Strain of right Achilles tendon, sequela

This code signifies a long-term or late-effect condition resulting from a previous strain injury to the right Achilles tendon. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to the historical tendon strain, rather than an acute or current injury.

Apply this code when documenting a patient presenting with chronic pain, weakness, instability, or other persistent issues in the right Achilles tendon area, where these symptoms are a direct consequence of a previously sustained strain. This is appropriate for follow-up visits addressing the residual effects of an old injury.

• Always link this sequela code with an external cause code (V00-Y99) if the original injury's cause is known and documented.
• Do not use this code for acute or current Achilles tendon strains; those require codes from the S86.011A-D series.
• Ensure documentation clearly states the chronic nature of the condition and its direct relationship to a past Achilles tendon strain.
