What factors influence DRG assignment and reimbursement?

The patient's principal diagnosis and up to 24 secondary diagnoses, including any comorbidities or complications, determine the DRG assignment. Up to 25 procedures furnished during the stay can affect the DRG. Other factors influencing DRG assignment include a patient's gender, age, or discharge status disposition.

Also question is, what directly influences the assignment of DRGs?

One MS-DRG is assigned to each inpatient stay. The MS-DRGs are assigned using the principal diagnosis and additional diagnoses, the principal procedure and additional procedures, sex and discharge status. Diagnoses and procedures assigned by using ICD-9-CM codes determine the MS-DRG assignment.

Secondly, how has DRG changed hospital reimbursement? A diagnosis-related group (DRG) is a patient classification system that standardizes prospective payment to hospitals and encourages cost containment initiatives. In general, a DRG payment covers all charges associated with an inpatient stay from the time of admission to discharge.

Beside this, what affects DRG assignment?

When an OR procedure is performed, a surgical DRG is assigned. CCs and MCCs are secondary diagnoses that may impact the DRG assignment (see examples in Table). In most cases, a CC increases the relative weight and an MCC results in an even higher weight that impacts severity and reimbursement.

How is DRG reimbursement calculated?

Calculating DRG payments involves a formula that accounts for the adjustments discussed in the previous section. The DRG weight is multiplied by a “standardized amount,” a figure representing the average price per case for all Medicare cases during the year.

What are some advantages and disadvantages of DRGs?

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.

What is the difference between DRG and APC?

APCs are similar to DRGs. Both APCs and DRGs cover only the hospital fees, and not the professional fees, associated with a hospital outpatient visit or inpatient stay. DRGs have 497 groups, and APCs have 346 groups. Payments for both are based on a weight for each DRG/APC and a rate for the facility.
