Is a higher or lower CMI better?
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.
What is a patient case mix index?
The Case Mix Index (CMI) is the average relative DRG weight of a hospital's inpatient discharges, calculated by summing the Medicare Severity-Diagnosis Related Group (MS-DRG) weight for each discharge and dividing the total by the number of discharges.
What is case mix index and why is it important?
Case mix index is a measure used by the Centers for Medicare and Medicaid Services (CMS) to determine hospital reimbursement rates for Medicare and Medicaid beneficiaries. This measure reflects the diversity, complexity, and severity of patient illnesses treated at a given hospital or other healthcare facility.
Is a high CMI good?
Case mix index measures the care needed for patients and residents. A higher CMI means that a long term care facility or hospital has treated a significant number of resource-intensive patients. This, in turn, results in a higher reimbursement rate for the SNF.
What is a case mix in healthcare?

How does CMI affect reimbursement?
Facilities with higher CMI receive more insurance reimbursement. Thus, the higher the CMI, the lower the adjusted cost per patient per day for the hospital.
What does a low CMI mean?
The adjusted average cost per patient would reflect the charges reported for the types of cases treated in that year. If a hospital has a CMI greater than 1.00, their adjusted cost per patient or per day will be lower and conversely if a hospital has a CMI less than 1.00, their adjusted cost will be higher.
What is the primary use of the case mix index quizlet?
A measurement index used to describe a population that is being served, to determine reimbursement, and to identify differences in practice patterns or coding complexity.

Casemix provides the healthcare industry with a consistent method of classifying types of patients, their treatment and associated costs. It involves developing and implementing a patient classification system that groups patients according to their clinical conditions.
What does case mix adjusted mean?
Case-mix adjustment uses statistical models to predict what each hospital's ratings would have been for a standard patient or population, thereby removing from comparisons the predictable effects of differences in patient characteristics that are consistent across hospitals.
How is case mix related to coding?
The practice of coding, essentially groups patients using statistical codes. The coded data can be grouped further into Diagnosis-Related Groups (DRGs), which are used in the billing process by hospitals and practices; as the "cost per item" of healthcare is based on the casemix.
What is case mix index (CMI)?
Case mix index is a measure used by the Centers for Medicare and Medicaid Services (CMS) to determine hospital reimbursement rates for Medicare and Medicaid beneficiaries. This measure reflects the diversity, complexity, and severity of patient illnesses treated at a given hospital or other healthcare facility.
What does higher case mix mean?

