Other dislocation of left patella, sequela

This code signifies a past dislocation of the left kneecap, where the patient is now experiencing residual effects or complications directly attributable to that prior injury. These sequelae can include chronic pain, instability, recurrent subluxations, or degenerative changes. The original dislocation event is no longer acute.

Apply this code when documentation clearly indicates a patient is being treated for long-term problems stemming from a previous left patellar dislocation. This is appropriate for follow-up visits addressing chronic symptoms or complications that developed after the initial injury healed. Do not use for acute dislocations.

• Requires a seventh character "S" to indicate sequela, signifying a late effect.
• Ensure documentation explicitly links the current condition to a prior left patellar dislocation.
• Code any current acute conditions or injuries separately.
