Form OWCP-5b is the federal Work Capacity Evaluation for Cardiovascular and Pulmonary Conditions, and the treating physician must complete it to tell the U.S. Department of Labor exactly what work the injured employee can and cannot do. The form drives almost every major decision in a federal workers’ compensation claim, from continuation of pay to job offers, vocational rehabilitation, and loss-of-wage-earning-capacity (LWEC) determinations. A poorly completed OWCP-5b can stop benefits, trigger a 5 U.S.C. § 8106(c) penalty for refusing suitable work, or sink an otherwise valid claim.
The Office of Workers’ Compensation Programs (OWCP) inside the U.S. Department of Labor uses OWCP-5b under the Federal Employees’ Compensation Act, the Longshore and Harbor Workers’ Compensation Act, the Energy Employees Occupational Illness Program, and the Black Lung Benefits Program. Each program reads the form a little differently, but the legal weight is the same: it is a sworn medical opinion, and under 20 C.F.R. § 10.331 it must be rationalized, signed, and based on objective findings.
According to OWCP’s most recent Annual Report to Congress, the FECA program paid more than $3 billion in wage-loss and medical benefits last year, and roughly 1 in 7 long-term disability files involve a cardiovascular or pulmonary condition that requires an OWCP-5b on file before benefits continue.

What Form OWCP-5b Is and Why It Exists
Form OWCP-5b is the standardized medical questionnaire OWCP sends to a treating physician when the accepted condition involves the heart, blood vessels, or lungs. The form forces the doctor to translate medicine into work terms: hours of sitting, pounds lifted, exposure to fumes, and tolerance for stress. Without those work-term answers, the claims examiner cannot decide whether the employee can return to the date-of-injury job, a modified job, or no job at all.
The form exists because Congress, through 5 U.S.C. § 8123, requires the injured worker to submit to medical examination and to provide rationalized medical evidence. The plain-English meaning is that a doctor’s note saying “patient cannot work” is not enough. The consequence of skipping the form or sending a vague letter is suspension of compensation under 20 C.F.R. § 10.323. A common misconception is that any cardiologist note will do; in reality, OWCP almost always requires the OWCP-5b specifically.
How OWCP-5b Differs From OWCP-5a and OWCP-5c
OWCP publishes three Work Capacity Evaluation forms, and picking the wrong one delays the claim. OWCP-5a covers psychiatric and psychological conditions, OWCP-5b covers cardiovascular and pulmonary conditions, and OWCP-5c covers musculoskeletal conditions. The consequence of using OWCP-5c for an accepted myocardial infarction claim is that the form will be returned, the file will sit, and benefits may be interrupted. A real-world example is a postal worker with both a back strain and hypertensive heart disease, who needs both OWCP-5c and OWCP-5b on file. A common misconception is that the cardiologist can answer the musculoskeletal form; the FECA Procedure Manual requires a specialist match.
Which OWCP Programs Use the 5b
The 5b is most common in FECA cases involving federal civilian employees, but it also appears in Longshore claims for shipyard workers with occupational asthma and in Energy Employees claims for nuclear weapons workers with chronic beryllium disease. Black Lung claims rely more on the CM-988 pulmonary report, but adjudicators may still accept a completed 5b. The consequence of submitting a 5b in the wrong program is usually a request for the program-specific form. A useful example is a DOE contractor with silicosis who files under EEOICPA and is asked for a 5b to support impairment.
Who Can Complete OWCP-5b
Only a “physician” as defined in 5 U.S.C. § 8101(2) can sign OWCP-5b. That definition includes medical doctors, doctors of osteopathy, and certain specialists, but it excludes chiropractors for cardiopulmonary issues and excludes nurse practitioners and physician assistants from signing as the attending physician of record. The consequence of a non-qualifying signer is automatic rejection of the form. A common misconception is that a PA’s signature is fine if the supervising MD co-signs; OWCP requires the MD to be the actual examining physician.
