Major laceration of right vertebral artery, subs encntr

This code signifies a significant tear or cut in the right vertebral artery, a major blood vessel supplying the brain, occurring during a subsequent encounter for care. This injury typically results from trauma to the neck and can lead to severe neurological deficits or hemorrhage. The "subsequent encounter" indicates ongoing treatment or follow-up for the initial injury.

Apply this code when a patient presents for follow-up care, rehabilitation, or management of complications related to a previously diagnosed major laceration of the right vertebral artery. Documentation should clearly state the laterality (right), the severity of the injury (major laceration), and indicate that this is not the initial presentation for the injury.

• Ensure documentation specifies "major laceration" versus a minor laceration or other type of injury to the vertebral artery.
• Verify the encounter type; the "D" seventh character is specific to subsequent encounters.
• Always code the underlying cause of the trauma (e.g., assault, motor vehicle accident) as an external cause code.
