S86.399A
ICD-10-CMOther injury of muscle(s) and tendon(s) of peroneal muscle group at lower leg level, unspecified leg, initial encounter
This code signifies an injury to the peroneal muscles or their tendons in the lower leg, such as a strain, sprain, or partial tear, where the specific nature of the injury is not detailed. It applies when the affected leg is not specified in the documentation. This is an initial encounter for the injury.
Use this code for a patient presenting with an acute, unspecified injury to the peroneal muscle group of the lower leg. This is appropriate when the physician's documentation indicates an injury to this muscle group but does not specify the exact type (e.g., "peroneal strain") or the laterality.
