Mixed anxiety and depressive disorder is F41.8, and it is billable as written. Two things make this one hard to find. It sits under a heading that does not mention it — F41.8 is titled other specified anxiety disorders, with mixed anxiety and depressive disorder listed as an inclusion term. And the obvious-looking alternative is wrong: F41.3 is other mixed anxiety disorders, which mixes anxiety with something other than depression. Below: when F41.8 is right, when to code both conditions separately instead, 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.
The names invite the mistake. ICD-10-CM lists three inclusion terms under F41.8:
F41.3 carries no inclusion terms at all and is titled other mixed anxiety disorders — anxiety mixed with a condition that is not depression. If the picture is anxiety plus depression, F41.8 is the code.
| Code | Title | Billable? |
|---|---|---|
| F41 | Other anxiety disorders (category header) | No |
| F41.0 | Panic disorder [episodic paroxysmal anxiety] | Yes |
| F41.1 | Generalized anxiety disorder | Yes |
| F41.3 | Other mixed anxiety disorders | Yes |
| F41.8 | Other specified anxiety disorders | Yes |
| F41.9 | Anxiety disorder, unspecified | Yes |
F41.2 is absent from ICD-10-CM: the family runs .0, .1, .3, .8, .9.
F41.8 describes a presentation where anxiety and depressive symptoms are both present and neither is severe enough to stand as a diagnosis in its own right. That is what the inclusion term “anxiety depression (mild or not persistent)” is signalling.
Where the record does support both diagnoses independently — a major depressive episode and generalized anxiety disorder, each meeting criteria — the accurate coding is both codes, not F41.8: for example F33.1 alongside F41.1. Collapsing two established diagnoses into F41.8 understates the record, and it is the weaker choice if the claim is reviewed.
There is a second boundary worth knowing. Persistent anxiety depression is F34.1, in the persistent mood disorder family, and ICD-10-CM records this as an Excludes2 against F41.8. Persistence is what decides between them: F41.8 is for the mild or non-persistent picture, F34.1 for one that has continued for years.
This is the part that causes the confusion, and it is worth being plain about. DSM-5 has no mixed anxiety and depressive disorder. The diagnosis was proposed for DSM-5 and was not included in the final manual, so a clinician assessing strictly against DSM-5 criteria never arrives at it.
What DSM-5 offers instead is the with anxious distress specifier on a depressive or bipolar episode — which does not change the ICD-10-CM code. So the DSM-5 route for a depressed patient with prominent anxiety is an F32 or F33 code with that specifier documented, while the ICD-10-CM route offers F41.8 as a code in its own right.
Both are defensible. What causes problems is using F41.8 as shorthand for “depressed and anxious” when the record actually establishes a major depressive episode — the specific code is more accurate and better supported.
| 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. F41.8 is a specific code and valid for submission. F41 on its own is a category header and is not.
F41.8. ICD-10-CM lists mixed anxiety and depressive disorder as an inclusion term under it, along with anxiety depression that is mild or not persistent.
F41.3 is other mixed anxiety disorders — anxiety mixed with something that is not depression. Mixed anxiety and depressive disorder is an inclusion term under F41.8, not F41.3.
Code both separately when the record supports each diagnosis independently. F41.8 is for a picture where anxiety and depressive symptoms are both present but neither stands alone as a diagnosis.
No. It was proposed for DSM-5 and not included. DSM-5 offers a with anxious distress specifier on a depressive episode instead, which does not change the ICD-10-CM code.
