The First OWCP Impairment Rating Isn’t Always the Final Answer

Most federal workers breathe a sigh of relief when they finally receive their OWCP impairment rating. After months or sometimes years of medical treatment, it can feel like the last major step before a schedule award is issued, and it’s understandable to assume the rating is final. But in many cases, it isn’t.

Some federal workers often believe the first impairment rating issued by an OWCP-selected physician represents the final word on their case, but the reality is often more nuanced. Depending on the medical evidence and how the evaluation was conducted, impairment ratings may be clarified or challenged before a final decision is made.

What Is an OWCP Impairment Rating?

OWCP impairment ratings are the measurements of permanent loss of function resulting from an accepted work-related injury. Unlike an initial OWCP claim, which focuses on establishing that an injury occurred during federal employment, an impairment rating focuses on the lasting physical effects of that injury after the anticipated maximum medical improvement has been reached.

The impairment percentage assigned to the injured body part becomes one of the most important factors in determining a worker’s eligibility for a schedule award.

Why Two Doctors Can Reach Different Conclusions

Impairment evaluations involve a degree of professional judgment. Two physicians may review the same medical records, examine the same patient, and still arrive at different impairment percentages. That doesn’t necessarily mean one physician is wrong.

Differences often come down to how each physician interprets the medical findings and applies the AMA Guides to the Evaluation of Permanent Impairment. Factors such as range-of-motion measurements, strength testing, functional assessments, and even the completeness of the supporting medical records can all influence the final rating. When those elements are evaluated differently, or when important information is missing, the resulting impairment percentages can vary considerably.

The First Rating Isn’t Always the End of the Story

Many workers assume the first percentage assigned is automatically final. However, there are situations where additional medical evidence may help clarify or support a different impairment rating. For example:

• New diagnostic testing becomes available.
• Important medical findings were overlooked.
• The physician’s report lacks sufficient explanation.
• Functional limitations were not fully documented.
• The AMA Guides were not applied completely or accurately.

Every situation is different, but the initial rating isn’t always the final answer, which allows workers to make more informed decisions before accepting the outcome.

Why Documentation Still Drives Everything

An impairment evaluation is only as strong as the medical records supporting it. The physician relies heavily on:

• Treatment records/Surgical reports
• Diagnostic imaging
• Physical therapy records
• Prior examinations
• Physician narratives

Incomplete or inconsistent documentation can make it much harder to support the appropriate impairment percentage, which is why we emphasize the importance of strong OWCP medical documentation throughout every stage of the claim.

Your Impairment Rating May Affect Your Schedule Award

For most federal workers, the impairment rating becomes the foundation of a schedule award. A higher or lower impairment percentage may significantly affect the compensation ultimately awarded. That’s why the evaluation deserves careful attention rather than simply assuming the first number issued is the only possible outcome.

Our Team Can Make a Difference

Impairment ratings involve much more than assigning a percentage. Working with an experienced team of federal workers’ compensation lawyers can help ensure your OWCP impairment rating accurately reflects the lasting effects of your injury and supports the compensation available under the law.
