Other specified injury of right Achilles tendon, sequela

This code signifies a long-term or late effect resulting from a previous injury to the right Achilles tendon, where the specific nature of the injury is documented but does not fall into categories like rupture or strain. It indicates that the initial acute injury has resolved, but residual symptoms or conditions persist.

Apply this code when a patient presents with chronic pain, weakness, altered gait, or other persistent issues in the right Achilles tendon, and the medical record clearly links these symptoms to a past, non-rupture/non-strain injury. This is appropriate for follow-up encounters after the initial healing phase of the original injury.

• Always sequence this 'S' code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar tissue).
• Ensure documentation explicitly states "sequela" or "late effect" and specifies the right Achilles tendon.
• Verify that the original injury was not a rupture (S86.01-) or strain (S86.02-), as those have their own sequela codes.
