Thank you for this thoughtful reply. I definitely think this is helpful information, however as i previously stated in my OP and replies,

"I've asked my PCP, the specialist, my insurance, the hospital and the doctor performing my procedure if they could refer me to a (chaperone) service. They all confirmed they do not know of any such service...They can recommend transportation, but not a chaperone who will sign your liability release forms."

Medical chaperone is a completely separate complication than transportation. It is required by law when going under anesthesia. I have gone through this twice this year. I was not permitted to check in, much less have the procedure, until my chaperone showed up.

Thank you for taking the time to respond and listing these resources though!
