Displaced comminuted fracture of unsp patella, sequela

This code signifies a past injury to the kneecap that was characterized by multiple bone fragments and was out of its normal alignment. The "sequela" designation indicates that the patient is currently experiencing a residual condition or complication directly resulting from this old fracture.

Apply this code when documenting chronic pain, limited range of motion, instability, or other long-term effects stemming from a previously sustained, displaced comminuted patellar fracture. This code is appropriate for follow-up visits where the primary focus is managing these persistent issues.

• Always sequence this code after the code for the specific sequela being treated (e.g., M25.561 for chronic knee pain).
• Ensure documentation clearly links the current symptoms to the old patellar fracture.
• Do not use this code for acute or initial treatment of the fracture; it is exclusively for sequelae.
