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 is my Medicare DRG determined?
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.
Why is it necessary to recalculate the DRG relative weights?
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.
What is the difference between DRG and CMS rates?
The DRG payment rates cover most routine operating costs attributable to patient care, including routine nursing services, room and board, and diagnostic and ancillary services.19 The CMS creates a rate of payment based on the “average” cost to deliver care (bundled services) to a patient with a particular disease.
What is a Medicare DRG Bill?
The hospital submits a bill to their MAC for each Medicare patient treated. Based on the billing information, the MAC categorizes the case into a DRG. The base payment rate, or standardized amount (a dollar figure), includes a labor-related and non-labor-related share.

How are DRG weights calculated?
The DRG relative weights are estimates of the relative resource intensity of each DRG. These weights are computed by estimating the average resource intensity per case for each DRG, measured in dollars, and dividing each of those values by the average resource intensity per case for all DRG's, also measured in dollars.
What is DRG weight?
DRG Weights The CMS assigns a unique weight to each DRG. The weight reflects the average level of. resources for an average Medicare patient in the DRG, relative to the average level of resources. for all Medicare patients.28 The weights are intended to account for cost variations between. different types of treatments ...
What does the payment weight assigned to each DRG include?
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.
Does Medicare use DRGs to reduce costs?
Almost all State Medicaid programs using DRGs use a system like Medicare's in which participation in the program is open to all (or almost all) hospitals in the State and the State announces the algorithm it will use to determine how much it will pay for the cases.
How does DRG coding work?
DRGs are defined based on the principal diagnosis, secondary diagnoses, surgical procedures, age, sex and discharge status of the patients treated. Through DRGs, hospitals can gain an understanding of the patients being treated, the costs incurred and within reasonable limits, the services expected to be required.
What is the basic formula for calculating each MS-DRG hospital payment?
MS-DRG PAYMENT = RELATIVE WEIGHT × HOSPITAL RATE. The hospital's payment rate is defined by Federal regulations and is updated annually to reflect inflation, technical adjustments, and budgetary constraints. There are separate rate calculations for large urban hospitals and other hospitals.
How is CMI calculated?
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.
What is DRG base rate?
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 is APR DRG calculated?
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 does DRG affect payment for healthcare?
The introduction of DRGs shifted payment from a “cost plus profit” structure to a fixed case rate structure. Under a case rate reimbursement, the hospital is not paid more for a patient with a longer length of stay, or with days in higher intensity units, or receiving more services.
What are the pros and cons of DRG?
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.
Which are used to calculate reimbursement for hospital based Medicare?
Uses ambulatory payment classifications (APCs) to calculate reimbursement; was implemented for billing of hospital-based Medicare outpatient claims.
What is a DRG in Medicare?
DRG stands for diagnosis-related group. Medicare's DRG system is called the Medicare severity diagnosis-related group, or MS-DRG, which is used to determine hospital payments under the inpatient prospective payment system (IPPS). It's the system used to classify various diagnoses for inpatient hospital stays into groups and subgroups ...
What is a DRG relative weight?
DRGs with a relative weight of less than 1.0 are less resource-intensive to treat and are generally less costly to treat. DRG’s with a relative weight of more than 1.0 generally require more resources to treat and are more expensive to treat.
How much did nonprofit hospitals make in 2017?
The largest nonprofit hospitals, however, earned $21 billion in investment income in 2017, 4 and are certainly not struggling financially. The challenge is how to ensure that some hospitals aren't operating in the red under the same payment systems that put other hospitals well into the profitable realm.
When do hospitals assign DRG?
When you've been admitted as an inpatient to a hospital, that hospital assigns a DRG when you're discharged, basing it on the care you needed during your hospital stay. The hospital gets paid a fixed amount for that DRG, regardless of how much money it actually spends treating you.
Does a hospital make money on DRG?
If a hospital can effectively treat you for less money than Medicare pays it for your DRG, then the hospital makes money on that hospitalization. If the hospital spends more money caring for you than Medicare gives it for your DRG, then the hospital loses money on that hospitalization. David Sacks/Stone/Getty Images.
Does Medicare increase hospital base rate?
