Poland’s electronic sick leave system (e-ZLA) contains codes revealing crucial health information impacting benefit amounts and duration, despite protecting diagnoses.
What Do the Codes on Sick Leave Indicate?
Electronic sick leave (e-ZLA) contains more information than initially apparent. While employers don’t see the diagnosis, specific letter and number codes convey important data about the employee’s health situation and affect the amount and length of the benefit paid.
The meaning of these codes can have real financial consequences.
Decoding the Letter Codes on Medical Certificates
Letter codes on sick leave indicate specific circumstances of the illness, directly impacting the length of the benefit period or the amount of benefits paid.
Can a Patient Request Code Removal? What are the Consequences?
Patients can request that codes B and D not be entered by their doctor. However, this decision carries financial consequences: omitting code B may result in a benefit payment of 80% instead of 100% (until a pregnancy certificate is provided), and omitting code D will shorten the maximum benefit period to 182 days.
What Do the Numbers 1 and 2 Mean on Sick Leave?
The numbers 1 and 2 on sick leave (e-ZLA) indicate medical recommendations determining the level of activity the patient can undertake during recovery. “1” indicates no activity, while “2” allows limited activity.
Even with a “2” designation, activities should not negatively impact the recovery process, and the attending physician always provides specific instructions regarding permissible activities. These designations are important for the employer and ZUS during any control of the proper use of sick leave.
Information Visible to the Employer: Key Details
Employers do not see the specific diagnosis of the illness on the sick leave. The e-ZLA document sent to the employer is designed to protect employee privacy and does not reveal the nature of the illness.
The sick leave contains only the information necessary for proper benefit calculation and to verify that the employee is using their time off in accordance with the doctor’s recommendations.
When is a 270-Day Sick Leave Entitlement Available?
A sick leave benefit is available for 270 days (instead of the standard 182 days) in two specific situations.
If a patient with tuberculosis requests that code D not be entered on the sick leave, their entitlement to sick leave benefits will be limited to the standard 182 days. Correct designation on the e-ZLA is therefore essential to be able to benefit from the full, extended period.
Sick Leave Codes: A Summary
Codes on sick leave play a key role in the sickness benefit system: they determine the amount of the benefit, the length of its payment, and the method of employee control. While patient privacy is protected and the employer does not know the diagnosis, letter and number designations can reveal a lot about the circumstances of the illness. Their absence or change may mean financial losses or a shortening of the support period.
