ICD-10 Code F53.1 – Puerperal Psychosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F53.1 – Puerperal psychosis
What it is
F53.1 identifies a severe mental disorder that begins in the postpartum period. It is used when psychotic symptoms occur after childbirth and are documented as puerperal psychosis.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include hallucinations, delusions, severe mood disturbance, confusion, or marked disorganization after delivery.
When to use this code
Use this code when the record clearly states puerperal psychosis, postpartum psychosis, or a psychotic episode tied to the puerperal period. You should confirm the timing is after childbirth and that the provider links the condition to the postpartum state.
Do not use for
Do not use it for uncomplicated postpartum depression or anxiety without psychosis. Check documentation if the mental disorder is not explicitly postpartum or if another psychotic disorder is the documented diagnosis.
Coding tip
Code only when the provider documents psychosis in the puerperal period; otherwise, query for clarification.
