(e) Specialty long term acute care hospital.
(3) For dates of service occurring on or after April 1, 2020 through December 31, 2020, and each calendar year thereafter, an upper payment limit (UPL) payment per diem shall be added to the specialty long term acute care hospital rates (hereinafter add-ons).

Such add-ons shall be calculated for each hospital by dividing the hospital’s latest approved UPL demonstration payment, by its Medicaid fee-for-service specialty hospital days, as reported in its most recently submitted institutional cost report. Each hospital’s rate add-on shall be subject to and contingent upon the terms of a binding memorandum of understanding executed between the Department of Health and the public general hospital or public health system receiving an add-on, and shall be subject to termination or adjustment based on the terms of that agreement. The total amount paid for the add-on shall be included in the applicable annual UPL demonstration. If the annual UPL demonstration yields an amount that is more or less than the aggregate amount paid for the add-on, the add-on shall be adjusted to reflect the demonstration amount.

(g) Substance abuse detoxification inpatient services.
For patients discharged on and after December 1, 2008, rates of payment for general hospitals which are certified by the Office of Alcoholism and Substance Abuse Services (OASAS) to provide services to patients determined to be in the diagnostic category of substance abuse (MDC 20, DRGs 743 through 751) will be made on a per diem basis. This includes inpatient detoxification, withdrawal, and observation services. Medically managed detoxification services are for patients who are acutely ill from alcohol and/or substance related addictions or dependence, including the need or risk for the need of medical management of severe withdrawal, and/or are at risk of acute physical or psychiatric co-morbid conditions. Medically supervised withdrawal services are for patients at a mild or moderate level of withdrawal, or are at risk for such, as well as patients with sub-acute physical or psychiatric complications related to alcohol and/or substance related dependence, are intoxicated, or have mild withdrawal with a situational crisis, or are unable to abstain yet have no past withdrawal complications. The per diem rates for inpatient detoxification, withdrawal, and observation services will be determined as follows:
(1) The operating cost component of the per diem rates will be computed using 2006 costs and statistics, excluding physician costs, as reported to the department by general hospitals prior to 2008, adjusted for inflation. The inflation factor will be calculated in accordance with the trend factor methodology described in this Subpart. The average operating cost per diem for the region in which the hospital is located will be calculated using costs incurred for patients requiring detoxification services. The operating cost component of the per diem rates will be transitioned to 2006 as follows:
(2) For purposes of establishing the average operating cost per diem by region for medically managed detoxification and medically supervised withdrawal services, the regions of the state are defined as follows:
(j) Rates of payment for inpatient services described in subdivisions (a) and (b) of this section which utilize regional averages for determining a cost ceiling shall utilize regions of the State set forth in section 2807-c(4)(l)(iii)(E) of the Public Health Law and this subdivision, except that if the otherwise applicable region has less than five exempt hospitals or units in the service, facilities located in the nearest regions will be used to establish a minimum of five hospital or units for the purpose of determining ceilings. Such regions are as follows:
(k) Capital cost components of per diem rates determined pursuant to this section shall be computed on the basis of budgeted capital costs allocated to the exempt hospital or distinct unit of a hospital pursuant to the provisions of section 86-1.25 of this Subpart divided by exempt hospital or unit patient days reconciled to actual total expense.
(l) New hospitals and new hospital units.
The operating cost component of rates of payment for new hospitals, or hospital units, without adequate cost experience shall be computed based on either budgeted cost projections, subsequently reconciled to actual reported cost data, or the regional ceiling calculated in accordance with subdivision (i) of this section, whichever is lower. The capital cost component of such rates shall be calculated in accordance with section 86-1.25 of this Subpart.
