Medical Insurance Policy - Medical Policy

Please help me with the policy which you follow for the Employee Group Medical insurance. Since last year we had a huge claim on our insurance which is 224% we have got the quote from various insurance company which is 3 times double than the last year. Since the contribution what we are showing from the employee is very minimal this year we cannot go back to them asking them to pay more premium.My questions are...
1) Is there anyone who have come across this type of situation
2) How do you handle such cases? Do you ask the employee to pay the different amount or you as an employer take the complete obligation of the premium?
Awaiting a response from all the seniors.
Regards,
Maya

PMaya - In most cases, organization takes the brunt of the differential until salaries are revised. I prefer going for lower payouts (= lower premiums) if your corporate entity is agreeable and employees aren't affected.