Each of these things tends to increase a hospital’s base payment rate. Each October, Medicare assigns every hospital a new base payment rate. In this way, Medicare can tweak how much it pays any given hospital, based not just on nationwide trends like inflation, but also on regional trends.
How many days does Medicare cover?
Medicare allows 90 covered benefit days for an episode of care under the inpatient hospital benefit. Each patient has an additional 60 lifetime reserve days. The patient may use these lifetime reserve days to cover additional non-covered days of an episode of care exceeding 90 days. High Cost Outlier.
How long does Medicare cover inpatient hospital care?
The inpatient hospital benefit covers 90 days of care per episode of illness with an additional 60-day lifetime reserve.
What is a physician order?
The physician order meets 42 CFR Section 412.3 (b), which states: A qualified, licensed physician must order the patient’s admission and have admitting privileges at the hospital as permitted by state law. The physician is knowledgeable about the patient’s hospital course, medical plan of care, and current condition.
How long does it take to travel between a hospital and a like hospital?
The hospital is rural and because of distance, posted speed limits, and predictable weather conditions, travel time between the hospital and the nearest like hospital is at least 45 minutes. A like hospital is a hospital that provides short-term, acute care.
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.
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
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.
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.
What is a DRG in PPS?
A key part of PPS is the categorization of medical and surgical services into diagnosis-related groups (DRGs). The DRGs “bundle” services (labor and non-labor resources) that are needed to treat a patient with a particular disease. The DRG payment rates cover most routine operating costs attributable to patient care, including routine nursing services, room and board, and diagnostic and ancillary services.19 The CMS creates a rate of payment based on the “average” cost to deliver care (bundled services) to a patient with a particular disease. The DRG rates do not expressly include direct medical education costs, outpatient services, or services covered by Medicare Part B.20 For fiscal year 2002, there are 499 DRGs with a prospective price based on the average resources used in treating patients under the specific DRG.21
What is the resource based relative value system?
Medicare has adopted the Resource Based Relative Value System to reimburse providers for services provided to Medicare patients. Care is characterized by a CPT code. Each CPT code has an associate set of relative values (RVUs), consisting of Facility, Physician Work, and Malpractice RVUs.
Can Medicare bill VA?
VA cannot bill Medicare for care provided to Veterans. However, calculation of a hypothetical Medicare reimbursement is useful to cost analysts who are interested in estimating the resources used to provide VA inpatient care. Medicare reimburses both hospitals and providers for the cost of inpatient stays.
What does DRG mean in Medicare?
A DRG dictates how much Medicare pays the hospital if you’re admitted as an inpatient. However, keep in mind that your DRG does not affect what you owe for an inpatient admission when you have Medicare Part A coverage, assuming you receive medically necessary care and that your hospital accepts Medicare.
How is a DRG determined?
How is a Medicare DRG determined? A Medicare DRG is determined by the diagnosis that caused you to become hospitalized as well as up to 24 secondary diagnoses (otherwise known as complications and comorbidities) you may have. Medical coders assign ICD-10 diagnosis codes to represent each of these conditions.
Why was the DRG system created?
The DRG system was created to standardize hospital reimbursement for Medicare patients while also taking regional factors into account. Another goal was to incentivize hospitals to become more efficient. If your hospital spends less money taking care of you than the DRG payment it receives, it makes a profit.
What is Medicare DRG?
What exactly is a Medicare DRG? A Medicare DRG (often referred to as a Medicare Severity DRG) is a payment classification system that groups clinically-similar conditions that require similar amounts of inpatient resources. It’s a way for Medicare to easily pay your hospital after an inpatient stay.
What is a DRG in 2021?
April 27, 2021. A Medicare diagnosis related group (DRG) affects the pre-determined amount that Medicare pays your hospital after an inpatient admission. Understanding what it means can help you gain insight into the cost of your care. As you probably know, healthcare is filled with acronyms. Although you may be familiar with many ...
How to contact Medicare DRG?
Speak with a licensed insurance agent. 1-800-557-6059 | TTY 711, 24/7. 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:
What happens if you require extra hospital resources because you are particularly sick?
If you require extra hospital resources because you are particularly sick, your hospital may also receive an outlier payment that goes above and beyond the normal DRG based payment.
