Pyrexia during labor, not elsewhere classified

This code signifies the presence of a fever (pyrexia) in a pregnant patient during the active process of labor. It indicates a systemic inflammatory response or infection that manifests as elevated body temperature during the peripartum period, excluding cases where the fever is specifically attributed to another condition classified elsewhere.

Apply this code when documentation indicates a maternal fever during labor without a more specific diagnosis for the fever, such as chorioamnionitis (O41.1-). This code is appropriate when the fever is noted as a symptom during labor and the underlying cause is either unknown or not separately classifiable.

• Do not use this code if a more specific cause for the fever during labor is documented (e.g., chorioamnionitis, urinary tract infection).
• Always sequence this code after the primary obstetric complication or condition if applicable.
• Ensure documentation clearly states the fever occurred during labor and is not merely a postpartum or antepartum fever.
