What influences the rating of permanent partial disability?

The rating of permanent partial disability is influenced primarily by the extent of impairment and medical evaluation. This is because the assessment focuses on the degree to which the injury affects the worker's ability to function in their daily life and work. Medical evaluations, such as those performed by qualified healthcare providers, help determine the specific nature of the impairment, which is critical in assigning a proper disability rating.

The thoroughness of the medical evaluation ensures that all factors associated with the impairment are taken into consideration, including the physical limitations imposed by the injury and how it may affect the worker's capacity to perform certain tasks. The rating is thus formulated to reflect both the clinical findings and the impact of these findings on the individual’s functional abilities.

While other factors mentioned in the choices may have some influence in different contexts, they do not directly determine the rating of permanent partial disability in the same way that the extent of impairment and medical evaluation do. The age and previous employment of the worker might provide context for their overall situation but are not the primary determinants for the disability rating itself. Similarly, the cost of treatment and recovery time could be factors in a broader discussion about a case, but they do not directly influence the rating. The employer's responsibility and claims history may come into play
