Other dislocation of left patella, initial encounter

This code signifies a displacement of the kneecap from its normal position in the trochlear groove of the femur, specifically affecting the left knee, and is not further specified as a subluxation. This injury typically involves the patella moving completely out of alignment.

Apply this code when documentation clearly indicates a complete dislocation of the left patella, and the patient is receiving initial active treatment for the injury. This includes situations where the patient presents to the emergency department or a physician's office for the first time for this specific dislocation.

• Ensure the documentation specifies "dislocation" rather than "subluxation" for the left patella.
• Verify that this is the patient's first encounter for active treatment of this specific injury.
• Always review the medical record for laterality (left vs. right) and the encounter type (initial, subsequent, sequela).
