Unspecified injury of muscle and tendon of head, init encntr

This code signifies an injury to the muscles or tendons within the head region, where the specific nature of the injury (e.g., strain, tear, laceration) is not documented. It indicates that the patient is receiving initial active treatment for this unspecified head muscle/tendon injury.

Use this code when documentation clearly states an injury to a head muscle or tendon but lacks specificity regarding the type of injury. This is appropriate for the initial encounter when the patient first presents for treatment of the acute injury. Supporting documentation would include physician notes detailing a head injury with involvement of muscle/tendon, without further diagnostic clarity.

• Avoid using this code if a more specific injury (e.g., S09.11XA for muscle strain) is documented.
• Ensure the "A" for initial encounter is appropriate; subsequent care would require different seventh characters.
• Always query the provider for greater specificity if possible to allow for more precise coding.
