  Jul. 11--Eighty percent off sounds like a great deal. But if the  starting  price is high enough, even 20 percent can be too much to part  with. Alfred  Smith of Zebulon doesn't have much choice.  
  Smith, 57, suffers from kidney failure. He's on the transplant  list at  Duke University Health System, and he hopes to have his  worn-out organs  replaced with a healthy donated kidney as soon as one  becomes available.  
  Because he is disabled, Smith qualifies for Medicare, which will  pay for  80 percent of the $100,000 operation. It's never clear  exactly how much the  patient will owe because of the complexities of  medical billing and coverage,  but Smith figures he should be prepared  to be responsible for as much as  $20,000.  
  It's an amount that Smith says he isn't even close to  being able to pay.  He was forced to quit his job as a wastewater  treatment operator at a  Knightdale manufacturing plant three years ago  when he began dialysis  treatments.  
  The surgery would take place regardless, but Smith is trying pull  together at least some of the money by asking for donations. He's  got some  time to work on it. Smith said he likely will have to wait at  least two more  years before a kidney becomes available from an  anonymous donor. The  transplant would come sooner if a living donor  volunteers to give him a  kidney.  
  'There is no way I can do this on my own,' said Smith,  who gets by on  monthly disability benefits of just over $1,300.  'I'm living paycheck to  paycheck.'  
  Smith's case is an extreme one.  
  But paying medical bills is a struggle for millions of Americans --   including people who have health coverage through Medicare or private   insurance. And it's probably going to get worse as health-care  costs soar and  budget-conscious employers shift more of the financial  responsibility to  workers.  
  About 20 million U.S. families had problems paying medical bills in  2003,  according to a national survey of 25,400 families recently  released by the  Center for Studying Health System Change. More than  two-thirds of families  that said they struggled had health insurance.  
  The center didn't indicate the survey's margin of  sampling error. Nor did  the survey define what it means to have  difficulty paying medical bills.  
  But families reported situations such as being contacted by  collection  agencies, postponing a major household purchase such as a  car or borrowing  money to pay health-care bills. Consumers also said  they had to forgo doctor's  visits or leave prescriptions unfilled  because they had no money to pay or  feared racking up additional  medical bills.  
  A similar survey of 4,052 people released in March by the  Commonwealth  Fund found that 71 million working-age adults had trouble  paying medical  bills. This survey also did not define  'trouble,' and it did not report its  margin of sampling  error.  
  But it found that 44 percent of people who said they struggled used  all  or most of their savings to pay medical bills, and 20 percent  incurred large  credit-card debt or had to take a loan against their  home to cover health  expenses. Just over a fourth of people who had  problems paying said they had  been unable to pay for basic necessities  such as food, heat or rent because of  medical bills.  
  Smith says he already spends a good chunk of his income on medical  care.  About $300 a month goes to pay for medicine alone. Smith takes  pills for high  blood pressure and diabetes, a disease that contributes  to his kidney  problems.  
  The Raleigh dialysis clinic that treats him accepts Medicare's   reimbursement as payment in full, so Smith doesn't face  out-of-pocket expenses  for the four-hour treatments he must have three  times a week. Dialysis flushes  waste materials from his bloodstream --  normally the kidneys' job.  
  Smith recently learned he might qualify for a discount program Duke   established in January for people with limited incomes. Based on  Smith's  annual income, the Duke program could waive its right to  collect any of the  cost of the transplant from him. Smith plans to show  the health system proof  of his income by submitting a copy of his  disability check stub and other  financial documents to see whether he  qualifies.  
  But Smith still fears he won't be able to pay for  anti-rejection medicine  after his surgery. He hopes people will be  willing to donate money to help him  pay for the $300-a-month drugs,  which he will have to take for the rest of his  life. Smith has siblings  in Zebulon but said they aren't in a position to help  financially.  
  So Smith set up an account at a Centura bank branch to receive  donations,  an idea he got after checking out a few organizations for  kidney patients.  Then he prepared fliers explaining his plight,  requesting that donations be  mailed directly to the bank. So far, his  church has donated $100.  
  'I've worked in sales, so I'm not shy about asking  people for money,'  said Smith, who sold cars for a time after  leaving his wastewater treatment  job. Ultimately, he said it became  clear that working was too hard on his  health.  
  Medical inflation and a trend toward higher out-of-pocket costs for   consumers are making it harder for all patients to keep up with medical  bills.  Costs for physician and hospital care, medical technology and  medicines have  been rising by 10 percent or more for at least the past  four years and show  few signs of slowing.  
  Medicare members such as Smith are particularly exposed because  there is  no cap on what they can be asked to pay out of pocket, unlike  most private  insurance plans. The lack of a limit on out-of-pocket  costs is considered by  health insurance experts to be one of the most  serious flaws in the federal  insurance program.  
  Employers, who pay for most private health insurance, have been  sharing  the pain by increasing deductibles, co-payments and other  out-of-pocket costs.  
  'For many people, maybe those increases do not take a big  bite, but if  you need a lot of health care, it adds up fast,' said  Peter Cunningham, a  senior health researcher at the Center for Studying  Health System Change and  co-author of the medical debt study.  
  According to the survey, about 23 percent of families with  out-of-pocket  expenses of between $801 and $2,000 said they had trouble  paying those bills.  And when such costs were more than $2,000 a year,  nearly 35 percent of people  said they had difficulty paying.  
  Most industry watchers expect out-of-pocket costs to continue  rising.  Employers still see passing costs on to workers as the best way  to trim  soaring increases in health insurance costs, said Steve  Graybill, a senior  health-care consultant in the Charlotte offices of  Mercer Human Resources  Consulting.  
  People who buy their own health insurance are gravitating to   higher-deductible plans to save on premiums. That means more money out  of  consumers' pockets before coverage kicks in.  
  'What's happening here is that everything is pushing more  responsibility  to the consumer,' Graybill said. 'It's a  hard message.'  
  PAYMENT TIPS  
  KNOW YOUR COVERAGE: Review the summary of benefits that describes  exactly  what is covered by private health insurance. This can be a good  starting point  to determine eligible care and out-of-pocket expenses.  Many health plans also  make summaries of benefits available on their  Internet sites.  
  ASK ABOUT HELP: Most hospitals and doctor's offices have  professionals on  staff to route patients with limited income into  programs that may pay for  their health care, see whether they qualify  for charity care or get them a  discounted price. To qualify for such  programs, patients usually must submit  proof of their income, including  copies of check stubs and tax documents.  Getting signed up before  treatment can reduce a qualified patient's risk of  racking up  debt.  
  CHECK FOR ERRORS: Patients can ask for itemized medical bills.  After  expensive or complex medical care, check billing statements for  double billing  or charges for care that was not delivered.  
  SET UP AND USE AN INSTALLMENT PLAN: Most health-care providers say  they  allow patients to pay large balances over time. Usually, if  patients make a  reasonable effort to pay, providers will not send them  to collections. Failing  to pay medical bills can result in a blemish on  your credit report.  
  USE OTHER PROGRAMS: If your company offers flexible spending  accounts,  you can use one to reduce taxes by setting aside pretax  income for many  health-care expenses. If you can afford supplemental  insurance to cover  out-of-pocket medical expenses, think about buying  it, especially if you  expect to need care.
