Oth spon disruption of capsular ligament of right knee

This diagnosis code indicates a non-traumatic tear or rupture of one of the capsular ligaments surrounding the right knee joint. This disruption occurs spontaneously, meaning it is not due to an external force or injury but rather from an underlying degenerative process or weakness within the ligamentous structure itself.

Use this code when documentation specifies a spontaneous, non-traumatic disruption of a capsular ligament in the right knee. This often occurs in patients with pre-existing conditions that weaken connective tissues, such as inflammatory arthropathies or chronic degenerative changes. The physician's notes should clearly state the spontaneous nature of the tear and its location in the right knee.

• Differentiate from traumatic ligamentous injuries, which are coded under S83.- categories.
• Ensure the documentation specifies "spontaneous" or "non-traumatic" to support the use of this code.
• Verify the laterality (right knee) is clearly documented; separate codes exist for the left knee and unspecified knee.
