MEDIHELP DOES NOT HELP AT ALL

So my grandmother needs to have a G&C procedure done. She has multiple chronic conditions and oncology baskets active. She visited her specialists who app**** for the procedures authorization just to find out that there is 35% co payment for non network day procedure ****. Ironically the hospital and the Dr is on the network strange enough there is no day procedure network where the Dr can practice to have this co payment removed. Now my question arises a 75 year old frail patient paying extra in premiums to use any network and having being treated for years at the same hospital and the same team of DR's must now set search for a new team of Dr's bring them up to speed on her medical history while her condition deteriorates. I just do not se the logic in this. Also why is the list of network day procedures not shared in the beginning of the year with the member how must a 75 year old log on to a member zone ? Really this is such a slap in the face...
