Wiki 20551 multiple units

[btauzin]

My doctor is wanting to bill 20551 with a 50 modifier and 3 units - I was always told when billing a 50 mod that we use 1 unit only.
Did rules change that I am unaware about????

See attached information from AAPC Coder regarding modifier 50. I hope this helps.
