To request a reassessment, complete the Request a WIA benefit reassessment form ('Aanvragen herbeoordeling WIA door (ex-) werkgever, verzekeraar of andere gemachtigde organisatie’). You will need to log in to the employer portal with your eHerkenning account to do this.

We will need any available medical information. Also, it is important you tell us the reason for your request. Please cover the following points:

• the date on which you found about the changes in health
• the specific changes in their health (without providing medical information)
• the previous assessment of the physician (‘verzekeringsarts’) about whether the situation is likely to improve
• the opinion of the physician about how likely it is that the employee or former will be able to return to work
• the consequences of the changes in health, in your opinion

Please also keep the following details close to hand:

• your employee’s or former employee’s name and citizen service number (‘BSN’)
• your payroll tax number (‘loonheffingennummer’)

Please note: Medical information may only be sent by post by a physician or the occupational health and safety service (‘arbodienst’) to the address specified on the form. This must be done no later than 1 day after you request a WIA benefit reassessment. The envelope should be marked as ‘private and confidential’ by writing ‘Medisch geheim WIA benefit reassessment’ on it.

We will decide if a WIA benefit reassessment is needed depending on the information we receive. If we think the changes in health will affect your employee’s or former employee’s ability to work, they will be reassessed. We base our decision on existing information, call your employee or former employee or invite them to an appointment.

After the reassessment, your employee or former employee will receive a decision within 8 weeks. You will receive a copy of this letter.
