The national average payment for each DRG is calculated by multip lying the current relative weight of the DRG by the national average hospital Medicare base rate.
How your DRG is determined for billing?
individual hospital’s base payment rate by the weight of the DRG. The weight of a DRG is determined by the intensity of resources, on average, that are needed to treat that kind of case. When a patient is discharged, the physician summarizes information on a discharge face sheet. This information includes principal diagnosis, additional diagnoses, and procedures performed during the stay.
What is DRG based on?
Your Medicare DRG is based on your severity of illness, risk of mortality, prognosis, treatment difficulty and need for intervention as well as the resource intensity necessary to care for you. Here’s how it works:
How does secondary diagnosis affect relative weight?
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.
What does DRG stand for?
DRG: Data Retention Gated-Ground (energy reduction circuit design technique) DRG: Distant Red ...
How are DRG rates determined?
MS-DRG-based Payments The MS-DRG payment for a Medicare patient is determined by multiplying the relative weight for the MS-DRG by the hospital's blended rate: MS-DRG PAYMENT = RELATIVE WEIGHT × HOSPITAL RATE.
What is a DRG case rate?
Diagnosis-related group reimbursement (DRG) is a reimbursement system for inpatient charges from facilities. This system assigns payment levels to each DRG based on the average cost of treating all TRICARE beneficiaries in a given DRG.
What is DRG payment based on?
Each DRG has a payment weight assigned to it, based on the average resources used to treat Medicare patients in that DRG. The base payment rate is divided into a labor-related and nonlabor share.
How is DRG relative weight calculated?
A hospital's CMI represents the average diagnosis-related group (DRG) relative weight for that hospital. It is calculated by summing the DRG weights for all Medicare discharges and dividing by the number of discharges.
What are the 3 DRG options?
There are currently three major versions of the DRG in use: basic DRGs, All Patient DRGs, and All Patient Refined DRGs. The basic DRGs are used by the Centers for Medicare and Medicaid Services (CMS) for hospital payment for Medicare beneficiaries.
What is the highest number DRG?
Numbering of DRGs includes all numbers from 1 to 998.
Are DRGs only for Medicare?
Are DRGs only for Medicare? No, some private insurers use DRGs as well, though their specific DRG calculations might be different.
Is fee for service the same as DRG?
The fee-for-service model does not lend itself to healthcare providers and payers working together to manage risk factors for medical costs. By contrast, the DRG payment model uses fixed reimbursements based on DRG payment model, allowing providers to reduce unnecessary medical services to a large degree.
What are the DRG codes?
DRG Codes (Diagnosis Related Group) 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 weight?
Each DRG weight represents the average resources required to care for cases in that particular DRG, relative to the average resources used to treat cases in all DRGs. Congress recognized that it would be necessary to recalculate the DRG relative weights periodically to account for changes in resource consumption.
What is a DRG in healthcare?
A diagnosis-related group (DRG) is a case-mix complexity system implemented to categorize patients with similar clinical diagnoses in order to better control hospital costs and determine payor reimbursement rates.
Why is the case mix index important for a hospital?
The CMI reflects the diversity, clinical complexity, and resource needs of all the patients in the hospital. A higher CMI indicates a more complex and resource-intensive case load.
How does case mix index affect reimbursement?
A higher CMI means more reimbursement dollars for providing care because it indicates that a hospital is treating a sicker patient population. Increasing the CMI hinges on having clinical documentation that accurately reflects the severity level of patients' conditions.
What is Irdrg?
This new insurance payment system, known in many countries as International Refined Diagnostics Related Groups (IR-DRG) for inpatient hospital payments, is expected to be fully implemented in Dubai in the last quarter of 2019.
Assigning a DRG
The CMS analyzes statistics for each DRG to see how much treatment patients in that group require. When the hospital submits a bill, the CMS normally assigns a patient to a single DRG.
Calculating the Rate
To start its calculations, the CMS sets basic labor and non-labor payments for a hospital stay. It then multiplies those payments by a weighting factor based on the DRG. The DRG multiplier depends on how much treatment patients in that group require.
What does it mean when a hospital has a DRG?
A DRG title that includes “with MCC” or “with CC” means that, in addition to treating the principal diagnosis you were admitted for, the hospital also used its resources to treat a comorbid condition during your hospitalization. The comorbid condition likely increased the resources the hospital had to use to treat you, which is why the hospital was paid more than they would have received if you'd only had a single diagnosis and no comorbid conditions.
What happens if a hospital spends more than the DRG payment?
If, while treating the hospitalized patient, the hospital spends more money than the DRG payment, the hospital will lose money on that patient’s hospitalization. This is meant to control healthcare costs by encouraging the efficient care of hospitalized patients.
What is a DRG with a CC?
This is known as a DRG with a CC or a comorbid condition. A higher-paying DRG for the principal diagnosis with a major comorbid condition, known as a DRG with an MCC or major comorbid condition.
