Inj flexor musc/fasc/tend l idx fngr at wrs/hnd lv, init

This code signifies an injury to any flexor muscle, fascia, or tendon of the left index finger, specifically occurring at the level of the wrist or hand. This includes sprains, strains, or other unspecified trauma to these structures, excluding complete tears or lacerations. The "initial encounter" designation indicates that the patient is receiving active treatment for this new injury.

Use this code for a patient presenting with pain, swelling, or limited range of motion in their left index finger, where diagnostic imaging or clinical examination confirms an injury to the flexor apparatus at the wrist or hand. This would apply to scenarios such as a strain from repetitive motion, a contusion, or a partial tear of a flexor tendon that is not explicitly classified elsewhere.

• Ensure documentation clearly specifies the left index finger and the injury location as the wrist and hand level.
• Verify that the injury is not a complete tear or laceration, as those have more specific codes.
• Confirm this is the initial encounter for active treatment; subsequent encounters will require a different seventh character.
