Postprocedural fever

This code signifies an elevated body temperature that develops after a medical or surgical procedure, without evidence of infection. It represents a systemic inflammatory response to the intervention itself, rather than a pathogen.

Use this code when documentation clearly indicates fever occurring post-procedure, and infectious causes have been ruled out or are not yet confirmed. This is often seen in the immediate postoperative period or following invasive diagnostic procedures.

• Ensure documentation explicitly states "postprocedural fever" or similar, and that infection is not the primary diagnosis.
• Review "Excludes1" notes carefully to avoid miscoding with postprocedural infection, posttransfusion fever, or postvaccination fever.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the initial procedure or its complications.
