Unspecified subluxation of unspecified knee, init encntr

This code signifies a partial dislocation of the knee joint where the specific bone involved (e.g., patella, tibia, femur) is not documented. It indicates that the joint surfaces are no longer in proper alignment but remain in partial contact, and this is the first time the patient is being treated for this condition.

Apply this code when the medical record clearly states a knee subluxation but lacks specificity regarding the anatomical site within the knee (e.g., "knee subluxation" without further detail). It is appropriate for the initial visit or treatment for this particular injury.

• Only use this code when the documentation explicitly states "unspecified" or provides no further detail regarding the subluxation's location within the knee.
• Always strive for greater specificity if available in the medical record; look for codes identifying patellar, tibiofibular, or other specific knee subluxations.
• The "A" at the end indicates an "initial encounter," meaning the patient is receiving active treatment for the condition.
