Thoracoscopic surgical procedure converted to open procedure

This code indicates that a planned thoracoscopic surgical procedure was initiated but could not be completed minimally invasively and required conversion to an open surgical approach. This signifies a change in surgical technique during the operation due to unforeseen circumstances or complications.

This code is used when documentation clearly states that a thoracoscopic procedure, such as a VATS lobectomy or wedge resection, was attempted but subsequently converted to an open thoracotomy. It applies regardless of the reason for conversion, which could include extensive adhesions, uncontrolled bleeding, or difficulty visualizing anatomy.

• Always ensure the operative report explicitly documents the initial thoracoscopic attempt and the subsequent conversion to an open procedure.
• This code is a primary diagnosis and should be sequenced first when the conversion is the reason for the encounter.
• Do not use this code if the procedure was planned as an open procedure from the outset, even if a scope was used for initial visualization.
