The surgeon performing the procedure can bill 61781 OR 61782 - NOT both codes.
From the CPT Assistant, July 2011 Page: 12-13 Category: Stereotactic Computer-Assisted (Navigational) Procedures"
Code 61782 is reported for stereotactic computer-assisted (navigational) procedures for the cranial, extradural region. It is reported in addition to the primary procedure code, either open or endoscopic. A parenthetical note indicates that codes 61781 and 61782 should not be reported by the same provider during the same surgical session.
Question:
When are codes 61781, 61782, and 61783 reported?
Answer:
Code 61781 is reported when stereotactic computer-assisted navigation is used with primary procedures that are performed in the cranial, intradural region. Code 61782 is reported when performed in conjunction with otolaryngologic/head, and neck (craniofacial) procedures, including functional endoscopic sinus surgeries (FESS) and skull base resection codes. Examples include the procedures described by codes 31254-31256, 31267, 31276, 31287, 31288, 31290-31294, and 61548. Code 61783 is reported with primary procedures performed in the spinal region such as the placement of fixation devices requiring precision (eg, C1-C2 screws) or a complex tumor resection.
Question:
Who reports stereotactic computer-assisted (navigational) procedures?
Answer:
Neurosurgeons, otolaryngologists, orthopedists, and spine surgeons report codes 61781, 61782, and 61783 when this type of navigation is needed for the procedure and the patient.
Question:
How many units of code 61782 may be reported during a single operative session involving multiple endoscopic sinus procedures?
Answer:
CPT code 61782 is reported once per surgical session, regardless of the number of sinuses involved. The code includes planning, setup of the instrument, and its intraoperative use. CPT codes 61783 and 61784 are also reported only once per surgical session.
