Unsp inj musc/tend at lower leg level, right leg, sequela

This code signifies a long-term or late effect of an unspecified injury to muscles or tendons in the right lower leg. This means the initial injury has healed, but the patient continues to experience residual symptoms or complications directly attributable to that past injury. The specific muscle or tendon involved is not documented.

Apply this code when a patient presents with a chronic condition, pain, or functional limitation in their right lower leg that is a direct consequence of a previous, unspecified muscle or tendon injury. This is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar tissue, functional impairment).
• Ensure documentation clearly links the current condition to a past, unspecified muscle/tendon injury of the right lower leg.
• Avoid using this code for acute injuries; instead, select an appropriate acute injury code from the S86.801- series.
