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

This code signifies a long-term consequence or late effect resulting from an unspecified injury to muscles or tendons in the lower leg. The specific muscle or tendon involved is not documented, nor is the side of the body affected. This code is used when the initial injury has resolved, but residual symptoms or conditions persist.

Apply this code when documenting a sequela of a past, unspecified muscle or tendon injury in the lower leg, such as chronic pain, weakness, or limited range of motion, where the original injury is no longer acute. This is appropriate when the medical record does not specify the exact muscle or tendon affected or the laterality.

• Always sequence this sequela code after the code for the residual condition being treated.
• Ensure documentation clearly indicates a "sequela" or "late effect" and that the original injury is no longer active.
• Avoid using this code if the specific muscle/tendon and laterality are known; instead, use a more specific S86.8- code with the appropriate seventh character for sequela.
