H.R.5573: To amend title 5, United States Code, to provide for a lump-sum payment for certain Federal employees who retire with a substantial amount of unused sick leave for which they would not otherwise receive any compensation or benefit, and for other purposes.

Entitles federal employees who satisfy age and service requirements for immediate or early retirement under the Federal Employees' Retirement System or the Foreign Service Pension System and who are separated from service or transferred to a position not subject to either of those retirement systems to a lump-sum payment for 15% of the amount of their accumulated sick leave exceeding 500 hours.

Prohibits such a payment from exceeding $10,000. Excludes hours of sick leave that are creditable in the computation of any other compensation or benefit.
