Unsp injury of musc/fasc/tend at neck level, sequela

This code signifies a long-term consequence or complication resulting from an unspecified injury to the muscles, fascia, or tendons in the neck region. It indicates that the initial acute injury has resolved, but the patient continues to experience residual effects such as chronic pain, weakness, or limited range of motion directly attributable to that past injury.

Use this code when documenting a patient presenting with a current condition that is a direct sequela of a previous, unspecified muscle, fascia, or tendon injury of the neck. Documentation should clearly state the link between the current symptoms and the old injury, often including terms like "due to old injury," "residual effects of," or "sequela of."

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation explicitly states the injury is "unspecified" and located at the "neck level."
• Do not use this code for acute or current injuries; those require codes from the initial encounter or subsequent encounter categories.
