Sprain of anterior cruciate ligament of right knee, sequela

This code signifies a past injury to the anterior cruciate ligament (ACL) in the right knee, where the patient is now experiencing residual effects or complications directly attributable to that prior sprain. These sequelae could include chronic instability, pain, stiffness, or functional limitations that persist long after the initial acute injury has healed. It indicates that the current patient presentation is a direct consequence of the original ACL sprain.

Use this code when documenting a patient presenting with ongoing symptoms or conditions in the right knee that are a direct result of a previously sustained ACL sprain. This is appropriate for chronic conditions, long-term complications, or late effects of the initial injury, rather than the acute sprain itself. It would be used when the original injury is no longer acute but its impact is still being managed.

• Always ensure documentation clearly links the current symptoms or condition to a previous ACL sprain of the right knee.
• Do not use this code for an acute or current ACL sprain; instead, refer to the appropriate acute injury codes.
• This code requires a seventh character 'S' to indicate sequela, which is crucial for correct reporting.
