Mech compl of carotid arterial graft (bypass), init encntr

This code signifies a mechanical issue, other than an occlusion or stenosis, affecting a carotid arterial bypass graft. This could include problems like kinking, displacement, or leakage of the graft itself, or a suture line disruption, occurring during the initial treatment period.

Apply this code when a patient presents with a new or acute mechanical complication of a carotid bypass graft, such as a graft aneurysm, pseudoaneurysm, or structural failure. This is appropriate for the initial encounter where the complication is being evaluated and treated.

• Ensure the documentation clearly specifies a mechanical complication, not an infection or inflammatory process.
• Verify that the complication is related to a carotid arterial graft (bypass) and not another type of vascular graft.
• Confirm this is the initial encounter for the specific complication; subsequent encounters would use a different seventh character.
