The cost of physical therapy after a car accident can vary depending on a number of factors, such as the severity of the injuries sustained and the type of treatment needed. In general, however, physical therapy sessions can cost anywhere from $75 to $150 per session, and many people need several sessions in order to fully recover from their injuries. In some cases, health insurance may cover the cost of physical therapy, but it's important to check with your provider to determine what is covered under your policy. If you don't have health insurance, or if your policy doesn't cover the full cost of physical therapy, you may need to pay for the treatment out of pocket. If you do file a lawsuit against the at-fault driver, the cost of PT may be covered.
