If the date of your injury is on or after December 23, 1991, and if you are totally disabled, the insurer must pay you weekly compensation which equals sixty (60) percent of your average weekly wage, so long as that figure does not exceed the maximum amount payable. The weekly maximum is equal to the average weekly wage in the Commonwealth as determined on October 1 of each year by the director of the Department of Employment Security. The weekly maximum has increased steadily each year and is currently in excess of $600.00 per week. For injury dates prior to December 23, 1991, your rate is 66 and 2/3 percent of your average weekly wage, subject to the same maximum.
