## What is an MS-DRG level of severity?

MS-DRGs provide up to three levels of severity for a particular condition. A “Base” MS-DRG combines all levels of severity into a single category. The MS-DRG numbers listed are the individual MS-DRGs that have been combined into a Base MS-DRG for reporting.

What are MS-DRG codes?

Diagnosis-related group (DRG) is a system which classifies hospital cases according to certain groups,also referred to as DRGs, which are expected to have similar hospital resource use (cost). They have been used in the United States since 1983.

### What is DRG classification?

The DRGs are a patient classification scheme which provides a means of relating the type of patients a hospital treats (i.e., its case mix) to the costs incurred by the hospital. The design and development of the DRGs began in the late sixties at Yale University.

What is MS and APR-DRG?

Just as with MS-DRGs, an APR-DRG payment is calculated by using an assigned numerical weight that is multiplied by a fixed dollar amount specific to each provider. Each base APR-DRG, however, considers severity of illness and risk of mortality instead of being based on a single complication or comorbidity.

#### How many MS-DRG categories are there?

There are over 740 DRG categories defined by the Centers for Medicare and Medicaid Services ( CMS . Each category is designed to be “clinically coherent.” In other words, all patients assigned to a MS-DRG are deemed to have a similar clinical condition.

How is MS-DRG 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.

## Where do you find the MS DRG code?

You have a couple of options when it comes to identifying the code. You could look it up in the ICD-10-CM/PCS code book, you could contact the coding department and ask for help, or look it up using a search engine or app on your smart device.

What is the highest number DRG?

Numbering of DRGs includes all numbers from 1 to 998.

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

DRGs vs. AP-DRGs are similar to DRGs, but also include a more detailed DRG breakdown for non-Medicare patients, particularly newborns and children. The APR-DRG structure is similar to the AP-DRG, but also measures severity of illness and risk of mortality in addition to resource utilization.

What does APR DRG stand for?

All Patients Refined Diagnosis Related Groups
All Patients Refined Diagnosis Related Groups (APR DRG) is a classification system that classifies patients according to their reason of admission, severity of illness and risk of mortality.
