How many days is an L4 issued – rules, limits, and exceptions

L4 is a common term for a medical leave certificate that confirms temporary incapacity for work and serves as the basis for the payment of sickness benefits. The number of days for which L4 is issued depends on the patient’s health condition, the nature of the illness, and legal regulations, and its duration is assessed individually by the doctor each time.

• The length of L4 depends on the medically justified incapacity for work.
• There is an annual limit on receiving sickness benefits.
• Different rules apply to pregnant women and those suffering from tuberculosis.
• After exhausting the limit, further forms of support may be available.

What is a medical leave (L4) and what is its purpose?

A medical leave (L4) is a document issued by a doctor that confirms temporary incapacity for work due to illness or another health condition. Its purpose is to allow the patient to recover without the need to perform professional duties.

The basis for issuing L4 is a medical assessment, not the patient’s expectations. Occupational medicine studies show that proper use of medical leaves reduces the risk of complications and shortens the overall treatment time.

L4 also has legal and financial significance, as it conditions the payment of sickness remuneration or benefits.

For how many days can a doctor issue L4 at once?

A doctor can issue L4 for any number of days if it is justified by the patient’s health condition. There is no strict limit on the length of a single leave; however, in practice, it is often issued for shorter periods with the possibility of extension.

Clinical studies indicate that a gradual assessment of the patient’s health allows for better matching of the leave duration to the actual incapacity for work. Therefore, doctors often monitor the course of the illness and decide on further L4 at the next visit.

The length of the leave must always correspond to the actual health needs.

What is the maximum period for being on L4?

The total maximum period for receiving sickness benefits is 182 days within one sickness year. This means that the sum of all days of leave for the same or different reasons cannot exceed this limit.

Exceptions are pregnancy and tuberculosis, where this limit extends to 270 days. Epidemiological studies confirm that a longer recovery time in these cases is significant for the patient’s health and public safety.

After exceeding the limit of 182 or 270 days, the standard sickness benefit is no longer available.

Who pays benefits during L4?

In the initial period of leave, the benefit is paid by the employer in the form of sickness remuneration. This rule applies for the first 33 days of incapacity for work in the calendar year, and for individuals over 50 years of age, for 14 days.

After this period, the payment is taken over by the Social Insurance Institution, which administers the sickness benefit. Research on social insurance systems indicates that this division limits abuses and stabilizes the financial system.

The patient does not need to submit separate applications, as e-ZLA is automatically sent to the system.

Can L4 be issued retroactively?

Issuing L4 retroactively is possible, but only in strictly defined situations. A doctor can backdate the leave for a maximum of 3 days if there are justified medical grounds for it.

Legal-medical studies emphasize that issuing retroactive leaves is exceptional and subject to special scrutiny. The doctor must be able to demonstrate that the patient was incapable of work during that period.

Abusing this possibility may result in legal consequences.

What happens after the full limit of L4 is used up?

After exhausting the maximum period for receiving sickness benefits, the patient can apply for rehabilitation benefits. This is granted if further treatment or rehabilitation is expected to restore the ability to work.

Research in medical rehabilitation indicates that this form of support allows many patients to return to professional activity without having to go on disability. This benefit is granted for a specified period after a medical assessment.

It is not an automatic extension of L4 and requires a separate procedure.

How does termination of employment affect L4?

Termination of employment does not always mean losing the right to sickness benefits. If the incapacity for work arose while the contract was still in effect, the patient retains the right to benefits.

Systemic studies show that this solution protects individuals who lost their job during illness from sudden lack of means of subsistence. In such cases, the benefit is paid directly by ZUS.

The condition is meeting the insurance criteria.

Q&A section

Can a doctor issue L4 for several months at once?
Yes, if the patient’s health condition justifies it, although often the leave is extended in stages.

Does the 182 days reset every calendar year?
No, it counts as a so-called sickness year, not a calendar year.

Do I have to return to work after using L4?
No, it does not.sze – it is possible to receive rehabilitation benefits or other forms of further treatment.
