Common Mistakes That Delay Federal Impairment Rating Approvals & How to Avoid Them

Common Mistakes That Delay Federal Impairment Rating Approvals & How to Avoid Them

When you’re navigating the federal workers’ compensation system, your impairment rating is one of the most important steps toward receiving the Schedule Award benefits you deserve. 

But even when an injury is real and well-documented, small mistakes in the impairment rating process can cause unnecessary delays or even lead to denials that require appeals and resubmissions.

Understanding what the Department of Labor (DOL) looks for and how to avoid preventable errors can make the entire process smoother and faster. At Advanced Care Specialists, our federal workers’ compensation providers help patients complete accurate, compliant impairment ratings that stand up to OWCP review. Below are a few of the common mistakes we see from patients we have worked with.

1. Missing or Incomplete Medical Documentation

The most common reason for impairment rating delays is incomplete medical records. OWCP requires:

    • A clear diagnosis
    • Documentation of the accepted conditions
    • Treatment history
    • Objective findings
    • A statement confirming the patient has reached Maximum Medical Improvement (MMI)

When any of these elements are missing or unclear, OWCP cannot process the rating. That often means additional requests for documentation or a complete resubmission.

How to avoid this mistake: Work with a federal doctor who understands OWCP requirements and gathers all necessary medical records before performing the impairment evaluation.

2. Using the Wrong Edition of the AMA Guides

Federal impairment ratings must be performed using the AMA Guides to the Evaluation of Permanent Impairment, Sixth Edition. If a doctor uses the wrong edition or blends editions, which some non-federal providers unknowingly do, the report cannot be used and must be corrected or redone.

How to avoid this mistake: Ensure your evaluation is completed by a provider trained in the AMA 6th Edition and federal impairment rating standards.

3. No Clear Statement of Maximum Medical Improvement (MMI)

OWCP cannot issue a Schedule Award until a patient reaches maximum medical improvement. If the impairment report does not clearly state that the patient is at MMI, the claim will stall.

How to avoid this mistake: The impairment rating report should prominently include an MMI statement supported by clinical evidence and treatment history.

4. Failure to Tie Impairment Directly to Accepted OWCP Conditions

A Schedule Award can only be calculated for accepted conditions under your federal claim. If the report includes impairments related to unaccepted or unrelated diagnoses, OWCP will request clarification, which causes delays.

How to avoid this mistake: Your federal doctor must connect each impairment percentage directly to an accepted condition and exclude unrelated conditions from the calculation.

5. Inaccurate or Missing Objective Measurements

Federal impairment ratings require objective, reproducible data such as:

    • Range of motion measurements
    • Strength testing
    • Neurological findings
    • Diagnostic results

If the documentation is vague, inconsistent, or subjective, OWCP may question the validity of the rating.

How to avoid this mistake: Choose a provider who performs standardized objective measurements and includes clear data tables in the final report.

6. Reports That Do Not Follow OWCP Formatting Expectations

Even when the medical portion is accurate, reports may be delayed because they:

    • Lack a clear narrative
    • Combine sections incorrectly
    • Do not include tables, calculations, and rationale
    • Are missing signatures or credentials

OWCP expects a specific structure, and deviations can cause administrative delays.

How to avoid this mistake: Work with a clinic that regularly performs federal impairment ratings and knows how to format the documentation correctly for DOL review.