The treating physician should be board-certified in cardiology, pulmonology, internal medicine, or occupational medicine when the condition is complex. A general practitioner can complete the form for straightforward cases, but for an accepted ischemic heart disease claim, OWCP often requests a specialist update. The example: Dr. Patel, a board-certified pulmonologist, completes the 5b for a federal firefighter with smoke-inhalation lung injury and includes pulmonary function test (PFT) values, which strengthens the rationalized opinion.
Second Opinion and Referee Examiners
When OWCP doubts the treating physician, it can order a second opinion exam under 20 C.F.R. § 10.320. When the second opinion conflicts with the treating doctor, OWCP must use a referee or “impartial” specialist under 5 U.S.C. § 8123(a). The referee’s OWCP-5b carries special weight under ECAB precedent such as Carl Epstein, 38 ECAB 539. The consequence of refusing a directed exam is suspension of benefits. A misconception is that the employee can pick the referee; in reality, OWCP selects from the Physicians Directory System.
Step-by-Step: Filling Out Each Section of OWCP-5b
The form is two pages, but every line carries weight. Going line by line prevents the most common rejections.
Section 1: Claimant Identification
This block asks for the employee’s full legal name, OWCP file number, date of injury, and accepted conditions. The OWCP file number is a nine-digit number assigned when the CA-1 or CA-2 was filed. The consequence of an incorrect file number is the form going to the wrong file and triggering a missed deadline. A real-world example: a VA nurse named Maria writes her Social Security number instead of her OWCP number, and the form sits for six weeks. The fix is to confirm the file number on any ECOMP correspondence.
The “accepted conditions” line should match the acceptance letter word-for-word. If the doctor writes “heart attack” but OWCP accepted “acute myocardial infarction, ICD-10 I21.9,” the examiner may treat the form as off-claim. The consequence is delayed benefits while clarification is requested. A useful misconception to bust: writing more conditions than accepted does not expand the claim; conditions must be added through a separate CA-2a recurrence claim or a written expansion request.
Section 2: Diagnosis and Objective Findings
The physician must list the current diagnosis using ICD-10 codes and the objective findings supporting it. Objective findings include EKG results, echocardiogram ejection fraction, stress test METs, PFT values like FEV1 and FVC, arterial blood gases, and imaging reports. The consequence of leaving this section blank is a “not rationalized” rejection under ECAB cases such as John W. Montoya, 54 ECAB 306. The example: Dr. Chen attaches a recent echo showing EF of 35% to support a permanent restriction on lifting over 20 pounds.
A common misconception is that subjective complaints of chest pain alone justify restrictions. Under FECA Bulletin 12-02, restrictions must trace to objective evidence. The plain-English rule is “show your work.” Without objective backup, OWCP may reduce or terminate compensation.
Section 3: Physical Capacity (Hours and Activities)
This is the heart of the form. The physician must check the maximum hours per workday the employee can sit, stand, walk, lift, climb, bend, and tolerate environmental exposures. The choices are usually 0, 1–2, 2–4, 4–6, 6–8, or 8 hours. The consequence of checking “8 hours” for every line on a serious cardiac patient is that the claims examiner will treat the employee as fully recovered and stop wage-loss benefits. A real-world example: a TSA officer named James, post triple-bypass, is restricted to 4 hours of standing and no lifting over 10 pounds, which clearly excludes his date-of-injury checkpoint role.
The lifting line uses pound ranges: up to 10, 11–20, 21–35, 36–50, 51–75, and 76–100. The consequence of a vague entry like “light duty” is rejection because OWCP needs numbers to compare against the Position Description. A misconception is that “no heavy lifting” satisfies the form; OWCP wants a specific pound limit.
