Other subluxation of unspecified knee, sequela

This code signifies a persistent or late-effect condition of an incomplete dislocation of an unspecified knee joint, where the joint surfaces are no longer in proper alignment but remain in partial contact. This subluxation is not a fresh injury but rather a long-term consequence of a previous knee injury or condition.

Apply this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a past subluxation of the knee, where the specific knee (left or right) is not documented. This includes chronic pain, instability, or functional limitations that are a direct result of the old subluxation.

• Ensure documentation clearly links the current condition to a previous subluxation event.
• Only use this code when the laterality of the affected knee is not specified in the medical record.
• Always sequence this code after the primary diagnosis describing the current manifestation or complication of the sequela.
