Every OWCP term, explained.
OWCP — the Office of Workers' Compensation Programs — uses its own vocabulary of forms, programs, medical evaluations, and benefit types. This glossary defines 37 of the most-used OWCP terms in plain language, organized by category, with cross-links to related concepts. Bookmark this page — you'll come back to it.
Programs & Agencies
The federal programs and agencies that administer workers' compensation for federal employees.
OWCP is the U.S. Department of Labor agency that administers four federal workers' compensation programs covering federal civilian employees, energy workers, longshore workers, and coal miners. It processes claims, authorizes medical care, and pays benefits.
OWCP operates four divisions: DFEC (federal employees), DEEOIC (energy/atomic workers), DLHWC (longshore workers), and DCMWC (coal miners). For most federal civilian employees, OWCP-enrolled providers like NuThera bill OWCP directly for treatment of accepted conditions.
The DOL is the cabinet-level federal agency that oversees worker protections, including OWCP. When you see 'DOL-enrolled provider' or 'DOL forms,' it refers to the Department of Labor's authority over federal workers' compensation.
See also:OWCPFECA is the 1916 federal law that provides workers' compensation coverage for federal civilian employees injured or made ill on the job. It guarantees medical care, wage-loss benefits, vocational rehabilitation, and survivor benefits — and gives employees the right to choose their own treating physician.
FECA covers about 2.6 million federal civilian employees across all agencies (USPS, VA, TSA, DoD civilian, SSA, etc.). It is administered through OWCP's DFEC division. Claims are not adversarial — there is no fault to prove, only that the injury or condition is work-related.
DFEC is the OWCP division that administers FECA — the workers' compensation program for federal civilian employees. If you work for USPS, VA, TSA, DoD as a civilian, or any other federal agency and are injured on the job, your claim is processed by DFEC.
DEEOIC is the OWCP division that administers EEOICPA — compensating Department of Energy nuclear weapons workers, uranium workers, atomic weapons employees, and Nevada Test Site workers for radiation-induced cancers, beryllium disease, chronic silicosis, and toxic-exposure illnesses.
Nevada is a major DEEOIC population center because of the Nevada Test Site (now Nevada National Security Site). DEEOIC pays a tiered lump-sum plus ongoing medical benefits for covered conditions.
EEOICPA is the 2000 federal law that established compensation for Department of Energy workers and contractors exposed to radiation, beryllium, or other toxic substances during the Cold War nuclear weapons program. Administered through DEEOIC.
See also:DEEOICDCMWC is the OWCP division that administers the Black Lung Benefits Act — providing medical care and monthly benefits to coal miners totally disabled by pneumoconiosis (black lung disease) and to surviving dependents.
See also:OWCPLHWCA provides workers' compensation for maritime workers — longshoremen, ship-repairers, harbor construction workers — and for civilian employees of the U.S. military overseas under the Defense Base Act extension. Administered through OWCP's DLHWC division.

Forms & Filings
Official forms used to file, support, and document an OWCP claim.
Form CA-1 is the official notice a federal employee files when injured by a single specific event during a single workday or shift — for example, a fall, a back strain lifting a package, or a vehicle accident on duty. It must be submitted within 30 days of the injury.
Once filed, the CA-1 entitles you to 45 days of Continuation of Pay (COP) for time lost from work due to the injury, plus medical care under OWCP. Filing is done through your supervisor or directly via the ECOMP portal.
Form CA-2 is filed when a federal employee's condition develops over time from repeated work exposure rather than a single traumatic event — for example, carpal tunnel syndrome from years of typing, hearing loss from prolonged noise exposure, or chronic respiratory disease from chemical exposure.
CA-2 claims require a stronger causation narrative than CA-1 because the link between work and disease is cumulative rather than incident-specific. This is where a treating physician's detailed medical reasoning becomes critical.
Form CA-2a is filed when symptoms from a previously accepted OWCP injury return after a period of recovery — for example, a back injury accepted two years ago that flares up again. The form re-establishes the causal connection to the original work injury without requiring a new claim.
Form CA-7 is filed to claim wage-loss compensation when you have used all 45 days of Continuation of Pay (COP) but are still unable to work due to your accepted OWCP injury. It establishes ongoing TTD or TPD benefits.
Form CA-16 is an authorization your supervisor issues — typically within 4 hours of a reported injury — that allows the first 60 days of medical treatment from the provider of your choice. It guarantees the chosen physician will be paid by OWCP regardless of the eventual claim decision.
