Puerperal psychosis

Puerperal psychosis is a severe, acute mental health disorder characterized by a rapid onset of psychotic symptoms, such as hallucinations, delusions, and disorganized thinking, occurring shortly after childbirth. This condition represents a psychiatric emergency requiring immediate intervention due to the high risk of harm to both the mother and infant.

This code is used when a patient develops a severe psychotic episode within the postpartum period, typically within the first few weeks after delivery. Documentation should clearly indicate the presence of psychotic features (e.g., hallucinations, delusions, severe mood lability, disorganized behavior) and a temporal relationship to childbirth.

• Differentiate from postpartum depression with psychotic features (F53.0) which is less severe and primarily mood-based.
• Ensure documentation specifies "psychosis" rather than just severe mood disturbance.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
