Who can issue a medical certificate – rules, rights, and limitations

Who can issue a medical leave certificate is an important question for patients, employers, and the social insurance system because e-ZLA confirms temporary incapacity for work and serves as the basis for benefit payments. The certificate can only be issued by a doctor after conducting an examination and meeting formal requirements, and its correctness is subject to control.

• The certificate is issued by a doctor after assessing incapacity for work
• The electronic form e-ZLA is the standard in Poland
• The doctor’s authorization stems from regulations and access to the ZUS system
• Teleconsultation can be a basis for the certificate, but not in every situation

What is a medical leave certificate (e-ZLA) and what is its purpose?

Medical leave certificate (e-ZLA) is an electronic document confirming temporary incapacity for work due to health reasons. Its purpose is to protect the patient’s health and provide a basis for sickness benefit payments.

E-ZLA is transmitted automatically to the insurance system, which shortens the document circulation and reduces formal errors. Research on healthcare digitization shows that electronic leave certificates increase transparency and effectiveness of supervision.

The document has the same legal power as the former paper certificate.

Who is authorized to issue e-ZLA?

A medical leave certificate can only be issued by a doctor licensed to practice and authorized to issue e-ZLA in the system. This authorization does not depend on specialization but on meeting formal requirements and conducting an examination.

E-ZLA can be issued by, among others:

• Primary care physician
• Specialist doctor
• Dentist
• Hospital doctor

Research in professional responsibility emphasizes that every doctor bears full responsibility for the justification of incapacity for work, regardless of the place of service.

What role does the medical examination play?

A medical examination is a necessary condition for issuing a certificate. It can take the form of an in-person visit or—in certain situations—a teleconsultation.

The purpose of the examination is an objective assessment of health status and determination of whether the patient is temporarily unable to perform work. Clinical studies indicate that a properly conducted interview and symptom assessment are key for the safety of the patient and the benefits system.

Lack of medical grounds requires the doctor to refuse issuance of e-ZLA.

Is teleconsultation sufficient to issue a certificate?

Teleconsultation may form the basis for issuing a medical leave certificate if the doctor considers that remote assessment is sufficient. This typically applies to common infections, exacerbations of chronic diseases, or mental health issues.

Research on telemedicine shows that in such cases, the accuracy of medical decisions is comparable to an in-person visit. However, if symptoms require a physical examination, the doctor should refer the patient for an in-person visit.

Therefore, teleconsultation is not a universal solution.

What role does the Social Insurance Institution (ZUS) play?

The Social Insurance Institution is responsible for receiving, processing, and controlling medical leave certificates. E-ZLA is sent automatically to ZUS, enabling ongoing verification of benefit legitimacy.

System studies indicate that electronic supervision limits abuse and accelerates benefit payments. ZUS has the right to control both doctors issuing certificates and the individuals using them.

ZUS’s role is crucial for the stability of the social insurance system.

Can a dentist and pediatrician issue a certificate?

A dentist has the right to issue a medical leave certificate if the patient’s health condition justifies temporary incapacity for work. This includes acute inflammatory states or complications after procedures.

A pediatrician can issue e-ZLA both to a child and for child care reasons to a parent or guardian. Research in family medicine confirms that proper use of care certificates is significant for child health.

The scope of authorization comes from regulations, not narrow specialization.

Does the certificate always have to be electronic?

The electronic form e-ZLA is the standard used in the vast majority of cases. It allows rapid transmission of information to the employer and ZUS without patient involvement.

Research on e-health effectiveness shows that the electronic form reduces errors and delays. Exceptions are very rare and concern specific technical situations.

For the patient, this means no need to deliver documents.
