Lateral dislocation of right patella, initial encounter

This code signifies a displacement of the right kneecap to the outer side of the knee joint. This injury typically involves the patella slipping out of its normal groove, often causing pain, swelling, and an inability to straighten the leg.

Apply this code when documenting the initial treatment for a patient presenting with a newly diagnosed lateral dislocation of the right patella. This includes emergency department visits, initial orthopedic consultations, or primary care encounters where the dislocation is first identified.

• Ensure documentation clearly specifies the right knee and that this is the first time the patient is being treated for this particular dislocation.
• Distinguish from recurrent dislocations, which would require a different seventh character.
• Look for associated injuries, such as ligamentous tears or fractures, which would necessitate additional codes.
