Anxiety and depression ICD-10 codes are some of the most frequently used codes in behavioral health, primary care, and medical billing. They’re also easy to get wrong. A chart that says “anxiety” can land on F41.9, F41.1, or an adjustment disorder code, depending on what the clinician documented.
This page lists the ICD-10-CM codes for anxiety and depression in the FY2027 code set, effective October 1, 2026. After the list, you’ll find how ICD-10-CM relates to the DSM-5-TR, a table of common anxiety codes, how F32 and F33 differ, and how to choose the most specific code. It’s a coding reference, not medical advice. Diagnosis is always the treating clinician’s call.
Key takeaways
- Most anxiety ICD-10-CM codes sit in category F41, with phobias in category F40. F41.1 covers generalized anxiety disorder, F41.0 covers panic disorder, and F41.9 covers anxiety disorder, unspecified, while F40 holds phobic anxiety disorders such as agoraphobia, social phobia, and specific phobias.
- Depression codes separate a single depressive episode (F32) from repeat episodes (F33). Both categories have codes for mild, moderate, and severe episodes and for remission. F32.A covers depression, unspecified, while F32.9 covers a single episode with no further detail.
- The right code is the most specific one the clinician’s documentation supports. The FY2027 ICD-10-CM guidelines call for codes at their highest number of characters and base code assignment on the provider’s documentation. These conditions also appear in codes for dementia, substance use, adjustment disorders, and antidepressant poisoning.
- TextExpander Snippets can store frequently used codes for insertion with a short abbreviation. The article’s examples include ;gad for F41.1 Generalized anxiety disorder and ;du for F32.A Depression, unspecified, so a code and its description can go into a note without searching a code list.
Anxiety and depression ICD-10 code list
The list below groups ICD-10 codes for anxiety and depression by category, from dementia to depression screening. The descriptions are the short titles CMS publishes for claims, so some words are abbreviated, such as “unsp” for unspecified, “w” for with, and “encntr” for encounter. A category such as F41 or a subcategory such as T43.2 isn’t billable on its own; claims need a code with every required character.

Keep frequently used codes ready with Snippets
Most behavioral health practitioners and coders use a small set of these ICD codes over and over. Looking up F41.1 or F33.1 again adds up across a day of notes and claims, and copying a code from an old note risks carrying over the wrong one.
With TextExpander, you save a code and its description once as a Snippet, then type a short abbreviation to insert it in your EHR, an email, or any other app where you type. A team can share one Snippet group of approved codes, so one update reaches everyone when a code changes. Learn more about medical note taking software for healthcare teams.
Snippets aren’t limited to codes. Psychiatric clinicians also save instructions they’ve already written well, so they don’t have to write them again:
TextExpander allows me to create detailed instructions that do not have to be recreated for each patient. Whether it is safety, or prescribing instructions or safety plans. I can easily add them to the body of a note and save time.
Bryan W., Psychiatric-Mental Health Nurse Practitioner
Keep personal health information out of the Snippet itself. Save the parts that stay the same, and use Fill-ins to type the details that change when you insert the Snippet. See how TextExpander approaches HIPAA before you set up Snippets for clinical work.
Tired of searching for ICD-10 codes? Try the Snippets below. Type the abbreviation and watch the code and description appear.
Start with these four, then add the codes your practice uses most. A pattern such as a semicolon plus the condition’s initials keeps abbreviations easy to remember.
Keep your go-to codes one abbreviation away
Save the diagnosis codes you use most as Snippets. Type a short abbreviation like ;gad, and the code and its description appear in your EHR, email, or claim notes. Add patient details with a Fill-in so they never live in the Snippet.

ICD-10-CM vs. DSM-5-TR: how the two systems relate
ICD-10 is the tenth revision of the International Classification of Diseases, formally the International Statistical Classification of Diseases and Related Health Problems, published by the World Health Organization. The United States uses a clinical modification, ICD-10-CM, maintained by the CDC’s National Center for Health Statistics and CMS. ICD-10-CM has been the required diagnosis code set for U.S. claims since October 1, 2015, and it’s updated every October 1.
