"Inspection in all directions and mobilization of this vessel further distally revealed that there was no frank aneurysm. There was an aneurysmal dilation of an area of approximately 2 mm in the proximal portion. This was not clippable and was not a true aneurysm. ... Muslin gauze in three strips was used to wrap the area circumferentially."
How should I report this?

Answer: As described, there is no precise code for this procedure. Because the surgeon clipped a middle cerebral artery aneurysm -- and then discovered and inspected the dilation upon further exploration of a branch of the same artery -- report 61700 (surgery of simple intracranial aneurysm, intracranial approach; carotid circulation) with modifier -22 (unusual procedural services) appended to account for the additional time and effort required to wrap the artery. When appending modifier -22, include documentation to justify the request for additional payment.
