Injury of lateral plantar nerve, unsp leg, init encntr

This diagnosis code signifies damage to the lateral plantar nerve, a nerve in the foot that supplies sensation to the sole and motor function to some intrinsic foot muscles. The injury's specific nature (e.g., laceration, contusion, compression) is not documented or known, and the affected leg is not specified.

This code is appropriate for initial encounters when a patient presents with symptoms such as pain, numbness, tingling, or weakness in the lateral sole of the foot, and the clinician suspects an injury to the lateral plantar nerve. It is used when the precise mechanism or type of injury to the nerve is not yet determined or documented.

• Ensure documentation clearly indicates an "initial encounter" for the injury.
• Avoid using this code if the specific type of nerve injury (e.g., transection, contusion) is known and documented; a more specific code would then be appropriate.
• If the affected leg is specified (left or right), a more precise code from the S94.01- or S94.02- series should be used.
