules in 20 CFR § 10.300 are tighter than most employees realise:
- The employer should issue Form CA-16 within four hours of the claimed injury.
- If authorisation is first given verbally, the written CA-16 must follow within 48 hours.
- No CA-16 is required more than one week after the injury. After that, the agency is not obliged to issue one.
- Where issued, the form authorises treatment for 60 days from the date of injury, unless OWCP terminates the authorisation sooner.
- For an occupational disease or illness, a CA-16 may only be used with prior permission from OWCP.
One useful thing to know: under 20 CFR § 10.301, the physician designated on the CA-16 may refer you for further examination, testing or medical care, and OWCP pays those referred bills under the original authorisation. Your employer should not be issuing a second CA-16 for referred care — if someone tells you a new form is needed for a referral, that is worth questioning.
Mistake 5: Letting the Agency Choose Your Doctor
20 CFR § 10.300 provides that the employer should advise the employee of the right to select a qualified physician, excluding those excluded under subpart I. The employee may choose a physician in private practice, an HMO provider, or a physician employed by a federal agency.
In practice, an injured employee is often walked straight to whichever occupational-health contractor the agency uses, and never told there was a choice. That contractor is not neutral in the way patients assume. Being seen there for initial emergency treatment is fine; treating it as your only option is not.
Mistake 6: Medical Evidence Signed by the Wrong Provider
This is the mistake that costs the most claims, and almost nobody sees it coming — because the care was excellent and the paperwork was still rejected.
FECA defines “physician” narrowly. Under 5 U.S.C. § 8101(2), the term “includes surgeons, podiatrists, dentists, clinical psychologists, optometrists, chiropractors, and osteopathic practitioners within the scope of their practice as defined by State law”— with chiropractic coverage limited to manual manipulation of the spine to correct a subluxation demonstrated by X-ray to exist.
Nurse practitioners and physician assistants do not appear in that definition. This surprises people, particularly patients whose regular primary care has been delivered by an NP or PA for years.
There is a workable path, and it is the one we use. The FECA Procedure Manual (Part 2, Chapter 2.805.3a(1)) provides that a report prepared by a physician assistant which is countersigned by a qualified physician should be accepted as medical evidence. The report is the PA’s; the countersignature makes it admissible.
Congress has been working on this. H.R. 3170, the Improving Access to Workers’ Compensation for Injured Federal Workers Act of 2025, would allow nurse practitioners and physician assistants to certify the nature of an injury and the probable extent of disability under FECA. It was ordered reported by the House Education and the Workforce Committee by a 34–0 vote on June 25, 2025, and a Senate companion was introduced on December 2, 2025. As of August 2026 it has not been enacted, so the countersignature rule still governs. If you read an older article stating that NPs and PAs can now certify FECA disability directly, check the date.
At Innovare Tx this is handled structurally rather than by hoping: Charles Ortega, PA-C conducts the clinical work and Dr. Nathan Nguyen, MD serves as treating physician on OWCP cases, so reports going to OWCP carry a qualified physician’s signature. If you are being treated elsewhere, ask directly who is signing your CA-20 and your narrative reports. Ask before the reports are written, not after they come back.
Mistake 7: Medical Reports That Do Not Say What OWCP Needs
A correctly signed report can still be insufficient. OWCP is not simply asking whether you are hurt. It needs a physician’s reasoned medical opinion connecting the diagnosed condition to the accepted work incident or exposure.
“Patient has lumbar strain, off work two weeks” documents a diagnosis and a restriction. It does not explain why, in the physician’s opinion, the mechanism of the accepted injury produced that diagnosis. That gap is the single most common reason a claim is developed further or denied — and it is a documentation failure, not a medical one.
A useful report states the diagnosis, describes the work incident, gives the physician’s reasoned opinion on causal relationship, sets out objective findings, and specifies work restrictions. Providers who see federal cases regularly write this way by habit. Providers who see one every few years generally do not, through no fault of their own.
Mistake 8: Silence During the Claim
Two quieter errors round out the list. The first is failing to keep the file moving — Form CA-7 is how you claim compensation for wage loss, Form CA-17 is the duty status report your agency uses, and gaps in those create gaps in payment. The second is filing on paper when your agency uses ECOMP, the Department of Labor’s electronic filing system, which gives you a timestamp and a tracking record that a mailed envelope does not.
Keep your own copies of everything: every form, every report, every dated communication with your supervisor. Claims are frequently decided on a documentary record assembled months after the fact.
How We Work With Federal Employees
Innovare Tx treats federal employees under OWCP at our Addison, TX clinic. Dr. Nathan Nguyen, MD serves as treating physician, Charles Ortega, PA-C conducts the evaluation and ongoing clinical management, and Rowena Calleja, PT delivers the physical therapy — in one office, so the medical documentation and the rehabilitation record are consistent with each other. Federal employees and first responders can also see our military and first responder page.
For questions about being seen under OWCP, call (214) 233-3094 or request an appointment. Our OWCP FAQ covers what to bring to a first visit.
How long do I have to file an OWCP claim?
Under 5 U.S.C. § 8122, an original claim for compensation must be filed within three years of the injury or death. Compensation may still be payable outside that window if written notice of injury was given within 30 days or the employer had actual knowledge of the injury within 30 days. Separately, continuation of pay requires a written claim within 30 days of the injury, so the practical deadline is far shorter than three years.
What is the difference between Form CA-1 and Form CA-2?
Form CA-1 is for a traumatic injury — one caused by a specific event or during a single work shift. Form CA-2 is for an occupational disease that develops over more than one shift. The distinction affects the evidence required and whether continuation of pay is available, since COP applies to traumatic injuries.
Can a nurse practitioner or physician assistant sign my OWCP paperwork?
Not on their own under current law. The FECA definition of “physician” at 5 U.S.C. § 8101(2) does not include nurse practitioners or physician assistants. However, the FECA Procedure Manual provides that a report prepared by a physician assistant and countersigned by a qualified physician should be accepted as medical evidence. Legislation to change this (H.R. 3170) was advancing through Congress but had not been enacted as of August 2026.
How long is a Form CA-16 valid?
Under 20 CFR § 10.300, a Form CA-16 authorises treatment for 60 days from the date of injury unless OWCP terminates the authorisation sooner. The employer should issue it within four hours of the claimed injury, a verbal authorisation must be followed by the written form within 48 hours, and no CA-16 is required more than one week after the injury.
Can I choose my own doctor for a federal workers' comp injury?
Yes. 20 CFR § 10.300 provides that the employer should advise the employee of the right to select a qualified physician, other than those excluded under subpart I, and the employee may choose a physician in private practice, an HMO provider, or one employed by a federal agency. Many employees are never told this and default to the agency’s occupational-health contractor.
