Lateral subluxation of unspecified patella, init encntr

This code signifies an incomplete dislocation of the kneecap, specifically when it shifts towards the outside of the leg. It indicates that the patella has moved out of its normal groove but has not fully separated from the joint. The "unspecified" nature means the laterality (left or right) is not documented.

Use this code for initial encounters with patients presenting with a first-time or recurrent lateral patellar subluxation where the specific knee (left or right) is not documented. This is appropriate for acute injuries or when a patient first seeks treatment for this condition.

• Ensure documentation clearly states "subluxation" rather than "dislocation" for accurate code assignment.
• Verify that the encounter is indeed the "initial encounter" for this specific injury; subsequent care would require a different seventh character.
• Look for documentation of laterality (left or right) to assign a more specific code if available.
