Unsp inj intrns musc/fasc/tend unsp fngr at wrs/hnd lv, init

This code signifies an injury to the intrinsic muscles, fascia, or tendons within an unspecified finger, occurring at the wrist or hand level. The exact nature of the injury (e.g., sprain, strain, tear) is not documented, and the specific finger involved is also unknown. This code is used for the initial treatment of such an injury.

This code is appropriate when a patient presents with a finger injury involving the intrinsic structures of the hand or wrist, but the physician's documentation lacks specificity regarding the exact muscle, tendon, or fascia affected, or the precise finger involved. It is also used when the type of injury (e.g., partial tear vs. complete rupture) is not yet determined or specified in the medical record.

• Only use this code for the initial encounter of the injury. Subsequent encounters will require a different seventh character.
• Avoid this code if the documentation specifies the exact finger (e.g., index, middle) or the specific intrinsic muscle, tendon, or fascia injured.
• If the type of injury (e.g., sprain, strain, tear) is known, a more specific code should be selected.
