The Nevada Permanent Partial Disability Award Calculation Work Sheet For Disability Over 25 Percent Body Basis (PPD) is a document used by the Nevada Division of Industrial Relations to calculate the permanent partial disability award for an injured worker. The work sheet calculates the award based on the criteria of disability, body parts affected, percentage of disability, and other factors. There are two types of Nevada Permanent Partial Disability Award Calculation Work Sheet For Disability Over 25 Percent Body Basis: the Standard PPD Work Sheet and the Modified PPD Work Sheet. The Standard PPD Work Sheet is used to calculate the award for disabilities that affect the entire body and the Modified PPD Work Sheet is used to calculate the award for disabilities that affect only certain body parts. Both work sheets take into account the injured worker's age, occupation, pre-injury wages, and body part affected. The calculation also takes into consideration the percentage of disability, number of weeks of disability, and any payments made by an insurance carrier. The resulting permanent partial disability award is a lump sum payment that is intended to compensate the injured worker for the long-term effects of the injury.
