Permanent Partial Disability (PPD) is a Minnesota workers’ compensation benefit that is payable for the permanent functional loss of use of a body part due to a work-related injury. Once you have reached Maximum Medical Improvement (MMI), if you have a permanent injury, your doctor may assign you a permanent partial disability rating. Your doctor will refer to the Permanent Partial Disability guidelines developed by the Department of Labor and Industry, under Chapter 5223 of the Administrative Rules. The percentage rating you are assigned is then multiplied by a dollar figure set by the Minnesota legislature to determine the amount of your permanent partial disability benefit. For example, if you’ve sustained a herniated disc in your lumbar spine, and you’ve been assigned a 10% permanent partial disability rating, the benefit owed to you would be $8,000.00.
