A higher CMI corresponds to increased consumption of resources and increased cost of patient care, resulting in increased reimbursement to the facility from government and private payers, like CMS.
What is a case mix index in healthcare?
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.Why is Case Mix important in evaluating different healthcare providers?
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.
What impact does case mix index have on 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 affects CMI?Changes in the location of treatment can affect the CMI. The shift of surgery to outpatient settings tends to increase the CMI, because the majority of those patients no longer hospitalized would have been classified into DRG’s with lower-than-average weights.
Article first time published onIs High CMI good or bad?
An easier way to explain CMI is to compare it to a student’s Grade Point Average (GPA). A higher GPA is reflective of a student’s academic success. Likewise, a higher CMI for a hospital is reflective of a successful DRG program.
Why does the case mix index look like the relative weight?
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.
How does case mix index affect Hppd?
Case Mix Index was significantly associated with HPPD (β =0.33, p <. 001); Model 5 explained 57.4 percent of the variance in HPPD. Finally, both unit level CMI (β =−0.29, p <. 01) and inadequate number of assistive personnel (β=0.30, p =.

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.
Is case mix index still a relevant key performance indicator?
Eventually, the acuity of the patient population will be reflected in the CMI. That does not mean organizations should eliminate their CDI departments, it just means that CMI is likely to be a less relevant indicator of a successful CDI department.
What is case mix adjustment?
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.

What is considered a high case mix index?
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 CMI adjusted patient days calculated?
Adjusted hospital days were calculated based on the following formula: [1 + (outpatient gross charges/inpatient gross charges)] * patient days. CMI-adjusted discharges and CMI-adjusted hospital days were calculated by multiplying CMI by discharges and adjusted hospital days, respectively.
What does CMI stand for in immunology?
Cell-mediated immunity (CMI) is a T-cell–mediated defense mechanism against microbes that survive within phagocytes or infect nonphagocytic cells.
What is the purpose of a DRG?
The purpose of the DRGs is to relate a hospital’s case mix to the resource demands and associated costs experienced by the hospital.
What is the relationship between types of patients and a CMI?
An increasing CMI may indicate a hospital is servicing more “complex patients” and would therefore be receiving more insurance reimbursement per patient. By contrast, a decreasing CMI may indicate a change in surgical volume or a lack of complete documentation or accurate coding to the appropriate DRG.
How can weaknesses in documentation impact a facility's CMI?
Documentation directly impacts CMI. For instance, if physicians are too vague in their descriptions, the result could could be undercoding, which lowers the CMI and leaves revenue on the table.
