Lateral subluxation of unspecified patella, subs encntr

This code signifies a partial dislocation of the kneecap, specifically to the outer side, in an unspecified knee. It indicates that the patient is receiving follow-up care for this condition after the initial treatment phase.

Apply this code for patients presenting for ongoing management, such as physical therapy, follow-up imaging, or medication adjustments, for a previously diagnosed lateral patellar subluxation. This includes situations where the patient is recovering or being monitored for recurrence.

• Ensure documentation clearly states "subsequent encounter" or similar language indicating ongoing care.
• Do not use for initial treatment of a new injury or for sequelae (late effects).
• Laterality (left or right) is unspecified with this code; if known, a more specific code should be chosen.
