Unspecified subluxation of unspecified knee, subs encntr

This code signifies a partial dislocation of the knee joint where the specific type of subluxation (e.g., patellar, tibiofemoral) is not documented, nor is the affected knee specified. It is used for encounters following the initial treatment of the injury, indicating ongoing care or follow-up.

This code is appropriate for subsequent encounters when a patient presents with an unspecified knee subluxation, and the medical record lacks details regarding the specific anatomical site or type of subluxation. It is used when the patient is receiving routine follow-up care, physical therapy, or medication management for the previously diagnosed injury.

• Ensure the documentation clearly indicates an "unspecified" subluxation and an "unspecified" knee if this code is chosen.
• Only use this code for encounters after the initial treatment of the injury; for the initial encounter, a code from the "A" seventh character category would be appropriate.
• If the specific type of subluxation (e.g., patellar) or the affected knee (left/right) is documented, a more specific code should be selected.
