Modifier for Bilateral Catheterization

Question:

Do you code bilateral catheterization codes with modifier 50? 

Answer:

Catheterization codes below the diaphragm can be coded with bilateral modifier 50, however, catheterization codes above the diaphragm should be coded with modifier 59 on the second code. (ex. Lower extremity 36245-50, upper extremity 36215, 36215-59).
