🧭 What is burnout? Medical and legal classification
In brief
"Burnout" describes a state of deep physical, emotional and mental exhaustion that usually builds up over months or years through ongoing overload – often, but not only, at work. However, the word is not a separate medical diagnosis in the German healthcare system. In the official ICD-10-GM classification, burnout is listed under the code Z73.0 "burn-out" – a so-called Z-code, meaning a factor that influences health status but does not itself describe an illness requiring treatment in the narrow sense.
This has real consequences: on the diagnosis Z73.0 alone, it is usually not possible in practice to substantiate a longer period of sick leave, coverage of psychotherapy costs, rehab or even a reduced earning capacity pension. In cases of exhaustion requiring treatment, doctors and psychotherapists therefore as a rule diagnose, in addition or instead, a separate condition from another ICD-10 chapter – most often a depressive episode (F32), an adjustment disorder (F43.2) or another stress-related disorder. This F-code, not the word "burnout", is the decisive basis in law and social insurance law.
Step by step
- Take it seriouslyPersistent exhaustion, sleep problems, cynicism about work or a feeling of being completely drained are a reason to seek medical or psychotherapeutic help – not a sign of weakness.
- See a GP or a psychotherapistBoth can issue a certificate of incapacity for work and arrange the necessary diagnostics.
- Pay attention to the diagnosis actually madeAsk which diagnosis or diagnoses are documented alongside or instead of Z73.0, as this decides on sick leave, cost coverage and later applications.
- Start treatmentDepending on severity: outpatient psychotherapy, accompanying medication or medical rehab (see the corresponding topic pages).
- Clarify the link to the workplaceIn parallel, check whether workplace stress factors play a role and whether talks with your manager, works council or company doctor make sense.
Deadlines
- "Burnout" alone is usually not a sufficient reason for the health insurer to cover costs – what matters is the underlying, separately diagnosed illness.
- ICD-11, which the WHO has been introducing internationally since 2022, classifies burnout (code QD85) even more clearly as a "factor" or "occupational phenomenon", not as an illness. In Germany, ICD-10-GM remains decisive for billing and social law (as of September 2026); the exact timetable for a complete changeover to ICD-11 in German social insurance could not be conclusively verified at the editorial deadline and is therefore deliberately not stated here.
- Do not hastily confuse burnout with depression – the two can occur together or merge into each other; medical/psychotherapeutic assessment is necessary.
- For the actual treatment of a depressive episode or adjustment disorder, see the Depression module.
In depth · legal basis, figures and practice – for advisers and professionals
Z-codes under ICD-10-GM
Chapter XXI of ICD-10-GM ("Factors influencing health status and contact with health services") contains so-called Z-codes. Z73.0 "burn-out" (burnout) is one of them. Z-codes may be coded, but on their own they generally do not give rise to incapacity for work or to entitlement to health insurance benefits such as guideline psychotherapy – this basically requires a diagnosis from the chapters that describe actual illnesses (e.g. Chapter V, "Mental and behavioural disorders", F00–F99).
In practice: F32, F43 & others alongside or instead of Z73.0
In medical and psychotherapeutic practice, Z73.0 is therefore often documented as an additional or secondary diagnosis alongside a depressive episode (F32.-), an adjustment disorder (F43.2) or occasionally a somatoform or neurasthenic disorder (F45.-, F48.0). Which diagnosis applies in an individual case is decided by the treating professional on the basis of the symptoms – this is not a mere formality but medically grounded, and at the same time the prerequisite for sick leave, sickness benefit, rehab or later applications.
ICD-11 and the international trend
In ICD-11 (code QD85), the WHO has described burnout as an "occupational phenomenon" in the chapter on factors influencing health status – expressly not classified as an illness. Germany is switching from ICD-10-GM to ICD-11 in healthcare and social insurance step by step; as of September 2026, ICD-10-GM remains decisive for billing, sick leave and social benefits. The exact timetable for the complete changeover could not be conclusively verified in the course of this research and is therefore deliberately not stated here.
Why this distinction matters for you
All further topic pages of this module – sick leave, sickness benefit, gradual return to work, rehab, reduced earning capacity pension – are tied in social law to a separate medical diagnosis, not to the word "burnout" itself. Where a page speaks of "sick leave for burnout", this always means sick leave because of the underlying, separately diagnosed illness.
