I recently read an article on MSN that health care after retirement is costing close to ~250k despite medicare and is growing at at brisk pace of 6-7.5% a year.

How do i plan for this in my retirement plan ? This kind of expenses will erode my retirement savings by a lot.

Keep working and saving.

The courts have ruled that you are on your own. Companies that offer health care in retirement are not required to do so and may drop the plans at any time.