The DSM-5-TR is the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, text revision, published by the American Psychiatric Association. It defines the diagnostic criteria that mental health clinicians use to diagnose mental disorders. The APA states that the DSM-5-TR includes “updated diagnostic criteria and ICD-10-CM codes,” and it publishes DSM-5-TR code updates when ICD-10-CM changes.
In practice, the two work together. A clinician uses the DSM-5-TR criteria to reach a diagnosis, and the claim reports the matching ICD-10-CM diagnosis code. The names don’t always match. The DSM-5-TR term social anxiety disorder corresponds to the social phobia codes in ICD-10-CM.
The two systems also group mental health disorders differently. The DSM-5 moved obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) out of its anxiety chapter, while ICD-10-CM keeps them in block F40 to F48, “Anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders.” That block also holds category F43, “Reaction to severe stress, and adjustment disorders,” and F44, “Dissociative and conversion disorders.”
Common ICD-10 codes for anxiety disorders
This table pulls together the anxiety codes and stress-related codes people search for most. Several, such as agoraphobia, social phobia, OCD, and PTSD, aren’t in the list above.
| Condition | ICD-10 code | Coding note |
|---|---|---|
| Generalized anxiety disorder | F41.1 | Also covers anxiety neurosis, anxiety reaction, anxiety state, and overanxious disorder |
| Panic disorder | F41.0 | Panic disorder with agoraphobia uses F40.01 instead |
| Agoraphobia | F40.00, F40.01, F40.02 | Unspecified, with panic disorder, or without panic disorder |
| Social anxiety disorder (social phobia) | F40.10, F40.11 | Social phobia, unspecified, or generalized |
| Specific phobia | F40.210 to F40.298 | Six-character codes by type, such as F40.243 for fear of flying |
| Obsessive-compulsive disorder | F42.2, F42.3, F42.4, F42.8, F42.9 | F42.3 is hoarding disorder and F42.4 is excoriation (skin-picking) disorder |
| Post-traumatic stress disorder (PTSD) | F43.10, F43.11, F43.12 | Unspecified, acute, or chronic. Category F43 covers reaction to severe stress |
| Acute stress reaction | F43.0 | F41 lists it in an Excludes2 note, so it’s coded separately |
| Adjustment disorder | F43.20 to F43.25, F43.29 | F43.22 with anxiety, F43.23 with mixed anxiety and depressed mood |
| Anxiety due to another medical condition | F06.4 | Code the underlying condition first |
| Other specified anxiety disorders | F41.8 | Includes mixed anxiety and depressive disorder |
| Anxiety disorder, unspecified | F41.9 | Anxiety NOS (not otherwise specified) |
Generalized anxiety disorder shows how much detail stands behind one code. The DSM-5 GAD criteria, summarized by SAMHSA, describe excessive anxiety and worry, occurring more days than not for at least six months, that the person finds difficult to control. In adults, the worry comes with three or more of six symptoms: restlessness or feeling on edge, being easily fatigued, difficulty concentrating, irritability, muscle tension, and sleep disturbance. The symptoms must cause clinically significant distress or functional impairment and can’t be better explained by a substance, other medical conditions, or another mental disorder.
When a note mentions anxiety symptoms but doesn’t document the full diagnostic criteria for a specific anxiety disorder, F41.9 is usually the code the record supports.
Depression codes: F32, F32.A, and F33
ICD-10-CM splits depression codes by whether the patient has had one episode or more than one. F32 codes describe a single depressive episode. F33 codes describe repeat episodes. Within each category, the fourth and fifth characters capture severity (mild, moderate, or severe), whether psychotic symptoms are present, and whether the condition is in partial or full remission. F32 has an Excludes1 note for the F33 codes, so the two categories generally aren’t reported together.