Section 4: Environmental and Cardiopulmonary Triggers
OWCP-5b includes specific lines for exposure to dust, fumes, temperature extremes, humidity, and stress. For pulmonary patients, fumes and dust are critical; for cardiac patients, stress and temperature matter most. The consequence of skipping these lines is that the employer may offer a job with the very triggers that caused the injury. A real-world example: a USPS letter carrier with reactive airways disease is restricted from outdoor walking in cold weather below 40°F, which makes a winter route unsuitable.
A common misconception is that “stress” is too vague to enforce. Under ECAB precedent, including Maggie L. Moore, 42 ECAB 484, measurable workplace stressors like deadline-driven work or confrontational customer contact are valid restrictions when tied to documented angina or arrhythmia.
Section 5: Duration and Permanency
The physician must mark whether restrictions are temporary or permanent and, if temporary, give an expected end date. The consequence of “permanent” is that the case moves toward LWEC or schedule award under 5 U.S.C. § 8107 (though 8107 schedule awards do not cover heart or lung organs, impairment ratings still matter for settlement). The example: Dr. Patel marks restrictions permanent for a firefighter with end-stage COPD, triggering vocational rehabilitation under 20 C.F.R. § 10.518.
A misconception is that “permanent” closes the case. In reality, the employee can still work in a modified job and earn wages, and OWCP will compute LWEC using the Shadrick formula from Albert C. Shadrick, 5 ECAB 376.
Section 6: Physician Certification and Signature
The form must be signed and dated by the physician, with the printed name, license number, specialty, and contact information. The consequence of a stamped signature or a signature by office staff is rejection under 20 C.F.R. § 10.331. A real example: a cardiology office uses a rubber-stamp signature on a 5b, and OWCP returns the form with a request for a wet or verified electronic signature. A common misconception is that a fax of a stamped form will pass; it will not.
Three Realistic Scenarios With Outcomes
The next three tables show how small choices on OWCP-5b drive big results.
Scenario A: USPS Letter Carrier With COPD
| Form Entry | Resulting OWCP Action |
|---|---|
| Doctor checks “no exposure to cold below 40°F” | Winter route deemed unsuitable, employee stays on wage loss |
| Doctor checks “8 hours walking” | Claims examiner treats employee as able to walk full route |
| Doctor leaves “fumes” line blank | Employer offers vehicle-exhaust-heavy dock job, employee forced to refuse |
| Doctor marks restrictions permanent | Vocational rehabilitation referral under 20 C.F.R. § 10.518 |
Scenario B: TSA Officer Post-Bypass Surgery
| Form Entry | Resulting OWCP Action |
|---|---|
| Lifting capped at 10 lbs | Checkpoint bag-handling job ruled unsuitable |
| Stress tolerance “0 hours” | Confrontational passenger contact role excluded |
| Standing limited to 4 hours | Modified seated screening role offered |
| EF of 35% attached as objective finding | Restrictions accepted as rationalized |
Scenario C: VA Nurse With Congestive Heart Failure
| Form Entry | Resulting OWCP Action |
|---|---|
| 6–8 hours sitting allowed | Telehealth nursing role offered as suitable |
| No lifting over 20 lbs | Bedside patient transfer duties excluded |
| Temperature extremes restricted | Outdoor clinic assignments excluded |
| Permanent restrictions marked | LWEC determination initiated using Shadrick formula |
Three Named Examples Showing the Form Done Right
Real names make abstract rules concrete.
Example 1: Maria, VA Registered Nurse
Maria suffers a heart attack lifting a patient at a Department of Veterans Affairs hospital. Her cardiologist completes OWCP-5b with EF of 30%, restricts lifting to 10 pounds, and limits standing to 4 hours. The VA offers a telehealth triage role within those limits, and Maria accepts. Her wage loss continues at the difference between her old and new pay under the Shadrick formula.
Example 2: James, TSA Officer
James undergoes a triple bypass after an on-duty cardiac event at Reagan National Airport. His doctor completes a precise 5b restricting stress and lifting. TSA cannot accommodate, and James enters vocational rehabilitation. He retrains as a cybersecurity analyst, and OWCP pays the difference in earnings.
