medical mutual coverage??

hi friends...i am just starting on this journey.  i am reading book, have a seminar set up and a dr. appt for august...one of my main concerns is how much this will cost.  i have medical mutual supermed and it is pretty good but i am worried about out-of-pocket expense....anyone got any info for me?  thanks!!  i will be going through st. vincent charity hospital or cleveland clinic.  looking forward to hearing from you!