What does a lower case mix index mean?
Though the patients that they care for and the services that they provide are largely the same, a lower case mix index could indicate that one hospital is documenting its cases less effectively.
Why is case mix index important?
Why is case mix index an important healthcare metric? Not only does case mix index play a central role in hospital finances, it is also an important indicator of hospital performance and clinical documentation.
What Is CMI?
Let’s start with the most basic question: what is CMI? According to Definitive Healthcare, Case Mix Index (CMI) is a measure used by the Centres for Medicare and Medicaid Services (CMS) to determine reimbursement rates. CMI is an aggregate value that is assigned to individual patients in a long term care facility. That value, in turn, determines how much resources should be allocated to a resident in a skilled nursing facility.
Why is a higher CMI important?
A higher CMI is beneficial for SNFs and hospitals, as it results in higher reimbursements for SNFs and hospitals. The factors that affect a Case Mix Index include documentation, coding accuracy, and highly-weighted DRGs.
What does high CMI mean in a hospital?
According to Health Leaders Media, when an SNF or hospital has a high CMI, it tends to mean that the hospital is treating sicker patients. This results in the facility receiving greater reimbursement on account of the care they are providing. Thus CMI plays a vital role in the finances of an SNF and hospitals. Moskowitz talks about how when screening long term care facilities, “We look at the population of the long term care facility as well as their procedures. We then ask ourselves, ‘Can we improve the Case Mix Index of this facility?’”
Why is CAC important?
Improves workflow: CAC helps coders work more efficiently, as they no longer waste time searching for codes or gathering documents. Because their workflow is improved, it results in faster submission of insurance claims, better compliance with regulations, and more accurate documentation that results in a higher Case Mix Index
How often should SNFs calculate their case mix index?
It is considered best practice for SNFs to calculate their Case Mix Index monthly and annually. As mentioned above, CMI healthcare is affected by a facility’s documentation practices. HC Pro notes that, although SNFs and hospitals cannot provide unnecessary services for the sake of improving their CMI, there are other ways to improve their CMI.
How does CAC work in healthcare?
CAC works by scanning and analyzing the EHR documents, highlighting key terminology, and recommending appropriate codes for diagnoses and medical procedures.
What is DRG weight?
Law Insider defines DRG-relative weights as: the average standardized costs for cases assigned to that DRG (Diagnosis Related Groups) divided by the average standardized costs for cases assigned to all DRGs.
What is CMI in medical terms?
The CMI is the average of relative weights of DRGs assigned to a specific population or group. For example, to compute the CMI for all patients discharged in the month of March, take the average of the relative weights for every DRG assigned for discharges within that time period.
What is the CMI measure?
A: The CMI is a very popular measure used to evaluate CDI effectiveness. Unfortunately, it is not actually the best measure due to the number of factors that influence a facility’s CMI.
Does gatekeeping affect CMI?
Gatekeeping efforts also affect the CMI. If patients are admitted with principal diagnoses that likely don’t require an inpatient stay (symptoms, transient ischemic strokes, syncope, etc.), the relative weights will reflect the lower resource use and the overall CMI will be lower.
Does CMI increase in winter?
For example, in the winter months, many patients of Medicare age relocate to warmer climates such as Florida or Arizona. This influx of “snowbirds” likely will lend to an increase in CMI.
What is CMS case mix index?
Case Mix Index (CMI) is used by the Centers for Medicare and Medicaid Services (CMS) to determine funding allocation for Medicare and Medicaid beneficiaries in hospitals and other care facilities. Patients are classified into diagnosis-related groups (DRGs) depending on condition, case complexity, and medical needs.
Why is CMI high?
The concentration of high CMI is likely due to barriers to care access in rural parts of these states, and high concentrations of patients with chronic illnesses that require patients to seek insurance through Medicare and Medicaid.
What is the average CMI of a hospital?
The following tables list the top 25 hospitals with the largest case mix index. The average CMI of all 25 hospitals is 3.48, though CMIs range from 3.02 to 5.26.
What is case mix?
Case mix is used to find and adjust the average care cost per patient at a hospital or other care facility based on the patient population demographics. This can have an impact on quality ratings and reimbursement rates, as the weight of each DRG is determined by CMS.
Why is CMI important?
Facilities with higher CMI receive more insurance reimbursement. Thus, the higher the CMI, the lower the adjusted cost per patient per day for the hospital.
What is the most impactful documentation item that impacts CMI?
The most impactful documentation item that effects CMI is diagnosis. A physician can provide the exact same level of care for the same patient but the reimbursement numbers can vary widely based on what the physician documents. Optimally documenting CMI requires an accurate primary diagnosis because that diagnosis determines the Medicare Severity Diagnosis Related Groups (MS-DRG).
How does CMI affect quality?
Increased CMI results in higher reimbursement and lower adjusted cost per patient per day, which equates to a significant revenue enhancement for hospitals. Not only that, it also positively impacts Observed Over Expected (O/E) ratios for quality scores, including mortality and expected complications. As CMI increases, so do quality and HAC scores, which impacts quality ratings such as Leapfrog, Healthgrades, and Medicare Star ratings.
How does physician documentation affect CMI?
Physician documentation has a direct impact on CMI. When physicians accurately portray the acuity of their patients, it equates to CMI and more reimbursement for the hospital. The most effective way to improve CMI is thorough documentation training and consistent follow-through as it relates to ongoing documentation review and education.
What is CMI in healthcare?
CMI is the average sum of the relative weights (RW) of all patients treated in a facility in a specified time. It measures resource consumption and cost of providing care at a facility. When a hospital has a higher CMI, they treat more complex, sicker patients and receive higher reimbursement rates.
What is inpatient documentation training?
The inpatient documentation training focuses on educating providers on the commonly down-coded areas of charts, including:
Why is benchmarking important for DRG?
Benchmarking your performance relative to your peers allows you to compare specific DRG reporting with other hospitals, and can help identify areas where you may not be measuring up. This type of comparative analysis is another way to highlight where your documentation may be lacking and negatively impacting the accuracy of your CMI. The MDaudit metric card shown above shows the peer benchmark range for Surgical DRGs for CCs/MCCS, allowing you to assess your organization’s performance on this metric relative to similar organizations.
How to ensure you have the correct CMS reimbursement rate?
You can ensure you have the appropriate CMI by leveraging the right software tools to continuously monitor activity and compare results with peer organizations.
What does a high CMI mean?
Since a high CMI indicates a more complex and resource-intensive case load (resulting in a higher reimbursement rate), there must be corresponding clinical documentation in place to support these types of cases. Without this proof, the CMI would be lowered and negatively impact the amount of reimbursement to which an organization is legitimately entitled.
How to improve CMI?
There are two main ways that data analytics can lead to improved CMI accuracy: continuous monitoring and benchmarking.
What is the CMI index?
What is Case Mix Index and why is it important? CMI is a metric that the Centers for Medicare and Medicaid Services (CMS) uses to assess the mixture, clinical complexity, and resource needs of all patients treated in the hospital. It reflects the average relative DRG weight of a hospital’s inpatient discharges.
Why is tracking and analyzing your own clinical documentation quality metrics/KPIs important?
Tracking and analyzing your own clinical documentation quality metrics/KPIs is important in determining that clinical engagements are being captured accurately. But it is just as important to compare your internal metrics with a cohort of similar organizations.
How often should you review a chart?
This method is both risky and expensive. Reviewing random cases for documentation errors 2-4 times a year may waste precious resources on coders who are performing well while risking overlooking those who are doing poorly.
