Spontaneous rupture of other tendons, right lower leg

This code signifies a non-traumatic tear of a tendon in the right lower leg, excluding the Achilles tendon, that occurs without an external force or injury. This rupture is often due to underlying degenerative changes within the tendon structure, leading to a sudden failure of the tissue.

Apply this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of a specific tendon in the right lower leg, such as the posterior tibial, peroneal, or anterior tibial tendon. Supporting documentation should specify the right lower leg and confirm the absence of an acute external injury or force.

• Ensure the documentation specifies "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Verify the affected tendon is located in the lower leg and is on the right side.
• Do not use for Achilles tendon ruptures; a more specific code exists for that condition.
