Formal rating determinations shall be deemed to constitute evidence:

• A. Which is rebuttable under certain circumstances
• B. Only as to the relationship between the disability described and the percentage of permanent disability
• C. Which is not rebuttable
• D. Which is presumed correct

Answer: (B)

The main idea is that a formal rating determination functions as evidence specifically about how the described disability translates into a permanent disability (PD) percentage. It documents the link between what the employee is medically described as able or disabled to do and the numeric PD rating assigned. It does not, by itself, decide other issues such as causation, entitlement beyond the PD amount, or serve as an absolute or all-encompassing verdict. If later evidence suggests a different mapping, that rating can be reconsidered, but its probative value is limited to showing the relationship between the described disability and the PD percentage. This is why the correct choice describes the rating determination as evidence only as to that relationship.
