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

This code signifies an injury to one of the small muscles, their surrounding connective tissue, or tendons located entirely within the left little finger, specifically at the wrist and hand level. The exact nature of the injury (e.g., sprain, strain, tear) is not specified.

This code is appropriate when documentation indicates an injury to an intrinsic structure of the left little finger, but the specific type of injury (e.g., sprain, strain, laceration) is not detailed. It is used for the initial encounter for such an injury.

• Ensure the documentation specifies the left little finger and an intrinsic structure.
• Only use this code when the specific type of injury is truly "unspecified." If a more precise diagnosis is available (e.g., sprain, strain), use that code instead.
• The "A" suffix indicates an initial encounter for this injury. Subsequent encounters will require different seventh characters.
