Can anyone help me to clarify this billing question:

Bilateral knee 2v x rays done for pain on each joint (not comparison).
Are these two significant procedures and how these should be charged?

one line, 7XXXX SI S – MOD 50
OR
two lines 7XXXX with 2 SI S (?) is this possible – mod XU/LT/RT??
OR
one line charge with SI S and cpt for minimum 3 or 4 views (summarizing the total # of views)?
OR other?

Thanks upfront.
