Unsp inj extensor musc/fasc/tend finger at wrs/hnd lv, init

This code signifies an unspecified injury to the extensor muscle, fascia, or tendon of any finger other than the thumb (i.e., index, middle, ring, or little finger) at the wrist or hand level. The nature of the injury (e.g., strain, tear, rupture) is not specified.

This code is appropriate for initial encounters when a patient presents with an acute injury to the extensor mechanism of a non-thumb finger in the hand or wrist region, and the specific type of injury (e.g., laceration, sprain, rupture) has not yet been determined or documented. It is used when the physician's documentation indicates an injury to these structures but lacks further detail.

• Ensure the documentation clearly specifies "other finger" (not the thumb) and the injury location at the "wrist and hand level."
• Only use this code for the initial encounter for the injury. Subsequent care would use a different seventh character.
• Avoid using this code if a more specific injury (e.g., laceration, sprain, rupture) or a specific extensor tendon (e.g., extensor digitorum) is documented.
