Managing DRGs: knowing what to cut--and when.

Area of Science:

• Health economics
• Hospital administration
• Radiology management

Background:

• Medicare is transitioning from retrospective, cost-based reimbursement to a prospective Diagnosis-Related Group (DRG) system.
• This shift presents a fundamental conflict with existing financial incentives for hospitals.

Purpose of the Study:

• To highlight the managerial challenges posed by Medicare's DRG reimbursement system during its phase-in period.
• To inform hospital administrators, particularly in radiology, about the dual reimbursement methodologies and associated cost-cutting imperatives.

Main Methods:

• Analysis of the conflicting incentives between retrospective cost-based and prospective DRG reimbursement models.
• Examination of the implications of a three-year phase-in period where both systems are active.

Main Results:

• The phase-in period creates a unique managerial challenge, requiring administrators to navigate dual reimbursement systems.
• Hospital administrators must strategically plan cost reductions applicable to both retrospective and prospective payment models.

Conclusions:

• Effective management during the Medicare DRG phase-in requires a dual focus on cost control under both old and new systems.
• Radiology and hospital administrators need to understand the timing and scope of cost-cutting measures for successful adaptation to DRG reimbursement.