F32.A, Depression, unspecified, is the code people look up most on this page. It was added to ICD-10-CM on October 1, 2021, and it covers “Depression NOS” and “Depressive disorder NOS.” Before F32.A existed, unspecified depression was coded to F32.9. Today, the two codes mean different things:
- F32.A applies when the provider documents depression without identifying it as a major depressive episode.
- F32.9 applies when the clinician documents a single major depressive episode but doesn’t specify severity or remission status.
Other depression codes depend on cause and context. Bipolar disorder with a current depressed episode uses F31 codes. Depression due to another medical condition uses F06.31 or F06.32, postpartum depression uses F53.0, and premenstrual dysphoric disorder uses F32.81. When anxiety and depression appear together, each documented condition generally gets its own code, unless the clinician documents mixed anxiety and depressive disorder, which ICD-10-CM places under F41.8.
How to choose the most specific anxiety or depression code
ICD codes are only as specific as the documentation behind them. The FY2027 ICD-10-CM Official Guidelines for Coding and Reporting set out three coding guidelines that matter most for mental health coding:
- Code to the full length. Section I.B.2 says, “Diagnosis codes are to be used and reported at their highest number of characters available.” F40.24 needs a sixth character, and T43 codes need a seventh character for the encounter.
- Code from the provider’s documentation. Section I.B.14 says, “Code assignment is based on the documentation by the patient’s provider.” Coders shouldn’t infer a diagnosis from symptoms alone.
- Code to the level of certainty. Section I.B.18 says, “Each healthcare encounter should be coded to the level of certainty known for that encounter.” An unspecified code is correct when that’s all the clinician knows at the visit, and a more specific code can replace it once a specific diagnosis is made.
Payer documentation requirements vary, but good clinical documentation makes the correct code clear. For these conditions, that means the diagnosis, severity, single or repeat episode, remission status, any identifiable stressor, and any link to substance use or another medical condition. Notes that describe symptoms, duration, and functional impairment also support the treatment plan and, when there’s more than one condition, the choice of primary diagnosis. Check Excludes notes as well, such as the F41 note on acute stress reaction (F43.0).
The F10 to F19 codes in the list each work as a combination code. F10.180, for example, reports both alcohol abuse and the alcohol-induced anxiety disorder. For more ways to cut errors, see how to improve medical coding accuracy.
Detailed documentation takes time, which is where reusable text helps:
I’m a psychiatrist and have to write highly detailed assessment notes and emails on a daily basis. With TextExpander I can create professional-looking documents in 1/3 the time it took to type them by hand, and it’s faster than dictation. TextExpander has completely transformed the way I work for the better.
Xenia Borue, MD, PhD, Psychiatrist, Pittsburgh, PA
The details that set one diagnosis apart still come from the clinician. Reusable text covers the wording that stays the same, which leaves more time for the parts of the note that need clinical judgment. If your practice is also reviewing its records system, see Choosing the right EHR software for your mental health practice.

Frequently asked questions
What is the ICD-10 code for F41 8?
F41.8 is the ICD-10-CM code for Other specified anxiety disorders. It's a billable code for a disorder the clinician documents that has no dedicated code elsewhere in category F41. The ICD-10-CM tabular list includes three inclusion terms under F41.8: anxiety depression (mild or not persistent), anxiety hysteria, and mixed anxiety and depressive disorder. F41.8 has not changed since ICD-10-CM took effect in October 2015, including in the FY2027 code set.
What is the ICD-10 code for situational anxiety?
ICD-10-CM has no code titled "situational anxiety." The closest category is F40.24, Situational type phobia, but F40.24 is a subcategory, not a billable code. A complete code needs a sixth character: F40.240 for claustrophobia, F40.241 for acrophobia, F40.242 for fear of bridges, F40.243 for fear of flying, or F40.248 for other situational type phobia. When anxiety is a reaction to a stressful life event rather than a phobia, F43.22, Adjustment disorder with anxiety, may match the provider's documentation instead.
