You're sitting in front of the invoice, the session was intense, and one field is missing: the ICD-10 code. You roughly know what it was — but was it F32.1 or F33.1? F40.0 or F40.1? From 1 July 2026, this field becomes mandatory in Austria. This list helps you find the right code faster.
Who is this for? Clinical psychologists, psychotherapists, and anyone billing health insurance funds (ÖGK, BVAEB, SVS) or private clients in Austria.

In brief: what is ICD-10?
The ICD-10 (International Classification of Diseases, 10th Revision) is the WHO's international diagnostic classification. Chapter V covers mental and behavioural disorders — the F-codes. In Austria the BMSGPK 2024 version applies. From July 2026 the code becomes mandatory on invoices to health insurance funds, since this is how the fund maps your service to a billable category.
Important: ICD-10 is a billing classification, not a clinical decision tool. You make the clinical judgment as before — the code only translates it into a standardised form for the insurance fund.
F30–F39 — Mood (affective) disorders
By far the most common code group in clinical practice. Most therapists know these by heart within a few months.
| Code | Plain text | Practical example |
|---|---|---|
F32.0 | Mild depressive episode | First depressive episode, daily life still manageable |
F32.1 | Moderate depressive episode | Clearly reduced capacity, sleep disturbances |
F32.2 | Severe depressive episode without psychotic symptoms | Marked anhedonia, suicidal ideation |
F33.1 | Recurrent depressive disorder, current moderate | Recurring episodes across life phases |
F33.4 | Recurrent depressive disorder, currently in remission | Currently stable, prior episodes documented |
F34.1 | Dysthymia | Chronic, low-grade depressive mood across years |
F31.x | Bipolar affective disorder | Alternating manic and depressive phases |
F40–F48 — Anxiety, stress and somatoform disorders
The second most common group. Differential coding is often tricky — this is why a favourites list pays off.
| Code | Plain text | Practical example |
|---|---|---|
F40.0 | Agoraphobia | Fear of open spaces, crowds, public transport |
F40.1 | Social phobia | Fear of scrutiny in social situations |
F40.2 | Specific (isolated) phobias | Spiders, heights, needles, flying |
F41.0 | Panic disorder | Recurring panic attacks without trigger |
F41.1 | Generalised anxiety disorder | Free-floating anxiety over months |
F42 | Obsessive-compulsive disorder | Obsessions or compulsions causing distress |
F43.0 | Acute stress reaction | Reaction within hours/days of stressor |
F43.1 | Post-traumatic stress disorder | After trauma, flashbacks, avoidance |
F43.2 | Adjustment disorder | After breakup, job loss, diagnosis |
F45.0 | Somatisation disorder | Multiple unexplained physical symptoms |
F45.4 | Persistent somatoform pain disorder | Chronic pain, psychosocially co-determined |
F48.0 | Neurasthenia / fatigue syndrome | Persistent exhaustion (often called „burnout“ in everyday speech) |
Differential coding tip: Phasic symptoms point toward F32/F33. Chronic, low-grade symptoms point toward F34.1 or F48.0. This avoids the typical F32 over-coding.
F50 — Eating disorders
| Code | Plain text | Practical example |
|---|---|---|
F50.0 | Anorexia nervosa | BMI < 17.5, fear of weight gain |
F50.2 | Bulimia nervosa | Binge eating with compensatory behaviour |
F50.4 | Binge eating disorder | Without compensatory behaviour |
F51 — Non-organic sleep disorders
| Code | Plain text | Practical example |
|---|---|---|
F51.0 | Non-organic insomnia | Sleep onset or maintenance issues over weeks |
F51.5 | Nightmares | Recurring distressing dreams |
F60 — Personality disorders
| Code | Plain text | Practical example |
|---|---|---|
F60.3 | Emotionally unstable personality disorder | Borderline type or impulsive type |
F60.4 | Histrionic personality disorder | Theatrical presentation, attention-seeking |
F60.5 | Anankastic personality disorder | Strong perfectionism, need for control |
F60.6 | Anxious (avoidant) personality disorder | Withdrawal due to fear of criticism |
F10–F19 — Substance-related disorders
The trailing digit codes the severity: .0 acute intoxication, .1 harmful use, .2 dependence syndrome, .3 withdrawal state.
| Code | Plain text | Practical example |
|---|---|---|
F10.2 | Alcohol dependence | Clinically relevant alcohol dependence |
F11.2 | Opioid dependence | Heroin, methadone, opioid analgesics |
F17.2 | Tobacco dependence | Smoking cessation cases |
F90–F98 — Child & adolescent psychiatry
| Code | Plain text | Practical example |
|---|---|---|
F90.0 | Hyperkinetic disorder (ADHD) | School age, attention & impulse control issues |
F93.0 | Separation anxiety disorder | School avoidance, attachment to caregiver |
F95.x | Tic disorders | Transient or chronic (Tourette: F95.2) |
5 practical coding tips
- Mark your 5–10 most-used codes as favourites. 80 % of your invoices come from the same pool. In TimeInvoicer you star codes — they appear at the top.
- Set the code once when you create the client. For chronic cases the code rarely changes month to month. You save 30 seconds per follow-up invoice.
- Lead with the primary code in mixed presentations. The invoice reflects the primary focus of treatment.
- Take trailing digits seriously. F32.1 vs F32.2 is a major difference — clinically and in how the insurance fund sees the case.
- Update on remission. When F32.1 becomes F33.4 (in remission), put the change on the next invoice. This documents treatment success — valuable for renewal applications.
Note on responsibility: ICD-10 coding remains the clinical responsibility of the treating professional. This list does not replace diagnostic judgement — it only helps you find the right billing code. TimeInvoicer makes no diagnostic suggestions; the app only surfaces codes you have used yourself in the past.
How TimeInvoicer takes this off your hands
Looking up codes is not a job. It still costs hours every month — because most billing apps in Austria either have no integrated ICD-10 catalogue, or one that is unusable.
TimeInvoicer is built differently:
- Built-in catalogue with all F-codes (BMSGPK 2024) — offline on your device
- Full-text search: type „anxiety“ and get F40, F41 and all subcategories with plain text
- Favourites: your 5–10 most-used codes appear at the top
- Remembered per client: the code is pre-filled on the next invoice
- Voice command: „Invoice Maria, F33.1, March“ — and the invoice is ready
- No internet needed: codes live locally; client data never leaves your device
Code lookup is yesterday's problem.
