Other spontaneous disruption of unsp ligament of right knee

This code signifies a non-traumatic tear or rupture of an unspecified ligament within the right knee joint. This disruption occurs without an external force or injury, often due to degenerative changes or underlying pathology affecting the ligament's integrity.

Apply this code when documentation indicates a spontaneous, non-traumatic tear of a right knee ligament where the specific ligament (e.g., ACL, PCL, MCL, LCL) is not identified. Supporting documentation would include physician notes detailing a sudden onset of knee pain, instability, or swelling without a reported injury mechanism, and imaging (MRI) confirming a ligamentous disruption without specifying the affected ligament.

• Ensure the documentation explicitly states "spontaneous" or "non-traumatic" to differentiate from traumatic ligamentous injuries.
• Avoid using this code if a specific ligament of the right knee is identified as disrupted; instead, use the more specific code for that ligament.
• Always query the provider if the documentation is unclear regarding the mechanism of injury or the specific ligament involved.
