Oth spontaneous disruption of capsular ligament of left knee

This code signifies a non-traumatic tear or rupture of the joint capsule ligaments in the left knee. This disruption occurs without an external force or injury, often due to degenerative changes or underlying systemic conditions affecting connective tissue.

Apply this code when documentation clearly indicates a spontaneous (non-traumatic) disruption of the capsular ligaments of the left knee. This diagnosis is typically supported by imaging studies (e.g., MRI) showing the tear and a patient history ruling out acute injury.

• Ensure documentation specifies "spontaneous" and not traumatic to differentiate from injury codes.
• Verify the affected side is explicitly stated as "left knee."
• Distinguish from specific ligamentous tears (e.g., ACL, PCL), as this code refers to the general joint capsule.
