Surgery for a simple intracranial aneurysm, intracranial approach, and carotid circulation is reported using which code?

The appropriate code for surgery for a simple intracranial aneurysm with an intracranial approach related to the carotid circulation is 61700. This code is specifically designated for the intracranial endovascular repair of an aneurysm, which aligns with the surgical intervention being performed in this scenario.

The code captures the complexity and the specific technique used for treating such aneurysms, indicating that the procedure involves accessing the cerebral vasculature through an intracranial method. This is crucial, as coding for specific techniques helps ensure that healthcare providers are accurately reimbursed for the services rendered and that comprehensive records are maintained for patient care.

In contrast, other codes provided in the options refer to different types of procedures, such as those related to other areas of the brain or neck, which do not fit the criteria outlined in the question. The specificity of the code is essential for proper documentation, billing, and healthcare analytics.
