Kay Paggi has been the bearer of bad news more times than sh= e cares to remember.

The senior-care coordina= tor has helped hundreds of Dallas families find long-term care for f= rail parents. Almost always, they think Medicare will pick up most o= f the tab, the same as it does for hospital stays and doctor visits.= "They're shocked when I tell them that Medicare doesn't = pay for long nursing home stays," she said. "All of a sudden, = they have this look of horror as they realize their parents will hav= e to foot the bill. Those retirement nest eggs go poof."

Over 20 years, Paggi has seen many seniors spend almost th= eir last dollar on personal care at home or an assisted-living commu= nity before turning to a nursing home and ultimately relying on Medi= caid, the health care program for the poor.

&= quot;Our system of paying for long-term care in this country is broken,&quo= t; she said. "Unless you have a big family or thick wallet, you= 'll run into trouble in old age."

A= s lawmakers debate how to pay for acute care for 46 million uninsured = Americans, advocates for older or disabled adults are urging the Obama = administration and Congress to discuss long-term care's financing= problems, too.

Possible reforms range from p= roviding more federal money for home care to creating a national ins= urance pool that would protect people against long-term care expense= s.

"It doesn't make sense to figure out ho= w to pay for the hospital care of a heart attack victim but overlook= the day-to-day problems of someone living with congestive heart fai= lure," said Howard Gleckman, a senior research associate at the= Urban Institute and author of Caring for Our Parents.

Long-term care includes everything from help with bathing,= dressing and household tasks to assistance with taking medications.= It may be provided by family members or paid caregivers in the home= or at a facility like an adult day care center or nursing home. =

Ten million Americans require long-term care. But by 20= 30, 37 million boomers will be living with more than one chronic con= dition such as arthritis or diabetes, said Larry Minnix, president o= f the American Association of Homes and Services for the Aging. =

Health care and long-term care go hand in hand, experts = say.

"If the chronically ill forget to take the= ir medications or they can't get to their doctors' offices= , their health will deteriorate, and they'll wind up back in th= e hospital," said James Swan, professor of applied gerontology = at the University of North Texas.

Lawmakers won'= ;t wring savings out of the health care system without managing chro= nic illnesses effectively, and that will mean making long-term care = more accessible and affordable, he said.

Boomers coming

The nation's long-term care system is = at risk of collapsing when aging boomers need help in a decade or tw= o, experts warn.

Medicare covers short nursing home = stays and some home health care, but those services are intended mai= nly for patients recovering from illnesses or injuries. The federal = health care program isn't set up to meet the day-to-day needs o= f the chronically ill.

Nor is private insurance expe= cted to become the primary means for financing long-term care, thoug= h its role will grow. High premiums will remain a big hurdle for man= y, said Diane Rowland, executive vice president of the Kaiser Family= Foundation.

For a 60-year-old individual, annual pr= emiums for a typical policy average $2,329, according to Kaiser and = the Avalere Health consulting firm.

For a cou= ple the same age, premiums average $3,096 a year.

Mo= st long-term care is provided by unpaid family members who often make = personal sacrifices. The typical caregiver is a middle-age daughter who = must quit her job or scale back her hours to look after a parent at h= ome.

Paid care can quickly exhaust life savings. The= median cost of a private room at a Dallas nursing home is $54,750 a= year, while the median charge for an assisted-living community is $= 33,456, according to Genworth Financial.

As o= lder or disabled adults have spent their way into poverty, Medicaid = has become the anchor of long-term care and now accounts for almost half = of the $200 billion that the government, private insurers and i= ndividuals pay for such help each year.

"Medica= id was supposed to act only as a safety net for the poorest, but it = has become the single largest source of financing for long-term care= ," said Doni Van Ryswyk, manager of the North Central Texas Area = Agency on Aging.

Medicaid could stretch its dollar= s by caring for more people at home instead of in nursing homes, sai= d Elaine Ryan, vice president of government relations for AARP. =

"It would be a win-win for Medicaid and its benefic= iaries," she said.

Medicaid could care for thr= ee people with home and community-based services for what it spends = on one nursing home resident, according to the AARP Public Institute= .

"And nine of 10 older adults prefer to remain= in their homes anyway," Ryan said.

In Texas . . .

Texas has done better than other sta= tes in shifting to home and community-based programs, but many peopl= e still must wait one to two years for the care because of state bud= getary pressures, said Lue Taff, director of the elder support progr= am at the Senior Source in Dallas.

Though Texas and = other states are required by law to provide nursing home beds to eli= gible Medicaid recipients, they have the discretion to limit their h= ome and community-based services.

As part of health = care reform, advocates are pressing Congress to give states a bigger= federal match so that they can afford to expand in-home programs an= d lessen the need for more expensive nursing home care.

= The American Association of Homes and Services for the Aging, a trade = group, is also urging lawmakers to create a national insurance pool t= hat would pay for itself. Workers would contribute to the fund throu= gh payroll deductions and receive a cash benefit if they became disa= bled.

"For essentially the price of a cup of co= ffee each day, people could have an average long-term care benefit o= f $75 a day," Minnix said. "If such an insurance program w= ere in place and everyone participated, Medicaid's costs would = be cut in half."

The national pool's succe= ss would depend on how many workers participated, experts say. <= /p>

"You've got to make any such insurance pool man= datory for it to be affordable," said Joshua Wiener, director o= f aging research for the RTI International think tank. "Otherwi= se, only the people who know they'll need the coverage will buy= it, and the premiums will be too high."

Suppor= ters say workers would be automatically enrolled in the fund, though= anyone could opt out. That would spread the risk across a broad pop= ulation and keep premiums low.

Minnix said the disab= led could use the cash benefit to pay for any services they needed. = Workers who wanted additional coverage could buy private insurance. =

Past debates over long-term care have been stymied b= y disagreements over whether it should be financed with public or pr= ivate money, said Judith Feder, professor of public policy at George= town University.

"That rhetoric obscures the fa= cts," she said. "We already have a mixed public-private sy= stem, and we always will. The real choice is whether to keep today&#= x27;s dysfunctional system or create something that won't buckle = under millions of aging boomers."
