Nondisp fx of navicular of unsp foot, subs for fx w malunion

This code signifies a follow-up encounter for a patient who previously sustained a fracture of the navicular (scaphoid) bone in an unspecified foot, and the fracture is now healing incorrectly, resulting in a malunion. This indicates a complication where the bone fragments have united in an abnormal position, potentially leading to pain, deformity, or functional impairment.

Use this code when documenting a patient's visit for ongoing management or evaluation of a previously diagnosed navicular fracture of the foot that has healed with malunion. This applies to encounters after the initial treatment phase, where the focus is on addressing the consequences of the improper healing.

• Ensure documentation clearly specifies "malunion" as the healing complication.
• Verify that the affected foot (left, right, or unspecified) is documented.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
