(Bloomberg) — Four of five U.S. companies have raised deductibles or are considering doing so as health costs increase, according to a survey of more than 700 employers.

About one-third of the companies have already increased deductibles or other cost-sharing provisions like copays, and 48% are considering similar moves, the survey by New York- based consulting firm Mercer LLC found.

Employers are looking for ways to trim expenses as health- care costs continue to rise and the Patient Protection and Affordable Care Act increases required benefits and imposes new taxes. United Parcel Service Inc. dropped coverage for employed spouses and Home Depot Inc. sent 20,000 part-time workers to government-sponsored insurance websites.

“Employers with a lot of part-time workers and low-wage employees are going to bump against the coverage requirements for anyone working 30 or more hours,” Beth Umland, Mercer’s director of research for health and benefits, said in a telephone interview. “Employers who already offered generous packages, who don’t have a lot of part-timers, are worried about the excise tax.”


Cadillac tax

The excise tax, known as the “Cadillac” tax, is a provision of the Affordable Care Act aimed at businesses with generous health benefits. Employers with coverage exceeding $10,200 for individuals and $27,500 for families will be taxed 40% starting in 2018, on the theory that the plans boost medical costs.

About 62% of employers surveyed had concerns related to the so-called Cadillac tax. According to Mercer, 42% of employers would be subject to the tax in 2018 if they made no changes to their current plans.

Employers aren’t waiting to make changes, the survey found. Almost one in five employers have already dropped the plans and another 33% are considering dropping the coverage. Employers are turning instead to private exchanges, or consumer- directed health plans, which give employees personal health-care accounts.

About 8% of employers have, like UPS, dropped coverage for spouses who have other coverage available, and another 11% are considering doing so for 2015, the survey said.
