Strain of muscle and tendon of head, initial encounter

This code signifies a non-traumatic injury to the muscles or tendons of the head, such as those involved in facial movement or scalp tension. It represents an overstretching or tearing of these soft tissues, leading to pain and dysfunction.

Apply this code when documentation indicates a strain of the head's muscles or tendons, often resulting from sudden movements, overuse, or sustained awkward positions. Supporting documentation should clearly specify the head as the anatomical site and confirm the initial treatment for the injury.

• Ensure documentation specifies "strain" and not a contusion or sprain, which are distinct injuries.
• Verify the encounter is indeed the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Distinguish from codes for nerve injuries or fractures of the skull, as this code specifically targets muscle/tendon involvement.
