D.C. Mun. Regs. tit. 29, r. 29-4818
DHCF may apply an age-adjuster to claims associated with specialty hospital inpatient stays where the beneficiary's age falls outside of the age range used to calculate the base rate as is typically associated with that hospital's patient population.
In order to ensure budget predictability, monitor payments, and identify deviations from budget targets, DHCF shall make a documentation and coding adjustment (DCA) that reduces the base rate to offset case mix increases due to operational improvements in documentation and coding. DHCF, or its designee, shall evaluate the DCA every six (6) months.
Where Healthcare-Acquired Conditions (HAC) assignment impacts the relative weights of a claim, DHCF shall use the weight minus the HAC diagnosis to determine final payment to the specialty hospital.
