Nondisplaced osteochon fracture of right patella, sequela

This code signifies a previous injury to the right kneecap involving both bone and cartilage that was not displaced at the time of the fracture. The "sequela" designation indicates that this code is used to report a current condition or complication arising directly from that past osteochondral fracture.

This code is appropriate when a patient presents with ongoing symptoms or complications (e.g., chronic pain, stiffness, degenerative changes) directly attributable to a non-displaced osteochondral fracture of the right patella that occurred in the past and has since healed or is in a chronic state. It should be used for follow-up encounters related to the long-term effects of the injury.

• Always assign this code as a secondary diagnosis, following the code for the current condition being treated (e.g., M25.561 for chronic right knee pain).
• Ensure documentation clearly links the current symptoms or condition to the historical non-displaced osteochondral fracture of the right patella.
• Do not use this code for the initial treatment of an acute fracture; instead, use the appropriate acute fracture code.
