Spontaneous rupture of other tendons, right ankle and foot

This code signifies a non-traumatic tear of a tendon in the right ankle or foot, excluding the Achilles tendon. This rupture occurs without an external force or injury, often due to degenerative changes within the tendon. It represents a complete or partial separation of the tendon fibers.

Apply this code when documentation clearly indicates a spontaneous (atraumatic) rupture of any tendon in the right ankle or foot, such as the tibialis posterior, peroneal, or extensor tendons. This diagnosis is typically supported by imaging studies (e.g., MRI, ultrasound) confirming the rupture and a patient history ruling out acute trauma.

• Ensure documentation specifies "spontaneous" or "atraumatic" to differentiate from traumatic ruptures.
• Verify the specific tendon involved and laterality (right ankle/foot) are clearly stated.
• Do not use for Achilles tendon ruptures, which have their own specific codes.
