Wiki Reference guide for colon resection

[pacificcoder]

I do alot of colon resection and i'm new to this section of sx. Is there a good reference book anyone knows that will be helpful. I get confused with those anastamosis part. I looked at ama website but the description on the book is similar to encoderpro same goes for tci and supercoder.

Anybody using any kind of reference book that explains the cpt codes better?

Thanks
