Laceration of blood vessel of unspecified thumb, init encntr

This code signifies a cut or tear to a blood vessel within an unspecified thumb. This injury is acute and represents the initial treatment for the laceration. It does not specify whether the laceration is to an artery, vein, or capillary.

Use this code for patients presenting with an acute laceration affecting a blood vessel in the thumb, where the specific thumb (right or left) is not documented. This code is appropriate for the initial encounter for treatment, such as wound exploration, repair, or initial assessment in the emergency department.

• Ensure documentation clearly states "unspecified thumb" if laterality is not provided.
• Confirm this is the patient's initial encounter for this specific injury. Subsequent encounters will require a different seventh character.
• Look for additional codes to describe the depth of the laceration, associated nerve damage, or foreign body, if present.
