Unsp injury of blood vessel of left middle finger, init

This diagnosis code signifies an injury to a blood vessel within the left middle finger, where the specific type of vessel damage (e.g., laceration, contusion, rupture) is not documented. It indicates the initial presentation or active treatment phase of such an injury.

This code is appropriate for documenting a patient's first encounter for a left middle finger blood vessel injury when the physician's documentation does not specify the exact nature of the vascular trauma. Examples include a crush injury to the finger with observed bleeding but no detailed vessel identification, or a penetrating wound where vascular involvement is noted but not further characterized.

• Ensure the documentation clearly states "left middle finger" and "blood vessel injury" without further specificity.
• Verify that this is the patient's initial encounter for this specific injury. Subsequent care would require a different encounter character.
• If the specific blood vessel (e.g., artery, vein) or the type of injury (e.g., laceration, puncture) is documented, a more specific code should be selected.
