physicals/preventive visits

does anyone have an easy way to bill for medicare physicals and other payer physicals. or a cheat sheet they use. what can be included, etc ?
I have problems with G0102 and 82270 for men. what needs to be billed with a modifer. The more articles I read the more confusing it gets.

Google "Medicare Preventive services Quick Reference Information" and you will get the 2 pdf's from CMS that explain it all.
