As Health Costs Soar, G.O.P. and Insurers Differ on Cause

By ROBERT PEAR

MANCHESTER, N.H. — Workers at a circuit-board factory here just saw their health insurance premiums rise 20 percent. At Buddy Zaremba’s print shop nearby, the increase was 37 percent. And for engineers at the Woodland Design Group, they rose 43 percent.

The new federal health care law may eventually “bend the cost curve” downward, as proponents argue. But for now, at many workplaces here, the rising cost of health care is prompting insurance premiums to skyrocket while coverage is shrinking.

As Congress continues to debate the new health care law, health insurance costs are still rising, particularly for small businesses. Republicans are seizing on the trend as evidence that the new law includes expensive features that are driving up premiums. But the insurance industry says premiums are rising primarily because of the underlying cost of care and a growing demand for it.
