Is it true that you are entitled to certain insurance benefits from your own insurer, regardless of who was at fault? It’s true, in Canada these benefits are often called ‘Section B benefits’. However, insurers like to erroneously inform injured clients that they will only ‘authorize’ 21 treatments (of various kinds). This is not true.
The reality you are entitled to get treatments deemed medically essential so long as the treating physician deems them necessary. Your insurance company has to reimburse you for the cost of those treatments. There are limitations on certain kinds of treatment, but it’s certainly not capped at 21.