CA-16 is critical: bring it (or have your supervisor send it) to your first OWCP visit so billing isn't disputed later. NuThera accepts CA-16 authorizations directly from federal supervisors.
See also:CA-1Form CA-17 is completed by the treating physician at every OWCP visit, documenting the employee's current work restrictions, what physical activities they can and cannot perform, and whether they can return to full or modified duty. It drives wage-loss benefit decisions.
Gaps in CA-17 documentation are one of the most common reasons OWCP pauses or denies benefits. NuThera produces an updated CA-17 at every visit so the file stays current.
Form CA-20 is a detailed clinical progress report the treating physician provides to OWCP — typically when requested by the claims examiner. It documents diagnosis, treatment plan, response to care, prognosis, and the medical reasoning that ties the condition to work.
Form OWCP-957 is used to claim reimbursement for travel expenses incurred while obtaining authorized medical care for an OWCP-accepted condition — including mileage, parking, and overnight lodging when treatment requires travel.
See also:OWCPECOMP is the U.S. Department of Labor's online portal where federal employees file OWCP claims (CA-1, CA-2), upload supporting medical documentation, check claim status, and communicate with claims examiners. It replaces the older paper-only filing process.
All new OWCP claims should be filed through ECOMP at ecomp.dol.gov. Your supervisor's signature is captured electronically. Acceptance into the system creates your claim number (also called an ICN).
Forms EE-1 (employee) and EE-2 (survivor) are the initial claim forms for the DEEOIC program — used by Department of Energy nuclear weapons workers, uranium workers, and their survivors to apply for compensation for radiation-induced or toxic-exposure illnesses.
Medical & Clinical Terms
Clinical examinations, evaluations, and assessments referenced throughout the OWCP claim process.
Schedule Award
# linkA Schedule Award is OWCP compensation for permanent partial impairment of a specific body part — eye, ear, arm, leg, hand, foot, or hearing. It is paid as a fixed number of weeks of compensation based on the percentage of impairment determined by a physician using the AMA Guides to the Evaluation of Permanent Impairment.
Schedule Award evaluations are highly technical. The treating physician (or specialist) measures impairment using the AMA Guides 6th Edition, applies the FECA-specific schedule of weeks per body part, and submits the calculation to OWCP. NuThera handles Schedule Award evaluations in-house.
Causation Narrative
# linkA causation narrative is a detailed medical statement from the treating physician explaining — in clinical reasoning — exactly how a specific work activity or exposure caused, contributed to, or aggravated the employee's condition. It is the single most important medical document in establishing an OWCP claim.
Insufficient causation documentation is the #1 reason OWCP claims are denied. A strong causation narrative cites specific work activities, dates, mechanisms of injury, clinical findings, and medical literature when relevant.
MMI is the point at which an injured worker's medical condition has stabilized — further significant improvement is not expected with continued treatment. MMI does not mean fully recovered; it means recovered as much as medically possible. Schedule Award evaluations can only be performed once MMI is reached.
An IME is a medical examination conducted by a physician selected by an outside party — typically OWCP, the employing agency, or a third-party administrator — rather than the employee's treating physician. The examiner provides an opinion on diagnosis, causation, work restrictions, or impairment for use in claim decisions.
When an IME conflicts with your treating physician's findings, your physician should produce a detailed rebuttal narrative addressing the IME report point-by-point. NuThera handles IME rebuttals.
A SECOP is OWCP's term for a Second Opinion Examination — a specific type of IME where OWCP refers the claimant to a non-treating physician for an independent assessment, typically to resolve questions about ongoing work restrictions, MMI, or appropriateness of continued treatment.
An AME is a physician selected by mutual agreement between the parties — typically the claimant and the employing agency or OWCP — to conduct a definitive medical evaluation when there is a dispute. The AME's findings carry significant weight in resolving the disagreement.
An IMR is a third physician brought in when the treating physician's opinion and a SECOP examiner's opinion conflict on a specific medical question. The IMR provides an impartial determination, and the IMR's opinion typically becomes the controlling medical evidence.
A Nurse Case Manager is a registered nurse assigned by OWCP (or sometimes the employing agency) to coordinate the injured worker's care — verifying treatment authorization, communicating between physician and claims examiner, and monitoring return-to-work progress.
