Unsp inj extn musc/fasc/tend l mid fngr at wrs/hnd lv, init

This code signifies an unspecified injury to the extensor muscle, fascia, or tendon of the left middle finger, occurring at the wrist or hand level. This indicates trauma to the structures responsible for extending the middle finger, without further specification of the exact nature of the injury (e.g., strain, tear, laceration).

Use this code for initial encounters where a patient presents with an injury to the extensor mechanism of their left middle finger, and the specific type of injury (e.g., partial tear, complete rupture) has not yet been determined or documented. This is appropriate when the injury location is clearly at the wrist or hand level, affecting the middle finger's extensor components.

• Ensure documentation specifies the left middle finger and the injury location at the wrist or hand level.
• Avoid using this code if a more specific diagnosis (e.g., laceration, sprain, strain) is documented for the extensor structures.
• Remember the "A" seventh character denotes an initial encounter for active treatment of the injury.
