Spontaneous rupture of flexor tendons, right ankle and foot

This code signifies a non-traumatic tear or break in the flexor tendons located in the right ankle or foot. This condition typically results from degenerative changes within the tendon rather than an acute external injury. Patients often present with sudden pain, swelling, and impaired ability to flex the affected digits or foot.

Apply this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of a flexor tendon in the right ankle or foot. This is appropriate for conditions like a ruptured tibialis posterior tendon or flexor hallucis longus tendon where no external force caused the tear. Physician notes must specify the spontaneous nature of the rupture and the affected anatomical site.

• Differentiate carefully between spontaneous and traumatic ruptures; traumatic ruptures are coded differently.
• Ensure the laterality (right) is clearly documented and matches the code.
• Verify the specific tendon involved if possible, though this code covers all flexor tendons in the specified area.
