Other spontaneous disruption of unsp ligament of unsp knee

This code signifies a non-traumatic tear or rupture of an unspecified ligament within an unspecified knee joint. It indicates a spontaneous disruption, meaning the injury occurred without an external force or accident. The exact ligament involved and the specific knee affected are not documented or are unknown.

Use this code when documentation clearly states a spontaneous disruption of a knee ligament, but the specific ligament (e.g., ACL, PCL, MCL, LCL) is not identified, and the laterality of the knee is also unspecified. This code is appropriate when the physician's notes indicate a ligamentous tear that was not caused by an acute injury or trauma.

• Avoid using this code if the specific knee (right or left) or the specific ligament is documented; instead, choose a more precise code.
• This code should be a last resort when specificity is truly lacking in the medical record.
• Query the provider for more detailed information regarding the affected ligament and laterality whenever possible to allow for more specific coding.
