Cereb infrc due to unsp occls or stenosis of unsp verteb art

This code signifies a stroke resulting from a blockage or narrowing within a vertebral artery, where the specific nature of the occlusion/stenosis and the affected vertebral artery (left or right) are not documented. It indicates ischemic damage to brain tissue caused by insufficient blood flow through this critical vessel.

Use this code when documentation confirms a cerebral infarction attributed to vertebral artery disease, but the physician has not specified the type of occlusion (e.g., thrombosis, embolism) or the laterality of the affected artery. This is appropriate when the clinical picture points to a vertebral artery origin for the stroke, but further detail is lacking.

• Ensure the documentation explicitly states "cerebral infarction" and implicates a vertebral artery.
• Avoid using this code if the laterality (left/right) or the specific type of occlusion/stenosis is clearly documented; instead, select a more specific code.
• Always review the entire medical record for additional details that might allow for a more precise code selection.
