Long-term care insurance costs are on the rise, as can be seen by a recently released Genworth Insurance study. Now specifics are available on just how much some of those claims are worth to the insured and how many people rely on LTC coverage.

A new study from the American Association for Long-Term Care Insurance shows that the largest LTC claim currently open has hit $1.7 million in paid benefits. The policyholder bought her coverage at age 43 and was paying premiums of $881 per year until, three years after purchase, she filed her claim. Nearly fifteen years later, that policy is still paying benefits, and has already covered claims to the tune of $1.7 million. Premiums, it should be noted, stop when an individual begins to collect benefits.

Jesse Slome, executive director of AALTCI, said that such claims can last for years and rack up substantial balances. "Insurers paid some $6.6 billion in benefits to roughly 200,000 individuals last year," he said in a statement, adding that just over 8 million Americans currently have LTC coverage of some kind in effect.
