CAMDEN, Ala. — Hundreds of hospice providers across the country are facing the catastrophic financial consequence of what would otherwise seem a positive development: their patients are living longer than expected.

Over the last eight years, the refusal of patients to die according to actuarial schedules has led the federal government to demand that hospices exceeding reimbursement limits repay hundreds of millions of dollars to Medicare.

The charges are assessed retrospectively, so in most cases the money has long since been spent on salaries, medicine and supplies. After absorbing huge assessments for several years, often by borrowing at high rates, a number of hospice providers are bracing for a new round that they fear may shut their doors.

One is Hometown Hospice, which has been providing care here since 2003 to some of the most destitute residents of Wilcox County, the poorest place in Alabama.
