Fracture of coccyx, subs encntr for fracture with nonunion

This code signifies a patient presenting with a previously diagnosed fracture of the coccyx that has failed to heal properly, resulting in a nonunion. The encounter is for ongoing management or treatment of this persistent nonunion, not the initial injury.

Apply this code when a patient is seen for follow-up care of a coccyx fracture where imaging or clinical assessment confirms that the bone fragments have not united. This includes encounters for pain management, evaluation for surgical intervention, or other treatments aimed at addressing the nonunion.

• Always ensure documentation clearly states "nonunion" in relation to the coccyx fracture.
• Verify that this is not the initial encounter for the fracture; if it is, a different code for the initial encounter would be appropriate.
• Look for documentation of previous treatment attempts or a prolonged healing period without successful union.
