How are CMI adjusted discharges 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.
Is it better to have a high or low CMI?
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 good CMI score?
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 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.
How CMI affects a facility?
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.
How does CMI 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 =.
How do I raise my CMI score?
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 adjusted?
The CMI-Adjusted Combined LOS Ratio is a high level operational efficiency measure. 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 CMI and reimbursement?
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.
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.
how are CMI adjusted discharges 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 the CMI for 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.
How is CMI calculated for Medicare?
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 a case mix adjusted discharge?
adjusted discharge or an adjusted discharge that has been inpatient case mix adjusted. A new metric for measuring total hospital volume correlates significantly better with cost than do adjusted discharges—without the same inherent flaws. time to replace adjusted discharges
