Illness during a business trip
(§ 12 Bundesreisekostenrecht - German regulations for travel expenses)
If business travellers become ill and are admitted to hospital, the necessary expenditure for accommodation at the business location is reimbursed for each full calendar day of the stay at hospital. No daily or overnight allowances will be paid for each full calendar day of the stay at hospital. In the event of a life-threatening condition, travel expenses for one person for one trip only - as a visitor - will be reimbursed.
Illness times at the business location without a hospital stay count towards the duration of the business trip.
