Other postoperative functional disorders

This code signifies a functional impairment or disturbance that arises as a direct consequence of a surgical procedure, but is not otherwise specified or classifiable. These disorders affect the normal operation of an organ or body system post-surgery, rather than being an infection, hemorrhage, or mechanical complication.

Apply this code when documentation clearly indicates a new functional deficit or dysfunction occurring after surgery, and more specific postoperative complication codes (e.g., infection, hemorrhage, dehiscence) do not apply. Examples include unexplained postoperative dysphagia, urinary retention without obstruction, or persistent nausea not due to ileus or medication.

• Always sequence this code after the primary diagnosis for which the surgery was performed, and after any more specific postoperative complications.
• Ensure documentation explicitly links the functional disorder to the preceding surgery; avoid using for unrelated conditions.
• Differentiate from codes for specific postoperative complications (e.g., 997.x series for complications affecting specific body systems) or adverse effects of drugs.
