What is a "Pickle" hospital, and is it true that the "greater than 11.75% DSH Adjustment percentage" requirement is waived for them?

The 11.75% requirement is waived for a few hospitals known as "Pickle" hospitals (named for a J.J. Pickle, a former member of Congress). They are defined in Section 1886(d)(5)(F)(i)(II) of the Social Security Act as "a hospital that serves a significantly disproportionate number of low income patients and is located in an urban area, has 100 or more beds, and can demonstrate that its net inpatient care revenues (excluding any of such revenues attributable to this title or State plans approved under title XIX) during the cost reporting period in which the discharges occur, for indigent care from state and local government sources exceed 30 percent of its total of such net inpatient care revenues during the period.”
