Because it lacks an earnings test, the VASRD
stands in sharp contrast to SSDI, where earning over a certain amount ceases payment after a trial work period, and SSI, where each dollar of earnings (above a small threshold) reduces benefits by 50 cents.
The disability costs are based on the prevalence of the most probable VASRD
associated with the queried ICD-9 diagnosis among the Army veteran population.
Section 1642 of the National Defense Authorization Act 081 states that the service secretaries shall, to the extent feasible, only use the criteria in the VASRD
to rate compensable disabilities, including any applicable interpretations by the United States Court of Appeals for Veterans Claims.
