Disp fx of lateral condyle of unsp femr, 7thM

This code describes a situation where the outer bony prominence at the end of the femur (thigh bone) near the knee has broken and the broken pieces are not aligned. This specific instance refers to a subsequent visit for an open fracture (where the bone broke through the skin) that is now failing to heal properly.

Use this code for follow-up encounters with a patient who previously sustained an open fracture (Type I or II) of the lateral femoral condyle, and current imaging or clinical assessment indicates that the fracture fragments are displaced and the bone is not uniting as expected. This code is appropriate when the patient is receiving ongoing treatment for the nonunion.

• Ensure documentation clearly specifies "nonunion" and "displaced" for the lateral condyle.
• Verify the original injury was an "open fracture type I or II" to justify the "M" seventh character.
• This code is for subsequent encounters, not the initial treatment of the fracture.
