F32.A or F32.9?
The two codes sit next to each other and get mixed up all the time. The ICD‑10‑CM index separates them by one word. "Depression" on its own, "depressive disorder" and "depressive state" lead to F32.A. "Depression, major" and "disorder, depressive, major" lead to F32.9, which is major depressive disorder, single episode, unspecified.
So F32.9 is a diagnosis of major depression with the severity left out, and F32.A is depression that hasn't been characterized as major depression at all. If F32.9 shows up on a claim for a client whose notes only ever say "depression", that's often a habit left over from before 2021, when F32.9 was the code for depression with no further detail.
What the clinician documented | Code |
|---|---|
Depression, or depressive disorder, with no further detail | F32.A |
Major depressive disorder, single episode, severity not stated | F32.9 |
Major depressive disorder, single episode, moderate | F32.1 |
Major depressive disorder, recurrent, moderate | F33.1 |
Dysthymic disorder (persistent depressive disorder) | F34.1 |
Adjustment disorder with depressed mood | F43.21 |

When F32.A is the right code
F32.A fits the early part of care, before the picture is clear. A referral that just says "depression", a first session where you haven't yet asked about past episodes, a client who screens positive but hasn't had a full diagnostic assessment: in each case, the honest code is the unspecified one.
It stops fitting once you know more. When the notes establish major depressive disorder, its severity and whether it's a first episode, the code should say so too. A coder can only report what the clinician documented, so the update starts in the note, not on the claim.
What to document
- The symptoms in the client's words and your observations, with how long they've been present.
- Any screening score with its date, for example a PHQ-9.
- What is still unknown: previous episodes, severity, other diagnoses being ruled out.
- The plan to clarify the diagnosis, and when.
Here is how that reads in a progress note for a fictional client:
Example. Client reports low mood, poor sleep and less interest in activities for about two months. The referral from primary care lists "depression". PHQ‑9 is 14 today. History of earlier episodes not yet taken. Working diagnosis: depression, unspecified (F32.A). Plan: complete the diagnostic assessment next session and update the diagnosis.

Billing F32.A with psychotherapy codes
F32.A goes on the claim as the diagnosis for the session. The CPT codes it's most often billed with in outpatient therapy:
CPT code | Used for |
|---|---|
90791 | The first diagnostic evaluation, often the visit where F32.A is first recorded |
90832, 90834, 90837 | Individual psychotherapy, by session length |
96127 | A brief standardized emotional or behavioral assessment, such as a PHQ-9 |
More on each: 90791, 90832, 90837 and 96127. If F32.A stays on every claim for months while the notes describe a fully assessed depression, update the code. The notes and the claim should tell the same story.

Common mistakes with F32.A
- Using F32.9 for plain depression. F32.9 means major depressive disorder. Depression with no further detail is F32.A.
- Keeping F32.A after the diagnosis is clear. Once the notes describe a major depressive episode, its severity and course, code that instead.
- Reporting F32.A with F33 or F31. Category F32 has an Excludes1 note for recurrent depressive disorder and bipolar disorder, so they aren't reported together.
- Reaching for depression when the picture is an adjustment disorder. Low mood that follows a clear stressor and fits adjustment disorder is F43.21. Because the F32 note is an Excludes2, both codes can be reported only when both conditions are actually present.
Checked against the FY2027 ICD‑10‑CM code set from CMS on October 12, 2026. F32.A did not change this year.
