if you are not released to drive, and your ride , (my husband )got a job out of town leaving me no way to get to physical therapy , is insurance liable to pay for me to get to therapy ,
It's up to your PTP to provide the medical reasoning, and request for transportation to medically necessary appts, get the prior authorization from the CA. Without that... you have other options... bus, taxi, friend, other family member etc. Mileage will be reimbursed, or the CA will arrange for medical transportation.
