ICD-10 Code F53.0 – Postpartum Depression (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F53.0 – Postpartum depression
What it is
F53.0 identifies depression occurring in the postpartum period. Use it for a mood disorder that begins after childbirth and is documented as postpartum depression.
Clinical signs
Common findings include persistent low mood, loss of interest, fatigue, sleep disturbance, poor concentration, and feelings of guilt or worthlessness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents postpartum depression, postnatal depression, or depression tied to the puerperium. It is appropriate when the record clearly links the depressive episode to the postpartum period. Check documentation if the timing or diagnosis is unclear.
Do not use for
Do not use it for depression unrelated to childbirth or for a general depressive disorder without postpartum linkage. Check documentation if the note describes anxiety, psychosis, or another postpartum condition instead.
Coding tip
Confirm that the provider explicitly connects the depression to the postpartum period before assigning F53.0.
