If PERA awards a police officer, firefighter, or deputy sheriff permanent total disability (PTD) benefits then he or she IS still entitled to permanent total disability benefits under Minnesota worker’s compensation. Permanent total disability benefits in workers’ compensation are benefits payable to injured workers who are unable to return to gainful employment. PTD is calculated using an injured worker’s average weekly wage (AWW) and is multiplied by 2/3 for a compensation rate under Minnesota Statute §176.011, subdivision 18. This amount is capped at the same limit as temporary total disability (TTD) and is subject to cost of living adjustments over time. PERA disability benefits and Social Security Disability Income (SSDI) benefits are also increased on a very limited basis over time. In many cases, employees must reach a certain rating of permanent partial disability (PPD) before he or she is awarded PTD benefits or deemed to have reached PTD. These ratings take into account all permanent conditions, work related or not, that affect the employee’s ability to work.
