Coding Twist Drill Ventriculostomy with Craniotomy/Craniectomy

Question:

When is it ok to unbundle 61107 from the craniotomy/craniectomy code?

Answer:

It is acceptable to report both codes when the ventriculostomy placed via twist drill hole is performed through a completely separate approach/access point from the craniotomy/craniectomy.  For example, you’ve performed a right suboccipital craniectomy and place a left frontal twist drill hole for placement of a ventricular catheter.
