Strain of muscles and tendons at ank/ft level, l foot, subs

This code indicates a non-traumatic overstretching or tearing of muscle fibers or tendons, other than the Achilles, located in the left ankle or foot. It specifically applies to a patient presenting for follow-up care after initial treatment for this injury. The strain is less severe than a complete rupture.

Use this code for patients returning for subsequent visits, such as physical therapy, re-evaluation, or medication refills, following an initial diagnosis and treatment of a left ankle or foot muscle/tendon strain. This applies when the injury is to a muscle or tendon not specifically classified elsewhere.

• Requires a 7th character "D" for subsequent encounter.
• Ensure documentation specifies "left foot" and "strain" of a muscle or tendon other than the Achilles.
• Distinguish from sprains (ligament injuries) and complete ruptures.
