I've got my Policy document here and of course it's so confusingly written, it's barely understandable by most people, but it states:
Excess is paid for each INCIDENT for each PERIOD OF INSURANCE. In their glossary of how they term these words, they state:
INCIDENT - A specifically identifiable illness in your pet's normal healthy state. Incidents which are reoccurring and ongoing are considered to be one loss (regardless of the number of incidents or areas of the body affected) and are defined as:
injury, illness or disease or change in your pet's normal healthy state, which are incurable and likely to continue for the remainder of your pet's life.
Reading that above, Odie has an ILLNESS, which is INCURABLE and WILL continue for the rest of his life so it therefore considered to be one loss (as stated in their explanation of INCIDENT).
Hubby is going to look at it when he gets home from work but I'm sure Elaine.e said she only had to pay the excess once as it was an ongoing claim. Thanks guys.
