Cost Shifting: From Airlines to Health Care

The concept of cost-shifting is easy to understand: once upon a time, when you flew from New York to San Francisco, your fare included an edible meal. Then the fare went up. That was not cost-shifting. But when the airline took away the meal and made you buy it yourself or go hungry, the airline cost-shifted dollars you paid for your meal to its bottom line.

In health care, it's a bit more difficult to understand. If you incur a hospital bill and your payer has to pay more for the same services than another payer, part of the costs of hospitalization have been shifted to your insurer (and probably to you if you have a copayment requirement). If the government doesn't pay the full beneficiary bill, based on fancy higher-mathematical calculations (read - "guesses") to justify paying a lower amount, the government has shifted costs to your insurer and to you. If your HMO says that you have to leave the hospital on the second day after hospitalization, when you still are pretty sick and can't take care of yourself, and your family has to stay home from work to take care of you, the HMO has shifted costs from itself to you and your family and perhaps your employers. And if the uninsured in the emergency room can't pay their bills, you and your insurer and the government will have to subsidize their care. Neat, huh?

Now, let's take it a step further. If you work for a small employer and have several co-workers who have incurred high health care costs, the premium for health insurance at renewal time may go up disproportionately, making your employer look somewhere else for coverage. Not only has the initial insurer rid itself of what it considers an adverse actuarial risk, but if another insurer takes on your company, the first insurer may have moved an adverse risk to a competitor. A number of years ago, when an aggressive national HMO took on bartenders (and, if my memory is correct, grave-diggers) in one city, its competitors were joyful: they knew their insurance experience with those occupational groups was awful and were glad to get rid of them to the new competitor in town. Incidentally, the HMO eventually went into bankruptcy. Apply the same way of thinking to the decisions of hospitals to move from high-cost low-reimbursement areas (center city) to low-cost higher reimbursement areas.

So, in health care, cost shifting is a way to increase profits, move costs to someone else's pocket, disadvantage your competitor and game the system. Cost-shifting is a monetary concept, not a quality-related one.
