Unspecified injury of left vertebral artery, subs encntr

This code signifies an injury to the left vertebral artery where the specific nature of the injury (e.g., laceration, contusion, dissection) is not documented. This particular instance refers to a patient receiving follow-up care for such an injury.

Apply this code for subsequent encounters when a patient presents for ongoing management, healing, or complications related to a previously diagnosed, but unspecified, injury of the left vertebral artery. Documentation should clearly indicate the encounter is not for initial treatment and that the specific type of arterial injury remains undefined.

• Ensure "D" for subsequent encounter is appropriate; "A" (initial) or "S" (sequela) would be used for different encounter types.
• Avoid using this code if the specific type of vertebral artery injury (e.g., S15.112- for laceration) is documented.
• Always review the medical record for laterality (left vs. right) and the specific vertebral artery involved.
