Unsp inj musc/fasc/tend at forarm lv, left arm, sequela

This code signifies a long-term complication or late effect resulting from an unspecified injury to muscles, fascia, or tendons in the left forearm. The original injury is no longer acute, and the patient is experiencing residual symptoms or conditions directly attributable to that past trauma.

Use this code when documenting a sequela (e.g., chronic pain, weakness, limited range of motion, scar tissue formation) in the left forearm that is definitively linked to a previous, unspecified muscle, fascia, or tendon injury. This applies when the acute phase of the initial injury has passed, and the current encounter addresses these persistent issues.

• Always sequence this "S" code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past, unspecified injury of the left forearm muscles, fascia, or tendons.
• Avoid using this code for acute injuries; it is strictly for late effects.
