- Legacy Systems
Computer applications, both hardware and software, which have been inherited through previous acquisition and installation.

- Limiting Charge
The maximum amount that a non-participating physician is permitted to charge a Medicare beneficiary for a particularly defined procedure or bundled service. These limits are published by the individual state intermediaries for Medicare and HCFA and are usually combined in reports with the allowed charges and regional payment schedules. In 1993, the limiting charge was set at 115 percent of the Medicare-allowed charge. However, this does not reflect what the physician will be paid.
- Local Access Transport Area (LATA)
A defined region in which a telephone and long distance carrier operates. Important concept for those CHINs that depend upon phone lines. When creating communications networks, you try to avoid crossing boundaries of these, if possible, since costs escalate dramatically when there is a need to communicate over more than one LATA.
- Local Exchange Carrier (LEC)
The telephone company that provides and supports the local connection to the public switched telephone network. In many areas of the US, the LEC is one of the seven Regional Bell Operating Companies (RBOCs) or “Baby Bells.” These LECs become partners for organizations seeking to develop a CHIN or, more conservatively, simply seeking to integrate their information system across many sites within a region.

Ambulatory services such home health care, which can also be provided on a long-term basis, are seen as alternatives to long-term institutional care.
- Long Term Care Insurance
Insurance designed to pay for some or all of the costs of long term care.
