Other subluxation of right patella, initial encounter

This code signifies a partial dislocation of the right kneecap that is not explicitly classified as recurrent, congenital, or traumatic. It indicates that the patella has moved out of its normal groove but remains partially in contact with the femur.

Apply this code for initial encounters where a patient presents with symptoms of a right patellar subluxation, and the physician's documentation does not specify the subluxation as recurrent, congenital, or due to a direct traumatic event. This is appropriate for first-time occurrences or when the etiology is unclear beyond a general subluxation.

• Always verify laterality (right) and encounter type (initial) from the medical record.
• Distinguish from complete dislocations (S83.1-) and recurrent subluxations (S83.00-).
• Ensure documentation supports "other" subluxation, meaning it's not specified as recurrent, congenital, or traumatic.
