Strain of right Achilles tendon, initial encounter

This code identifies a non-traumatic overstretching or tearing of the fibers within the right Achilles tendon. It signifies an acute injury, typically characterized by pain, swelling, and impaired function of the affected ankle. The injury does not involve a complete rupture of the tendon.

Apply this code for patients presenting with a newly diagnosed strain of the right Achilles tendon, such as from overuse during physical activity or a sudden increase in exercise intensity. This is appropriate for the initial encounter for this specific injury, prior to any definitive treatment or follow-up care.

• Ensure documentation clearly specifies "strain" and not a "sprain" or "rupture" of the Achilles tendon.
• Verify the laterality is explicitly documented as "right."
• Confirm this is the patient's first visit for this particular injury to justify the "A" (initial encounter) seventh character.
