# FAQ: How Are Drgs 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.

## How are DRGs or MS DRGs developed and calculated?

The formula used to calculate payment for a specific case multiplies an individual hospital’s payment rate per case by the weight of the DRG to which the case is assigned. In a small number of MS-DRGs, classification is also based on the age, sex, and discharge status of the patient.

## How CMS calculate DRG weights?

## What is the basic formula for calculating each MS-DRG hospital payment?

MS-DRG-based Payments MS-DRG PAYMENT = RELATIVE WEIGHT × HOSPITAL RATE.

## How is hospital base rate calculated?

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.

## How do you calculate case mix index for MS DRG?

Case mix index is calculated by adding up the relative Medicare Severity Diagnosis Related Group (MS-DRG) weight for each discharge, and dividing that by the total number of Medicare and Medicaid discharges in a given month and year.

## Does length of stay affect MS DRG reimbursement?

Prolonged length of stays can devastate reimbursement, making strong clinical documentation a must.

## Will Medicare pay for transfer from one hospital to another?

Normally, Medicare pays a hospital discharging a beneficiary the full amount for the corresponding diagnosis-related group (DRG). In contrast, a hospital that transfers a beneficiary to another facility or to home health services is paid a graduated per diem rate, not to exceed the full DRG payment.

## How does the DRG payment system work?

In 1987, the DRG system split to become the All-Patient DRG (AP-DRG) system which incorporates billing for non-Medicare patients, and the (MS-DRG) system which sets billing for Medicare patients. The MS-DRG is the most-widely used system today because of the growing numbers of Medicare patients.

## What is the difference between MS DRGs and APR DRGs?

The MS-DRG considers the reason for admission, the most costly secondary diagnosis based on a national average, and any particularly costly procedures—usually one related to the reason for admission. APR- DRGs were developed to also reflect the clinical complexity of the patient population.

## How are hospitals paid by Medicare?
