Lateral subluxation of left patella, subsequent encounter

This code indicates a partial dislocation of the kneecap, specifically on the outer side of the left knee, that is being addressed during a follow-up visit. The patella has moved out of its normal groove but is not fully displaced.

Use this code for encounters where a patient is receiving ongoing treatment for a previously diagnosed lateral subluxation of the left patella. This includes follow-up appointments for conservative management, physical therapy, or post-operative care after a surgical repair.

• Ensure documentation clearly specifies "left" patella and "lateral" subluxation.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use for initial injury or sequelae; those require different seventh characters.
