Unspecified subluxation of left knee, subsequent encounter

This code indicates an incomplete dislocation of the left knee joint where the joint surfaces are no longer in proper alignment, but remain in partial contact. The specific bone involved in the subluxation is not documented. This code is used for encounters following the initial treatment of the injury.

This code is appropriate for follow-up visits, rehabilitation sessions, or subsequent evaluations for a left knee subluxation where the exact nature of the subluxation (e.g., patellar, tibiofemoral) was not specified in the medical record. It signifies that the patient is receiving ongoing care for this previously diagnosed condition.

• Ensure the documentation clearly states "left knee" and "subluxation" without further specification of the affected bone.
• The "D" seventh character is crucial and indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use this code for initial treatment of the injury; refer to the "A" seventh character for initial encounters.