Example 3: Carlos, USPS Letter Carrier
Carlos develops occupational asthma from diesel exhaust on his route. His pulmonologist completes OWCP-5b with FEV1 at 58% predicted and bans exposure to fumes and cold. The U.S. Postal Service offers an indoor sorting job that meets the limits, and Carlos returns to work with no wage loss.
Mistakes to Avoid
The most expensive errors on OWCP-5b are usually small and avoidable.
- Leaving the “objective findings” section blank, which causes a “not rationalized” rejection under 20 C.F.R. § 10.330
- Using vague language like “light duty” instead of pound and hour numbers, which forces the examiner to guess
- Listing conditions OWCP did not accept, which can be read as off-claim and ignored
- Allowing a PA or NP to sign as the attending physician, which violates 5 U.S.C. § 8101(2)
- Using a stamped signature, which fails the certification rule in 20 C.F.R. § 10.331
- Skipping the environmental triggers section, which lets the agency offer a job with the original hazard
- Marking “8 hours” for every activity on a serious cardiac patient, which signals full recovery and ends benefits
- Failing to upload the form through ECOMP, which can delay receipt by weeks
- Not attaching supporting test results like echocardiograms, PFTs, or stress tests
- Confusing OWCP-5b with OWCP-5c, which causes the form to be returned and the file to stall
Do’s and Don’ts for OWCP-5b
Following the do’s and don’ts keeps the claim moving.
- Do attach the most recent objective tests, because OWCP weighs current data more heavily
- Do match accepted-condition wording exactly, because mismatched terms read as off-claim
- Do specify pound and hour limits, because numbers compare cleanly to the position description
- Do submit through ECOMP, because tracked uploads create a date-stamped record
- Do request a copy from the doctor, because the employee needs it for any OWCP-5 appeal
- Don’t sign as a PA or NP, because the form will be rejected
- Don’t use stamped signatures, because OWCP requires a verified signature
- Don’t leave environmental sections blank, because the agency may offer a hazardous job
- Don’t write “permanent” without objective support, because the examiner can override it
- Don’t forget the OWCP file number, because the form may be filed under the wrong claimant
Pros and Cons of a Detailed OWCP-5b
A thorough form helps in some ways and hurts in others.
- Pro: Clear restrictions protect the employee from unsuitable job offers under 5 U.S.C. § 8106(c)
- Pro: Strong objective findings support schedule award and impairment claims later
- Pro: Specific numbers speed up the LWEC determination
- Pro: A complete form reduces second-opinion exam requests
- Pro: Detailed forms support OPM disability retirement applications
- Con: Permanent restrictions can trigger removal proceedings under 5 C.F.R. § 339
- Con: A very detailed form invites second-opinion challenges
- Con: Harsh restrictions can end the federal career path entirely
- Con: Permanent total disability findings can affect Social Security offsets under 42 U.S.C. § 424a
- Con: Detailed forms may be used by the agency to push early retirement
Key Entities You Will Encounter
The OWCP-5b ecosystem includes several important players. The Office of Workers’ Compensation Programs administers the form. The Division of Federal Employees’, Longshore and Harbor Workers’ Compensation handles FECA cases. The Employees’ Compensation Appeals Board reviews disputes. The Office of Personnel Management handles federal disability retirement that often runs parallel. The employing agency, whether USPS, TSA, or VA, makes the job offer based on the form.
The treating physician, the second opinion physician, and the referee physician each play distinct roles. The claims examiner reads the form and applies it to the position description. Vocational rehabilitation counselors use it to plan retraining. A FECA-credentialed attorney can help interpret unclear restrictions.
Recap of Key ECAB Rulings
Several Employees’ Compensation Appeals Board decisions shape how OWCP reads the 5b. Albert C. Shadrick, 5 ECAB 376 created the formula for computing LWEC based on the form’s restrictions. Carl Epstein, 38 ECAB 539 gave special weight to referee opinions when the form conflicts with the treating physician. Maggie L. Moore, 42 ECAB 484 confirmed that measurable stress is a valid restriction. John W. Montoya, 54 ECAB 306 requires objective findings to back every restriction.
