55. DRGs??
56. Definitions Manual The DRGs were therefore developed as a patient classification scheme consisting of classed of patients who were similar clinically and in terms of their consumption of hospital resources.
57. Pre-MDC Heart, Liver, bone marrow, lung transplants are very resource intensive and can be performed for diagnoses in many different MDCs.
Tracheostomies are performed primarily for patients on long term ventilator support and therefore such patients are very resource intensive.
58. Pre-MDC Transplantation
Heart ( DRG10301~10302 )
Liver ( DRG48001~48002 )
Lung ( DRG49501~49502 )
Bone marrow ( DRG48101~48102 )
??? Kidney transplant
Tracheostomy (DRG 48201~48302)
59. Formation of the DRG-1 The process of forming the DRGs was begun by dividing all possible principal diagnoses into 23 mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories(MDCs).
Two new MDCs (24&25)were created in the eighth version of the DRGs. (HCFA-8,1991)
60. Formation of the DRG-2 Principal diagnosis linked to anatomical system (MDCs).
Patient’s surgical status Principal diagnosis (nonsurgical DRG) or
Extent of surgical procedure (surgical DRG)
Comorbidities/Complications, Age, Discharge status
61. Complications & Comorbidities;CC-1 A complications is a condition which did not exist prior to the admission
A comorbidities is a condition which existed prior to the admission
A significant complications or comorbidities (CC) is a secondary diagnosis which would be expected to extend the patient’s length of stay by at least one day in at least 75 percent of patient’s.
