Postpartum depression is F53.0, and it is billable as written. Two neighbours are routinely coded here by mistake and both are Excludes1, meaning they are never reported alongside F53.0. Postpartum dysphoria — the transient low mood of the first days, often called the baby blues — is O90.6, in the obstetric chapter rather than the mental health one. And a postpartum depressive episode with psychotic features leaves F53 altogether. Below: the table, both exclusions and the CPT pairings.
This page is billing and administrative reference. It describes what a code means and whether it can be submitted. It is not clinical advice and does not tell anyone what to diagnose.
| Code | Title | Billable? |
|---|---|---|
| F53 | Mental and behavioral disorders associated with the puerperium (category header) | No |
| F53.0 | Postpartum depression | Yes |
| F53.1 | Puerperal psychosis | Yes |
ICD-10-CM lists postnatal depression and postpartum depression NOS as inclusion terms under F53.0, so those phrasings do not have codes of their own. Puerperal psychosis and postpartum psychosis both land on F53.1.
This is the one worth knowing. Postpartum dysphoria is O90.6, a code in the pregnancy and childbirth chapter, and ICD-10-CM marks it as an Excludes1 under F53. The transient mood disturbance of the first postpartum days is coded there, not as postpartum depression.
The practical consequence is the same one the insomnia codes have: a diagnosis from the O chapter reads as obstetric rather than behavioral health, which can decide which benefit is asked to pay and whether the rendering clinician is in network for it. Where a behavioral health benefit is carved out to a separate administrator, an O-chapter code can be routed somewhere the therapist is not contracted.
The second exclusion is broader and easy to miss. Mood disorders with psychotic features are excluded from F53 and code to the relevant F30–F33 code instead:
| Code | Title | Billable? |
|---|---|---|
| F32.3 | Major depressive disorder, single episode, severe with psychotic features | Yes |
| F33.3 | Major depressive disorder, recurrent, severe with psychotic symptoms | Yes |
| F31.2 | Bipolar disorder, current episode manic severe with psychotic features | Yes |
| F31.5 | Bipolar disorder, current episode depressed, severe, with psychotic features | Yes |
| F30.2 | Manic episode, severe with psychotic symptoms | Yes |
So a severe postpartum depressive episode with psychotic features is F32.3 or F33.3, not F53.0. Schizophrenia and the other psychotic disorders at F20–F29 are excluded from F53 for the same reason.
F53.0 has no severity character, so there is no unspecified-versus-specified choice inside F53 itself. The choice appears as soon as a case routes to the major depressive family instead — and there it matters. F32.9, major depressive disorder, single episode, unspecified is billable and frequently used, but it records no severity at all. Where the note establishes mild, moderate or severe, the specific code (F32.0, F32.1, F32.2) is the accurate one, and the unspecified code reads as a thinner record if the claim is reviewed.
The same applies to F53.0 versus F53.1. These are different conditions rather than severities of one, so neither is a fallback for the other: puerperal psychosis is not severe postpartum depression, and a depressive presentation without psychotic features is not F53.1.
DSM-5 has no separate postpartum depression diagnosis. It has a peripartum onset specifier applied to a major depressive episode, covering onset during pregnancy or in the four weeks after delivery. DSM-5-TR therefore points a clinician at an F32 or F33 code with a specifier, while ICD-10-CM offers F53.0 as a code in its own right.
That is a genuine mismatch rather than a naming difference, and it is why the same presentation is coded differently by different practices. A clinician assessing strictly against DSM-5 arrives at a major depressive episode with peripartum onset, which crosswalks to the F32 or F33 code for that episode's severity; the F53.0 route records the postpartum context in the code instead. Either can be defensible — what causes denials is mixing them, or reaching for F53.0 when psychotic features are documented.
| CPT | Service | Time |
|---|---|---|
| 90791 | Psychiatric diagnostic evaluation (no medical services) | — |
| 90832 | Individual psychotherapy | 16–37 minutes |
| 90834 | Individual psychotherapy | 38–52 minutes |
| 90837 | Individual psychotherapy | 53 minutes or more |
| 90847 | Family psychotherapy, patient present | 50 minutes typical |
| 90853 | Group psychotherapy | — |
A 50-minute session is 90834, not 90837 — 90837 begins at 53 minutes. CMS also sets a floor: psychotherapy under 16 minutes is not reported with these codes at all.

Yes. F53.0 is a specific code and valid for submission. F53 on its own is a category header and is not.
F53.0. ICD-10-CM lists postnatal depression and postpartum depression NOS as inclusion terms under it, so those phrasings use the same code.
O90.6 is postpartum dysphoria, the transient low mood of the first days after delivery, and it sits in the obstetric chapter. ICD-10-CM lists it as an Excludes1 under F53, so it is never coded alongside F53.0.
No. DSM-5 uses a peripartum onset specifier on a major depressive episode rather than a separate diagnosis, which points to an F32 or F33 code. ICD-10-CM offers F53.0 as a code in its own right.
Not with F53.0. Mood disorders with psychotic features are excluded from F53, so a severe episode with psychotic features codes to F32.3 or F33.3.