Why are there three different DRGs?
In cases like this, there may be three different DRGs, known as a DRG triplet: A lower-paying DRG for the principal diagnosis without any comorbid conditions or complications.
How does Medicare pay hospitals?
Medicare and many health insurance companies pay hospitals using DRGs, or diagnostic related groupings. This means the hospital gets paid based on the admitted patient’s diagnosis and prognosis, rather than based on what it actually spent caring for the hospitalized patient.

What is the first step in assigning a DRG?
More About Step 1: Principal Diagnosis. The most important part of assigning a DRG is getting the correct principal diagnosis. This seems simple but can be tough, especially when a patient has several different medical problems going on at the same time.
What is the principal diagnosis?
According to the Centers for Medicare and Medicaid Services (CMS), “The principal diagnosis is the condition established after study to be chiefly responsible for the admission.” 3 .
What is a DRG in Medicare?
A DRG, or diagnostic related group, is how Medicare and some health insurance companies categorize hospitalization costs and determine how much to pay for your hospital stay. Rather than pay the hospital for each specific service it provides, Medicare or private insurers pay a predetermined amount based on your Diagnostic Related Group.
Why is DRG payment important?
The DRG payment system encourages hospitals to be more efficient and takes away their incentive to over-treat you. However, it's a double-edged sword. Hospitals are now eager to discharge you as soon as possible and are sometimes accused of discharging people before they’re healthy enough to go home safely. 6 .
What was the DRG in the 1980s?
What resulted was the DRG. Starting in the 1980s, DRGs changed how Medicare pays hospitals. 3 .
What was included in the DRG bill?
Before the DRG system was introduced in the 1980s, the hospital would send a bill to Medicare or your insurance company that included charges for every Band-Aid, X-ray, alcohol swab, bedpan, and aspirin, plus a room charge for each day you were hospitalized.
What happens if a hospital spends less than the DRG payment?
Your age and gender can also be taken into consideration for the DRG. 2 . If the hospital spends less than the DRG payment on your treatment, it makes a profit. If it spends more than the DRG payment treating you, it loses money. 4 .
What is DRG system?
The DRG system is intended to standardize hospital reimbursement, taking into consideration where a hospital is located, what type of patients are being treated, and other regional factors. 4 . The implementation of the DRG system was not without its challenges.
Why is the hospital eager to use DRG?
Since those services mean you can be discharged sooner, the hospital is eager to use them so it's more likely to make a profit from the DRG payment.
How does the DRG work?
Therefore, under the IPPS, we pay for inpatient hospital services on a rate per discharge basis that varies according to the DRG to which a beneficiary's stay is assigned. 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 . Each DRG weight represents the average resources required to care for cases in that particular DRG, relative to the average resources used to treat cases in all DRGs.
Why do we have to recalculate DRG?
Congress recognized that it would be necessary to recalculate the DRG relative weights periodically to account for changes in resource consumption. Accordingly, section 1886 (d) (4) (C) of the Act requires that the Secretary adjust the DRG classifications and relative weights at least annually. These adjustments are made to reflect changes in treatment patterns, technology, and any other factors that may change the relative use of hospital resources.
What is Medicare code edits v37?
Definition of Medicare Code Edits v37 (ZIP) : The ICD-10 Definitions of Medicare Code Edits file contains the following: A description of each coding edit with the corresponding code lists as well as all the edits and the code lists effective for FY 2020. Zip file contains a PDF and text file that is 508 compliant.
How many MS-DRGs are required for 21st century cures?
The 21 st Century Cures Act requires that by January 1, 2018, the Secretary develop an informational “HCPCS version” of at least 10 surgical MS-DRGs. Under the HCPCS version of the MS-DRGs developed for this requirement, to the extent feasible, the MS-DRG assignment for a given service furnished to an outpatient (billed using a HCPCS code) is as similar as possible to the MS-DRG assignment for that service if furnished to an inpatient (billed using an ICD-10-PCS code).
Where to send MS-DRG classification changes?
Requests for annual MS-DRG classification changes and any MS-DRG related inquiries should be sent to the MSDRGClassificationChange@ cms.hhs.gov mailbox.
Is MS-DRG Java updated?
The MS-DRG Java zip file has been updated to include a missing dependency required for testing. The MS-DRG Java API and calling example documentation has been updated to include references to this dependency as well as corrections to make method naming consist. The MS-DRG and MCE Java Mainframe deliverables have updated install guide PDF with corrections for clarity. There were no changes made to the functionality or content of MS-DRG or MCE.
How to calculate DRG?
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. The standardized amount is the sum of: (1) a labor component which represents labor cost variations among different areas of the country and (2) a non-labor component which represents a geographic calculation based on whether the hospital is located in a large urban, or other area. The labor component is then adjusted by a wage index.42 If applicable, cost outlier, disproportionate share, and indirect medical education payments are added to the payment.
