The diagnosis gap

The DSM-III removed “postpartum” in 1980. It returned in the 1994 DSM-IV as the specifier “with postpartum onset” (within 4 weeks of birth). The 2013 DSM-5 changed it to “with peripartum onset,” covering pregnancy through 4 weeks after delivery. There is still no standalone postpartum diagnosis.

This Is Why, Part 3 of 7: Psychiatry erased postpartum illness

This one stopped me cold.

Psychosis connected to childbirth was listed in the second edition of psychiatry’s diagnostic manual, the DSM-II, in 1968. Then, in the DSM-III in 1980, the word “postpartum” was removed. It stayed out for 14 years. (Psychiatrist.com)

The psychiatrist who wrote that history argues it produced a generation of American psychiatrists who disregarded mental illness tied to childbearing. If the manual doctors train on doesn’t name a condition, it’s much harder to study, bill for, or build services around it.

When postpartum illness returned in 1994 (DSM-IV), it wasn’t as its own diagnosis. It came back as a label added to other diagnoses, “with postpartum onset,” and only if symptoms began within 4 weeks of delivery. (MGH Center for Women’s Mental Health)

In 2013, DSM-5 changed the label to “with peripartum onset” so it covers pregnancy too. But it still applies only to symptoms starting during pregnancy or within 4 weeks after birth. (Psychiatric Times)

Many clinicians had hoped the window would extend to 6 months, because so many mothers start struggling after that first month. On paper, those mothers don’t fit.

And perinatal anxiety, OCD, and PTSD? The specifier applies to mood episodes. Anxiety disorders, often more common than depression in this period, aren’t covered by it at all (UTHSC clinical training, 2026).

To this day, there is no standalone postpartum diagnosis in the DSM.

This is why.