See also:MCMA Medical Case Manager (sometimes used interchangeably with NCM) coordinates the medical aspects of an OWCP claim — appointment scheduling, documentation routing, and communication between the treating physician's office and OWCP. MCMs do not make medical decisions.

Process, Benefits & Appeals
Steps, benefit types, and appeal pathways within the federal workers' compensation system.
COP is up to 45 calendar days of paid leave that a federal employee can take after a traumatic injury (CA-1) without using personal sick or annual leave. Pay continues at the regular rate from the employing agency. After COP expires, wage-loss benefits transition to OWCP via Form CA-7.
TTD is wage-loss compensation paid by OWCP when an injured worker cannot perform any work at all due to their accepted condition. Paid at 66.67% of pre-injury wage (75% if the worker has dependents). Continues until the worker can return to some form of work or reaches MMI.
TPD is wage-loss compensation paid when an injured worker can perform some work at reduced capacity or hours due to their accepted condition. OWCP pays 66.67% (or 75% with dependents) of the difference between the pre-injury wage and current earning capacity.
PPD describes a permanent impairment that does not totally disable the worker — for example, partial loss of use of a hand or chronic limited range of motion. PPD typically results in a Schedule Award rather than ongoing wage-loss benefits.
LWEC is OWCP's calculation of how much an injured worker's earning ability has been permanently reduced by an accepted condition. The LWEC determination drives long-term wage-loss compensation. It compares the pre-injury job to the worker's post-injury capacity.
Reconsideration
# linkA reconsideration is a request that OWCP review and reverse a previous claim decision based on new evidence (typically updated medical documentation or a supplemental causation narrative). Must be filed within 1 year of the original decision. The same OWCP office that issued the original decision conducts the review.
Reconsideration is the most common appeal pathway because new medical evidence is often available after the original denial. Strong supplemental causation narratives are central to successful reconsiderations.
ECAB is the federal appeals body that conducts the final administrative review of OWCP claim decisions. Appeals must be filed within 180 days of the final OWCP decision. ECAB review is based on the existing record — no new evidence is permitted at this stage.
See also:ReconsiderationOral Hearing
# linkAn oral hearing is an appeal option where the claimant appears (in person or by phone) before an OWCP hearing representative to present their case and submit additional evidence. Must be requested within 30 days of the original denial and is conducted by OWCP's Branch of Hearings and Review.
Review of the Written Record
# linkA review of the written record is an appeal option similar to an oral hearing but conducted entirely on the documents submitted — no in-person testimony. Must be requested within 30 days of the denial. Useful when the case turns on documentation rather than testimony.
Glossary FAQ.
What's the difference between a CA-1 and a CA-2?
A CA-1 is filed for traumatic injuries — a single specific event that happened in one workday or shift, like a fall or lifting injury. A CA-2 is filed for occupational diseases that develop over time from repeated exposure, like carpal tunnel syndrome or hearing loss. The medical evidence required is different: CA-1 needs proof of the specific event; CA-2 needs a detailed causation narrative connecting cumulative work activity to the disease.
What's the difference between an IME and a SECOP?
IME (Independent Medical Examination) is the general term for any examination by a non-treating physician selected by an outside party. SECOP (Second Opinion Examination) is OWCP's specific term for an IME they request — typically to resolve questions about ongoing work restrictions, MMI, or appropriateness of continued treatment. All SECOPs are IMEs, but not all IMEs are SECOPs.
How do I know which OWCP form I need?
If you're filing a new claim: CA-1 (traumatic injury) or CA-2 (occupational disease). If you need authorization for the first 60 days of treatment: CA-16. If you've been off work past your 45 days of COP: CA-7. If your physician needs to update OWCP on your work status: CA-17. If a claims examiner requests a detailed report: CA-20. If your old injury has flared up: CA-2a.
What does MMI mean for my OWCP claim?
MMI (Maximum Medical Improvement) is the point where your condition has stabilized — further significant medical improvement is not expected. MMI does not mean you've fully recovered. Reaching MMI is what makes you eligible for a Schedule Award if you have permanent impairment. Until MMI, OWCP continues paying for active treatment.
Where can I find these forms to download?
Official OWCP forms are at the U.S. Department of Labor website (dol.gov/agencies/owcp). NuThera also publishes plain-language companion guides for the most common forms (CA-1, CA-2, CA-16, CA-17, CA-20) on our /owcp/forms page, plus our own Work Status / Restrictions form used at every visit.
