Strain of left Achilles tendon, subsequent encounter

This code signifies a non-traumatic overstretching or tearing of the fibers of the Achilles tendon in the left leg, occurring during the healing or recovery phase of the injury. It indicates that the patient is receiving follow-up care, such as cast changes, physical therapy, or medication adjustments, for a previously diagnosed left Achilles tendon strain.

Apply this code when documenting subsequent encounters for a patient being treated for a left Achilles tendon strain. This includes visits for ongoing management, rehabilitation, or monitoring of the healing process after the initial injury has been assessed and treated. It is appropriate for any visit following the initial encounter for the same injury.

• Ensure the encounter is for follow-up care, not the initial diagnosis or treatment.
• Verify the laterality is specifically for the left Achilles tendon.
• Pair with an external cause code if the strain was due to an external event.
