Section 9105 of the Consolidated Omnibus Budget Reconciliation Act of 1985 (Public Law 99-272) amended Section 1886(d)(5) of the Social Security Act (the Act) to add new subparagraph (F), known as the Medicare Disproportionate Share Hospital (DSH) adjustment provision, which became effective for discharges occurring on or after May 1, 1986.
Methods to Qualify for Medicare Disproportionate Share Hospital Adjustment
A hospital can qualify for the Medicare DSH adjustment by using one of the following two methods:
The primary method for qualifying for the Medicare DSH adjustment pertains to hospitals that serve a significantly disproportionate number of low-income patients and is based on the disproportionate patient percentage (DPP), which is equal to the sum of the percentage of Medicare inpatient days (including Medicare Advantage inpatient days) attributable to patients entitled to both Medicare Part A and Supplemental Security Income (SSI) and the percentage of total patient days attributable to patients eligible for Medicaid but not eligible for Medicare Part A. If a hospital’s DPP equals or exceeds a specified threshold amount, the hospital qualifies for the Medicare DSH adjustment. The Medicare DSH adjustment is determined by using a complex formula (the applicable formula is also based on a hospital’s particular DPP).
Alternate Special Exemption Method
The alternate special exemption method for qualifying for the Medicare DSH adjustment applies to hospitals that are located in an urban area, have 100 or more beds, and can demonstrate that more than 30 percent of their total net inpatient care revenues come from State and local government sources for indigent care (other than Medicare or Medicaid). These hospitals are also known as “Pickle” hospitals as defined under Section 1886(d)(5)(F)(i)(II) of the Act. If a hospital qualifies under this method, the statute provides for a specific Medicare DSH adjustment.
