One legislative policy option for controlling postacute care costs is
for Medicare to make a ''bundled'' payment to hospitals to cover episo
de costs: acute plus postacute care costs. But a bundled payment might
not match the costs of treatment as well as payment now does under Me
dicare's prospective payment system (PPS). Simulating hospital margins
with and without postacute care costs, this paper finds that risks to
the typical hospital would not. increase under postacute care bundlin
g. A central characteristic of a bundled payment is that it would cove
r multiple providers. From this characteristic comes bundled payment's
major strength: cost containment.
