Other disorders of patella, right knee

This code signifies a diagnosis of a patellar disorder affecting the right knee that is not specifically classified elsewhere. It encompasses various conditions impacting the kneecap's structure or function, excluding those with more precise ICD-10-CM codes.

Apply this code when documentation indicates a right knee patellar pathology such as patellar maltracking, chondromalacia patellae (if not specified as a distinct condition), or other unspecified patellar derangements. Ensure the medical record clearly states the right knee is affected and that a more specific patellar disorder code is not applicable.

• Always verify laterality; this code is specific to the right knee.
• Avoid using this code if a more specific patellar disorder code (e.g., M22.0- for recurrent dislocation, M22.2- for patellofemoral disorders) is available and supported by documentation.
• Look for documentation of "other specified" or "unspecified" patellar issues when considering this code.
