Scope/domain statement for the code system

(Official or from HTA)

"In 1987, the state of New York passed legislation instituting a DRG-based prospective payment
system for all non-Medicare patients. The legislation included a requirement that the New York
State Department of Health (NYDH) evaluate the applicability of the DRGs to a non-Medicare
population. In particular, the legislation required that the DRGs be evaluated with respect to neonates and patients with Human Immunodeficiency Virus (HIV) infections. NYDH entered into an agreement with 3M HIS to assist with the evaluation of the need for DRG modifications as well as to make the necessary changes in the DRG definitions and software. The DRG definitions developed by NYDH and 3M HIS are referred to as the All Patient DRGs (AP DRGs). "

"The initial release of the AP DRGs consisted of the additions of Major Diagnostic Categories
(MDC) 24 and the restructuring of the newborn MDC. For the purpose of consistency with the CMS DRGs, the initial AP DRGs were
referred to as Version 5.0 and were effective in New York state beginning on January 1, 1988.
Since the initial release, the AP DRGs have been updated every one to two years"
