A health insurer does not always cover the full treatment. Sometimes you have to judge whether this (partial) rejection is valid.
'To health insurer', 'To patient' and 'Rejected'
These are the three columns that we split the declaration's total amount over.
The share that the health insurer will cover can be seen under 'To health insurer' and the share that is not insured will end up under 'To patient'. With declarations that require an action there will always be an amount under 'Rejected'. You will have to judge whether this rejection is valid and how to continue: should it be invoiced to the customer or should it be submitted to the health insurer again, possibly with a correction. Of course you could also choose to not charge the rejected amount at all.
Why is the declaration rejected?
Health insurers use return codes to elaborate on their acceptance or rejection. If a declaration is (partially) rejected you can hover over the return code of each treatment to see their reasoning.
If the return code's reason is unclear or if you think this might be wrong, you can contact the relevant health insurer to ask for more elaboration.
