Impairment Rating and Head Injury

A head injury, particularly one that results in a traumatic brain injury (TBI), can have life-altering consequences. It’s not just the immediate physical repercussions but also the potential for long-term or permanent disabilities that necessitate a robust understanding of impairment ratings. Impairment ratings determine the degree of permanent disabling effects after injury, which is critical in personal injury claims, especially in guiding the level of compensation claimants may receive.

What Is an Impairment Rating, and Why Does It Matter?

An impairment rating is an essential aspect of a personal injury claim. It quantifies the level of physical or mental injury a claimant has sustained, which is fundamental to determining the compensation they may receive. In the case of head injuries, which often lead to permanence or long-term impairments, a detailed and accurate impairment rating is a non-negotiable tool in the fight for justifiable outcomes.

The rating takes into account various factors, including medical history, current symptoms, and prognosis for recovery. For claimants with head injuries, particularly TBI, the implications are significant, as they may affect the ability to work, the need for ongoing medical care, and the overall quality of life.

Determining the Degree of a Permanent Disability in an Impairment Rating

An important early step in the impairment rating process is to establish the claimant’s Maximum Medical Improvement (MMI). MMI represents the point where a claimant’s condition has stabilized, and further treatment is unlikely to enhance their medical status. Only then can a certified doctor provide an impairment rating, a process that can significantly affect the ultimate settlement of a personal injury claim.

How Is an Impairment Rating Determined?

To determine an impairment rating, the evaluating physician compares the claimant’s condition against established medical guidelines. For head injuries, the relevant reference is often the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment, which provides a standardized approach to computing impairment ratings.

The evaluation involves assessing various descriptors and functional limitations due to the head injury. The severity of cognitive, behavioral, and physical deficits contributes to the final impairment rating. This holistic approach ensures that all facets of a head injury’s impact on a claimant are considered.

What exactly is MMI?

The concept of MMI is critical; it signifies the end of active medical care and the point at which the physician can confidently assess the permanency of the claimant’s impairments. With head injuries, this determination can be more nuanced, as symptoms such as memory loss, altered mental states, and personality changes might delay the declaration of MMI.

How long does it take for a doctor to declare you to be at MMI?

The length of time it takes to reach MMI varies based on the severity of the head injury and the individual’s response to treatment. Mild TBI, for instance, might reach MMI within a few weeks, while severe TBI cases could take years. Early estimations play a role, but an accurate declaration of MMI considers sustained functional improvements over time.

Types of Disability Category

When it comes to head injuries, disability categories serve as a framework to assess different aspects of a claimant’s life that have been affected. These categories guide the physician in arriving at an overall impairment rating:

Physical Impairment

Physical impairments stemming from head injuries can include motor skill deficits, sensory processing issues, or even total loss of certain physical abilities. An impairment rating in this category reflects the limitations in the claimant’s ability to perform typical daily activities.

Cognitive Impairment

Cognitive impairments such as memory loss, difficulty concentrating, and slower processing speeds are common in TBI cases. The impact on cognitive functioning directly affects one’s employability, personal independence, and overall quality of life, and is calculated within the impairment rating.

Psychiatric Impairment

Psychiatric or behavioral changes often accompany head injuries, introducing new challenges to a claimant’s personal and professional life. These can be as debilitating as physical or cognitive deficits and contribute to the overall impairment assessment.

How To Calculate An Impairment Rating For A Traumatic Brain Injury

An impairment rating calculation for TBI is a highly detailed process that must take into account a range of functional limitations. Examining each component thoroughly ensures that the rating accurately reflects the impact of the injury.

What Are The Components Of An Impairment Rating For A Traumatic Brain Injury?

For an impairment rating related to TBI, specific components must be considered, as outlined in Chapter 4 of the AMA Guides:

  • Neuropsychological Evaluations: These are vital for assessing cognitive and emotional deficits resulting from TBI. They provide a structured approach to identifying impairments that may not be apparent through physical examinations.
  • Functional Deficits: The physician must look at the impairments in performing activities of daily living. Restrictions or limitations here directly affect the impairment rating.
  • Central Nervous System Section: Here, the impact on daily functions—such as sleep, cognition, speech, and behavior—is rated using defined tables and criteria within the AMA Guides.

Examples Of How Certain Impairments Are Graded

For instance, an individual who requires supervision and direction for daily activities may fall within a 15-29% impairment range. If the level of support necessary increases, so does the impairment rating, with those requiring continued supervision and home confinement rated between 30-49%.

Another crucial aspect is to avoid premature rating, as TBI recoveries can be protracted. Patient-specific improvement timelines must be considered to prevent inflated ratings that do not reflect a true MMI status.

Legal Considerations in Impairment Ratings for Head Injuries

Navigating the legal aspects of impairment ratings in personal injury claims is as important as the medical evaluation. When disputing an initial rating, claimants must be prepared to present evidence supporting a higher impairment level.

Proving a Diagnosis of TBI Is Crucial

To establish the basis for a TBI-related impairment, thorough documentation and specialized testing are essential. Claimants should work closely with their legal counsel to ensure all necessary medical evidence is compiled and presented effectively.

Access to Rehabilitation Programs

The rating process must account for any ongoing or potential rehabilitation programs, as these could significantly impact the ultimate impairment level. Access to evidence-based treatment should be factored in, with the goal of maximizing recovery and minimizing permanent impairment.

An impairment rating is not just a number—it’s a reflection of a claimant’s life-altering experiences. For head injury claimants, understanding how these ratings are calculated and being an active participant in the evaluation process is crucial to securing a fair outcome.

With the guidance provided here, personal injury claimants can approach the impairment rating process with confidence and ensure that their voices are heard and their rights are protected. Impairment ratings for head injuries are complex, but with the right information and advocacy, claimants can successfully negotiate the personal injury claim process and receive the support they need to move forward with their lives.
