CP Angle vs Skull Base Codes

Question:

I just got a case where the neurosurgeon and ENT want to bill the following codes:

ENT, 61596, Transcochlear posterior fossa skull base code for the approach.

Neurosurgeon, 61616, intradural resection of a posterior fossa skull base tumor

Is this correct? The diagnosis is a right translabyrinthine approach to cerebellopontine angle and internal auditory canal with resection of vestibular schwannoma.

Answer:

CP angle tumors, for example vestibular schwannomas, treated via a translabyrinthine approach/exposure have a CPT code that specifically describes the work and value of this approach and resection. That code is61526, Craniectomy, bone flap craniotomy, transtemporal (mastoid) for excision of cerebellopontine angle tumor.The resection is essentially in the posterior fossa however, since it has a code specifically developed and valued for this procedure, code 61526 must be used. It is valued to reflect the work of this complex resection.

Coding for a Chiari Malformation

Question:

Is there a code for a craniotomy for decompression for Chiari? And the surgeon also did a C1 laminectomy.  Is that a separate code?

Answer:

The code for a decompressive craniotomy for Chiari is 61343 and includes the work of the cervical laminectomy.

Lumbar Drain in a Cranial Procedure

Question:

Can placement of a lumber drain be billed separately with a cranial procedure? I heard that placing drains is not billable.

Answer:

You are correct that placement of a drain in the surgical site/exposure is not separately billable. Placing a lumber drain via a separate incision ( in the back) during a cranial procedure is billable as it is in a separate anatomic location.

Report code 62272 if placed without fluoroscopic guidance and 62329 if fluoroscopy is used. The fluoroscopy is not separately billed.

Ruptured Aneurysm and a Hematoma

Question:

The patient present with a ruptured aneurysm. A craniotomy was performed to clip the aneurysm and the hematoma was evacuated to access the aneurysm. Are both the aneurysm clipping and the hematoma evacuation billable?

Answer:

No, the aneurysm codes are valued for ruptured or non- ruptured aneurysms and evacuating the hematoma to access and treat the aneurysm is included in the aneurysm code.
