Unsp injury of musc/fasc/tend at forarm lv, right arm, init

This code signifies an injury to the muscles, fascia, or tendons in the right forearm that is not further specified as a strain, laceration, or other specific type of trauma. It indicates the initial presentation of such an injury, where the exact nature of the damage to these soft tissues is unknown or undocumented.

This code is appropriate for documenting an initial encounter where a patient presents with pain, swelling, or limited function in the right forearm, and the provider suspects a muscle, fascia, or tendon injury but has not yet determined the specific type or extent of the injury. It is used when the documentation lacks details to assign a more specific code, such as a muscle strain or tendon tear.

• Only use this code for the initial encounter of the injury; subsequent care would use a different seventh character.
• Ensure documentation clearly specifies the right forearm; if left or unspecified, a different code is required.
• Avoid this code if the documentation provides enough detail to assign a more specific injury code (e.g., S56.311A for a strain of muscle(s) and tendon(s) of the right forearm).
