What contributes to a hospital’s CMI? 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 is a good CMI for a hospital? The average CMI of all 25 hospitals is 3.48, though CMIs range from 3.02 to 5.26. This is a shift up from the last reporting period, which ranged from 2.75 to 4.88. CMI does not appear to correlate to the number of annual discharges, with discharges from the top 10 hospitals ranging from 5,531 to 87 annually.
What affects CMI? It’s important to remember, however, that this metric can be impacted by many different factors, including: Coding accuracy. Documentation specificity. High volumes of highly weighted DRGs (like organ transplantations, cardiothoracic surgeries, or neurosurgeries) Annual updates to relative MS-DRG weights.
How do I increase my hospital 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 contributes to a hospital’s CMI? – Related Questions
What is considered a high CMI?
The financial department monitors case-mix index (CMI), and in an ideal world, the hospital’s CMI would be as high as possible. A high CMI means the hospital performs big-ticket services and therefore receives more money per patient. A 0.10 change in CMI affects a hospital with a hospital specific rate of $4,500.
How is hospital CMI 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. CMIs are calculated using both transfer-adjusted cases and unadjusted cases.
What is CMI in long term care?
Case Mix Index CMI Weight or numeric score assigned to each RUG-III group that reflects the relative resources predicted to provide care to a resident. The higher the case mix weight, the greater the resource requirements for the resident.
How is CMI calculated example?
Total all of the relative weights and divide that number by the total number of individual DRGs. The result is your hospital’s CMI for the calculation period. For example, if your hospital billed 35 DRGs for a one-month period and relative weights totaled 40, the CMI for one month is 0.875, or 35 divided by 40.
How do you read CMI?
CMI is calculated by adding the relative weights (as defined by DRGs) for all patient admissions and then dividing that number by the total number of admissions during the same time frame.
What is the relationship between CMI and 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.
Why is CMI important?
CMI is an important performance indicator for your hospital not because it tells a big story in and of itself, but because of how it impacts your hospital’s finances. CMI is a measure of the average severity level of a hospital’s procedures. While the logic may be debatable, the revenue impact on hospitals is not.
What is CMI adjusted length of stay?
We encourage hospitals to use a modified measure as a baseline for efficiency: CMI-adjusted length of stay. It is defined as the ratio of the number of days of hospital care that were utilized to care for patients adjusted for the documented severity of the illnesses.
What is the relationship between types of patients and a CMI?
CMI is a relative value assigned to each Diagnostic Related Group (DRG), and determines the allocation of resources for patient care. An increasing CMI may indicate a hospital is servicing more “complex patients” and would therefore be receiving more insurance reimbursement per patient.
Is a high CMI good or bad?
If the CMI is high, DRG payments are larger. It indicates a lower average cost per patient. So, in theory, you get more money to spend. The inverse, however, is not good.
What does Case Mix mean in healthcare?
Case-mix involves patient classification as a tool to improve financial and clinical management in a clinical facility. The term case-mix refers to the type or mix of patients treated by a hospital or unit. The facility is reimbursed a predetermined amount for each patient episode.

What is CMI nursing home?

How are CMI adjusted discharges calculated?
Adjusted Discharges = Inpatient Discharges + [(Gross Outpatient Revenue/Gross Inpatient Revenue) X Inpatient Discharges] The case mix adjusted discharge metric is determined by multiplying the result of this formula by the inpatient case mix index.
