especially when some doc tries to bill both you and your insurance for the seventeenth time on that one quirky test that's already been paid for... Soo much of it all is tied to the 'date of service' and all those bills go thru separate corporate entities with names never heard of.....
I keep a calendar, keep all the appt cards and a Word 'calendar' [for each year] in which I note what tests were done and make sure I keep copies of any doc orders I can get my hands on....That way I have a whole slew of paper and notes that 2 months or 4 years down the road, well I can find out what I actually did or got done to and for what.

At the bottom of the calendar...I make extra notes about making appts in the future...as some offices seem incapable of actually MAKING appts for 4-6 months in advance. So I've notes 'call in july for sept appt w/doc X' kind of things...That way you can make your appts in time to get appt times that are more convenient for YOU..

With this kind of stuff - you can never have enuf good notes!
's and keep heart, strength, faith and hope always - j
