    • The direct billing system
    • The submission and processing of claims
    • The Cigna and ESO contact persons


Forms in PDF format can be read and printed using the free software Acrobat Reader The insured can fill out the forms in the language of their preference and return them by fax or mail.

Electronic medical claims

Cigna offers the possibility of submitting medical claims electronically, as well. To do this you will need to scan your medical bills at home. Again, details are to be found on the Cigna website.

If you have any problems in understanding the benefits or with your medical claims, you should first try to clarify this with Vanbreda directly (contact details on their website) or, failing that, with the ESO Human Resources Department.

A provider search

The insured can look for various types of medical providers around the world, using Vanbreda's international provider database.

To access the personalized section (restricted access for registered users only) a beneficiary has to enter his/her personal Cigna number, preceded by the figure 035 (035 being the identification of the ESO Plan). Example: a beneficiary with Cigna number 03382 should enter the figure 03503382.

Then, one has to enter his/her date of birth, using following format (incl. the slashes between the figures): dd/mm/yyyy.
Example: date of birth 5 January 1945 has to be entered as 05/01/1945.

If correct data are supplied and you do not get access, please contact Cignaa for further assistance.
