Recurrent subluxation of patella, unspecified knee

This code signifies the repeated, partial dislocation of the kneecap (patella) from its normal position within the trochlear groove, where the specific knee affected is not documented. This condition typically results in pain, instability, and a feeling of the knee "giving way."

Apply this code when documentation indicates a history of recurrent patellar subluxation without specifying laterality (left or right knee). This is appropriate when the physician's assessment or patient history confirms multiple episodes of the patella partially slipping out of place.

• Requires documentation of "recurrent" or "history of multiple episodes" of subluxation.
• Avoid using this code if laterality (left or right knee) is specified; instead, use the more specific M22.11 or M22.12.
• Consider co-reporting with codes for associated pain (e.g., M25.56-) or other knee derangements if documented.