What are the factors that determine DRG payments?
In addition to the four factors discussed above, there are other factors considered in calculating DRG payments depending on whether the hospital is considered a sole community hospital, a Medicare dependent rural hospital, or a regional referral hospital. In each instance, there are special payment rules. A hospital may be designated as a sole community hospital if, among other things, it is (1) located more than 35 miles from another hospital, (2) the sole source of inpatient hospital services in a geographic area, or (3) designated by the Secretary as a “critical access hospital.”39 A Medicare dependent rural hospital is one that depends on Medicare for at least 60 percent of its patient days or discharges. A regional referral hospital is one that serves as a referral center for other hospitals in its area.40 These hospitals are reimbursed according to the payment rate for large urban areas.
How does CMS respond to MedPAC?
CMS responds to MedPAC’s recommendations in the same manner that it responds to the general public’s comments — through the public comment process in the Federal Register. CMS systematically responds to each MedPAC recommendation. Some of the recommendations are implemented, others are not. Some of MedPAC’s recommendations would require legislative changes which are beyond CMS’ control. In response to MedPAC’s June 2000 recommendation that the Secretary should adopt the All Patients Refined Diagnosis Related Groups, CMS agreed that this change would reduce discrepancies between payments and costs, but declined to adopt such a change because it would not be able to predict with accuracy how such a change may affect coding behavior. Furthermore, CMS believes that such a change would require specific legislative authority.62
What is the process of updating DRG codes?
The process by which the DRG codes are updated is called reclassification. It involves not only an assessment of the appropriateness of the DRG assignment within MDCs, but it also entails reclassifying the codes to account for new medical technologies and treatment patterns.
Why does CMS reclassify DRGs?
CMS reclassifies the DRGs and recalibrates the DRG weights to decide what changes are necessary to compensate adequately for costs under PPS. The recalibration and reclassification processes are integrally related. The reclassification update occurs first, followed by recalibration of the weights.
How does CMS update DRG weights?
The process by which the DRG weights are updated is referred to as recalibration. Through recalibration, CMS updates the DRG system to account for changes in medical practices, technology, and the range of cases within the DRGs (commonly referred to as “case complexity”). Recalibration ensures that the weights accurately reflect the value of resources used for each patient classification. The Social Security Act requires CMS to recalibrate the DRG weights in a manner that maintains “budget neutrality” of the total program. Budget neutrality requires that the estimated payments for the hospital benefit are not greater or less than 25 percent of the payment amounts that would have been payable for the same services in Fiscal Year 1984.51
What is PPS calculation?
The PPS rate calculation begins with the “standardized amounts.” The standardized amounts are composed of a labor and a non-labor component. The large urban rates are used because San Francisco is in the large urban category.

Benefits
- If a hospital can treat a patient while spending less money than the DRG payment for that illness, the hospital makes a profit. If, while treating the hospitalized patient, the hospital spends more money than the DRG payment, the hospital will lose money on that patients hospitalization. This is meant to control health care costs by encouraging the efficient care of hospitalized patients. If y…
Results
- If youre a patient, understanding the basics of what factors impact your DRG assignment can help you better understand your hospital bill, what your health insurance company or Medicare is paying for, or why youve been assigned a particular DRG.
Introduction
- This is a simplified run-down of the basic steps a hospitals coder uses to determine the DRG of a hospitalized patient. This isnt exactly how the coder does it; in the real world, coders have a lot of help from software. Lets say elderly Mrs. Gomez comes to the hospital with a broken femoral neck, known more commonly as a broken hip. She requires s...
Treatment
- Mrs. Gomezs principal diagnosis would be a fracture of the neck of the femur. Her surgical procedure is related to her principal diagnosis and is a total hip replacement. Additionally, she has a major comorbid condition: acute systolic congestive heart failure.
Diagnosis
- The most important part of assigning a DRG is getting the correct principal diagnosis. This seems simple but can be tough, especially when a patient has several different medical problems going on at the same time. According to CMS, The principal diagnosis is the condition established after study to be chiefly responsible for the admission. The principal diagnosis must be a problem tha…
Risks
- Although this seems cut and dry, like most things about health insurance and Medicare, its not. There are a couple of rules that determine if and how a surgical procedure impacts a DRG.
Definitions
- First, Medicare defines what counts as a surgical procedure for the purposes of assigning a DRG, and what doesnt count as a surgical procedure. Some things that seem like surgical procedures to the patient having the procedure dont actually count as a surgical procedure when assigning your DRG. If youre a patient looking at your bill or explanation of benefits and your health insuran…
Classification
- Second, its important to know whether the surgical procedure in question is in the same major diagnostic category as the principal diagnosis. Every principal diagnosis is part of a major diagnostic category, roughly based on body systems. If Medicare considers your surgical procedure to be within the same major diagnostic category as your principal diagnosis, your DR…
