What is the difference between DRG and APR DRG?
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 is an Ungroupable DRG?
Diagnosis-related group (DRG) is a system to classify hospital cases into one of originally 467 groups, with the last group (coded as 470 through v24, 999 thereafter) being “Ungroupable”. The system is also referred to as “the DRGs”, and its intent was to identify the “products” that a hospital provides.
What is MS DRG and APR DRG?
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.
What is APR DRG in healthcare?
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.

What is used to define a newborn APR DRG?
Here are some important definitions that impact the MS-DRG assignment: Neonate – an infant less than four weeks old. Prematurity – the birth weight of 1,000-2,499 grams, or gestational age of 27-36 completed weeks of gestation.
Who uses APR DRG?
3M APR DRGs are used by payers, hospitals and researchers. Payers often use 3M APR DRGs as the basis for an inpatient prospective payment method and as the risk adjustor in measuring hospital quality.
How is an APR DRG grouped?
Each APR-DRG is subdivided into four severity of illness subclasses and four risk of mortality subclasses. In addition there are two error APR-DRGs (955,956) that are not subdivided into subclasses. The combination of APR-DRG and severity subclasses results in 1262 possible APR-DRG assignments.
How many states use APR DRG?
As of February 2021, 27 state Medicaid programs use 3M APR DRGs to pay hospitals, as do approximately a dozen commercial payers and Medicaid managed care organizations.
How many Apr DRGs are there?
APR-DRGs have the most comprehensive and complete pediatric logic of any severity of illness classification system. There are 315 base APR-DRGs (version 27.0). Each APR-DRG is subdivided into four severity of illness subclasses and four risk of mortality subclasses.
How are all patient refined DRGs different from AP-DRGs?
The All Patient Refined DRGs (APR-DRG) incorporate severity of illness subclasses into the AP-DRGs. The APR-DRGs expand the basic DRG structure by adding four subclasses to each DRG. The addition of the four subclasses addresses patient differences relating to severity of illness and risk of mortality.
How many base 3M APR DRGs are there?
Each of the 332 base 3M APR DRGs classifies patients based on clinical similarities and their use of hospital resources. Further, each base 3M APR DRG is divided into four levels of severity of illness, for a total of 1,330 3M APR DRGs (including 2 error DRGs).
What are the different versions of the DRG?
There are currently three major versions of the DRG in use: basic DRGs, All Patient DRGs, and All Patient Refined DRGs. DRGs are used by Medicare and measure the typical resource use of an inpatient stay. AP-DRGs are similar to DRGs, but also include a more detailed DRG breakdown for non-Medicare patients, particularly newborns and children.
What are the base DRGs for 3M pneumonia?
For example, 3M APR DRG 139-1 is Other Pneumonia, severity of illness 1 (minor) while 3M APR DRG 139-4 is Other Pneumonia, severity of illness 4 (extreme). Each base DRG also has four risk-of-mortality levels.