These rulings are not just trivia. They are the lens through which the claims examiner reads each checked box. A 5b that ignores them invites denial, while one that mirrors them moves smoothly through the system.
Process for Submitting and Updating the Form
The employee or doctor uploads the completed OWCP-5b through ECOMP, the official electronic case management system. Mailing is allowed but slower; the address is the appropriate district office. The consequence of mailing without tracking is no proof of delivery. A real example: Carlos’s pulmonologist uploads the 5b through ECOMP, and the claims examiner sees it within 48 hours.
Updates are required when the medical condition changes materially. Under 20 C.F.R. § 10.506, OWCP can request updated work capacity evidence at reasonable intervals, often every six to twelve months. The consequence of refusing an update request is suspension under 20 C.F.R. § 10.323. A common misconception is that one form is good forever; it is not.
State-Level Nuances
OWCP-5b is a federal form under federal law, so 20 C.F.R. Part 10 controls regardless of where the employee lives. State workers’ compensation rules do not override OWCP. However, when the federal employee also pursues OPM disability retirement or Social Security Disability, state-licensed physicians complete the OWCP-5b under their state license, and licensure issues can complicate cross-state telemedicine.
For example, a Florida-based VA nurse seen by a Georgia cardiologist via telehealth needs the cardiologist licensed in Florida for the 5b to be valid for the Florida-based federal job. The consequence of a licensure mismatch is rejection. A misconception is that the federal nature of the form overrides state medical licensure rules; it does not.
FAQs
Is OWCP-5b mandatory?
Yes. When OWCP requests it under 20 C.F.R. § 10.506, the employee must obtain and submit a completed form, or compensation can be suspended.
Can a nurse practitioner sign OWCP-5b?
No. Under 5 U.S.C. § 8101(2), only qualifying physicians may sign as the attending provider for cardiopulmonary cases.
Does OWCP pay the doctor to complete the form?
Yes. OWCP reimburses the physician at the OWCP medical fee schedule rate for the time spent completing the form.
Will marking restrictions “permanent” end my federal job?
No. Permanent restrictions can trigger reassignment or vocational rehabilitation, but they do not automatically end employment without 5 C.F.R. § 339 procedures.
Can I appeal a job offer that ignores my 5b restrictions?
Yes. The employee can refuse and request reconsideration, then appeal to the Employees’ Compensation Appeals Board within 180 days.
Is OWCP-5b the same as a schedule award form?
No. Schedule awards under 5 U.S.C. § 8107 use impairment ratings, often on a separate report; OWCP-5b focuses on work capacity.
Do I need a lawyer to complete OWCP-5b?
No. The doctor completes the form, but a FECA-credentialed attorney can help review it before submission for accuracy and consistency with the accepted conditions.
Can OWCP override my doctor’s 5b?
Yes. OWCP can order a second opinion under 20 C.F.R. § 10.320 and, if conflicts exist, a referee exam under 5 U.S.C. § 8123(a).
Will an 8-hour-everywhere 5b end my benefits?
Yes. Marking full capacity on every line tells the examiner the employee is fully recovered, which usually leads to termination of wage-loss compensation.
Can the employer see my OWCP-5b?
Yes. The employing agency receives the restrictions section to make a job offer, but full medical narratives are limited under Privacy Act protections.
Does OWCP-5b apply to Longshore claims?
Yes. Longshore adjudicators under the Division of Longshore and Harbor Workers’ Compensation often accept the 5b for cardiopulmonary work capacity evidence.
How often must OWCP-5b be updated?
Yes, regularly. Under 20 C.F.R. § 10.506, OWCP can request updates at reasonable intervals, typically every six to twelve months for active claims.
