ICP Monitor and EVD Placed on Both Sides

Question:

We placed an ICP monitor on the left side of the cranium and a right ventriculostomy, both using the twist drill. We know to use CPT 61107 but wondered about using modifier 50 (bilateral procedure). Thoughts?

Answer:

Medicare does not recognize modifier 50 on 61107, though some payors might or may even recognize using HCPCS II modifiers RT (right) and LT (left). We suggest you report 61107 and 61107-59 (or modifier XS) just to be clear that the same CPT code was performed on either side of the head.
