Unspecified dislocation of left knee, initial encounter

This code signifies a dislocation of the left knee joint where the specific type of dislocation (e.g., patellar, tibiofemoral) is not documented. It indicates that the knee joint has been displaced from its normal alignment, affecting the left lower extremity. This is the first time the patient is being treated for this particular injury.

This code is appropriate for initial encounters when a patient presents with a dislocated left knee, but the physician documentation does not specify the exact anatomical structures involved in the dislocation. It is used when the diagnosis is clearly a knee dislocation, but further detail is lacking or not yet determined.

• Ensure the documentation explicitly states "left knee" and "dislocation" without further specification of the dislocation type.
• Verify that this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Avoid using this code if the documentation specifies a patellar dislocation, tibiofemoral dislocation, or other specific knee dislocation types.
