Other subluxation of left patella, subsequent encounter

This code signifies a partial dislocation of the kneecap (patella) in the left knee, where the patella has moved out of its normal groove but not completely out of the joint. It covers various types of subluxations that are not specifically classified elsewhere, such as recurrent or chronic instability.

Apply this code for follow-up encounters when a patient is receiving ongoing treatment or evaluation for a previously diagnosed "other" subluxation of the left patella. This includes visits for physical therapy, medication management, or re-evaluation of the patellar instability after the initial injury or acute phase has passed.

• Ensure documentation clearly specifies "left" patella and "subluxation" rather than a complete dislocation.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Confirm that the subluxation is not further specified by a more precise code (e.g., recurrent, traumatic) before using this "other" category.