What is the ICD-10 code for F41?
F41 is the ICD-10-CM category for Other anxiety disorders, and it isn't billable on its own. Claims need one of its five specific codes: F41.0 for panic disorder, F41.1 for generalized anxiety disorder, F41.3 for other mixed anxiety disorders, F41.8 for other specified anxiety disorders, or F41.9 for anxiety disorder, unspecified. The category excludes anxiety in acute stress reaction (F43.0), transient adjustment reaction (F43.2), neurasthenia (F48.8), psychophysiologic disorders (F45.-), and separation anxiety (F93.0).
What is the code F41 9 for anxiety disorder?
F41.9 is the ICD-10-CM code for Anxiety disorder, unspecified. It's a billable code for anxiety documented without enough detail to assign a more specific diagnosis, and the tabular list places "anxiety NOS" (not otherwise specified) under it. When the clinician documents a specific condition, such as generalized anxiety disorder (F41.1) or panic disorder (F41.0), the more specific code applies instead of F41.9.
What is diagnosis code F41 3?
F41.3 is the ICD-10-CM code for Other mixed anxiety disorders. It's a billable code within category F41, Other anxiety disorders, and it has no inclusion terms of its own in the tabular list, so its use depends on the provider documenting a mixed anxiety presentation. F41.3 is separate from mixed anxiety and depressive disorder, which ICD-10-CM lists under F41.8, Other specified anxiety disorders.
What is f41 2 anxiety?
F41.2, Mixed anxiety and depressive disorder, is a code in the World Health Organization's international ICD-10, but it isn't a valid code in ICD-10-CM, the version used for diagnosis coding in the United States. In ICD-10-CM, category F41 moves from F41.1 to F41.3, and mixed anxiety and depressive disorder appears as an inclusion term under F41.8, Other specified anxiety disorders. When a clinician documents separate anxiety and depressive disorders, each documented condition generally gets its own code.
What is an F31 9 diagnosis?
F31.9 is the ICD-10-CM code for Bipolar disorder, unspecified. It's a billable code used when bipolar disorder is documented without further detail about the current episode, and the tabular list includes "manic depression" under it. When the documentation is more specific, a code from elsewhere in category F31 applies, such as F31.32 for bipolar disorder, current episode depressed, moderate, or F31.76 for bipolar disorder in full remission, most recent episode depressed.
What is F33 1 major depressive disorder?
F33.1 is the ICD-10-CM code for Major depressive disorder, recurrent, moderate. It's a billable code for repeat major depressive episodes when the current episode is documented as moderate. Neighboring F33 codes cover other severities: F33.0 for mild, F33.2 for severe without psychotic symptoms, and F33.3 for severe with psychotic symptoms. A first, single moderate episode uses F32.1 instead.
What is the ICD-10 code for F33 8?
F33.8 is the ICD-10-CM code for Other recurrent depressive disorders. It's a billable code, and the tabular list includes brief depressive episodes that keep returning under it. F33.8 applies when the clinician documents a repeating depressive disorder that doesn't fit codes F33.0 through F33.42 or F33.9, the unspecified code for repeat episodes. The code is unchanged in the FY2027 ICD-10-CM code set, effective October 1, 2026.
How can mental health professionals speed up intake and treatment notes?
Mental health professionals can speed up intake and treatment notes by reusing the parts that stay the same from patient to patient. That includes intake section headings, mental status exam structure, consent and safety plan wording, treatment plan language, and frequently used diagnosis codes. Many EHRs offer note templates, and a text expansion tool such as TextExpander lets clinicians insert saved text with a short abbreviation in the EHR, email, or documents. Keep patient details out of saved text and add them while writing each note. Clinicians still review every note and write the assessment in their own words.
