To figure out how much money your hospital got paid for your hospitalization, you must multiply your DRG’s relative weight by your hospital’s base payment rate. Here’s an example with a hospital that has a base payment rate of $6,000 when your DRG’s relative weight is 1.3: $6,000 X 1.3 = $7,800.

What are the pros and cons of a DRG payor system?

The advantages of the DRG payment system are reflected in the increased efficiency and transparency and reduced average length of stay. The disadvantage of DRG is creating financial incentives toward earlier hospital discharges. Occasionally, such polices are not in full accordance with the clinical benefit priorities.

Who assigns the DRG for a claim?

Over 14,000 ICD-10-CM diagnosis codes are designed by CMS as CCs and about 3,200 codes are MCCs. Every year, CMS assigns a “relative weight” to every DRG. The relative weight determines the reimbursement associated with that DRG and reflects the patient’s severity of illness and cost of care during hospitalization.
