This code signifies an injury to the intrinsic muscles, fascia, or tendons of a finger other than the thumb, occurring at the wrist or hand level. This includes a range of injuries such as strains, sprains, or tears affecting the delicate structures responsible for fine motor control within the hand. It specifically excludes injuries to the thumb.

Apply this code for patients presenting with acute trauma to the intrinsic musculature, fascia, or tendons of the index, middle, ring, or little finger. This would be appropriate for injuries sustained from activities like sports, falls, or repetitive strain that result in damage to these specific structures. It is used for the initial encounter for such an injury.

• Ensure the injury is to an intrinsic muscle, fascia, or tendon, not a nerve or bone.
• Verify the injury location is to a finger other than the thumb and at the wrist/hand level.
• Confirm this is the patient's initial encounter for this specific injury.
