Sprain of unsp cruciate ligament of right knee, sequela

This code signifies a long-term or late effect resulting from a sprain of an unspecified cruciate ligament in the right knee. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past sprain. This could include chronic pain, instability, stiffness, or functional limitations.

Use this code when documenting a patient presenting with persistent issues in their right knee that are directly linked to a previously diagnosed and treated cruciate ligament sprain, where the specific ligament (anterior or posterior) was not identified. This is appropriate for follow-up visits addressing chronic sequelae rather than the acute injury itself.

• Always link this sequela code to an external cause code (V00-Y99) if the original injury's cause is known and relevant.
• Ensure documentation clearly states the "sequela" nature of the current condition and its direct relationship to a past right knee cruciate ligament sprain.
• Do not use this code for acute or subacute sprains; those require codes from the initial encounter or subsequent encounter categories.
