Its true, you can change plan mid-term with Laya but if there are any parts of the new plan classed as an upgrade, they will apply a
2 year waiting time for any pre-existing conditions in relation to the upgraded part of the new plan. The excess amount of 500 falls
under this rule, so it will apply to this procedure next week. If you change plan, the new excess would apply to any new conditions arising in the future.
That's why is important to ensure that the excess amount for day case etc suits when considering lower priced plans, especially if you
have ongoing health issues and pre-existing conditions.
It would be a good idea, regardless to contact Laya anyway just to confirm.
