The CMI of a hospital reflects the diversity, clinical complexity and the needs for resources in the population of all the patients in the hospital. The adjusted average cost per patient would reflect the charges reported for the types of cases treated in that year.Subsequently, one may also ask, what affects CMI?
However, CMI may be affected by the accuracy of physician documentation and the skill and experience of the coder who abstracts data from the medical record and assigns ICD-9-CM codes.
Furthermore, what does a high CMI mean? A high CMI means the hospital performs big-ticket services and therefore receives more money per patient. Finance departments consider CMI when determining the hospital's budget. If the hospital's actual CMI is less than what the finance department predicted, the hospital may experience a loss in revenue.
Likewise, people ask, how does CMI affect 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 is CMI calculated example?
Calculate the CMI CMI is the sum of all DRG-relative weights divided by the number of patients for a specific period. 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.
What is a good CMI?
“…the CMI is a good tool to compare area hospital performance at a similar acuity level for medical and surgical care. The DRG for a patient admission that does not meet medical necessity, indicates the patient's care could have been provided on an outpatient basis. It could also have a critical impact on the CMI.”What does CMI mean in healthcare?
Case mix index

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.Which has more influence on the CMI RW or volume?
Because surgical MS-DRGs are higher weighted than medical MS-DRGs (because the cost of the surgery is typically higher and therefore represented in higher RW) an increase in the volume of surgical cases can increase the overall CMI.What is the national average CMI for hospitals?
The average CMI of all 50 hospitals is 3.15, though CMIs range 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.Why is payer mix important?
Payer mix is health care jargon for the percentage of revenue coming from private insurance versus government insurance versus self-paying individuals. The mix is important because Medicare and Medicaid pay hospitals less than what it costs to treat patients.What is activity based funding?
Activity Based Funding. Activity Based Funding (ABF) is a way of funding hospitals whereby they get paid for the number and mix of patients they treat. If a hospital treats more patients, it receives more funding. Because some patients are more complicated to treat than others, ABF also takes this in to account.What is the purpose of diagnostic related groups?
A diagnosis-related group (DRG) is a patient classification system that standardizes prospective payment to hospitals and encourages cost containment initiatives. In general, a DRG payment covers all charges associated with an inpatient stay from the time of admission to discharge.Why is Case Mix important in evaluating different healthcare providers?
HCFA's most urgent research need in case-mix classification is to determine whether the DRG system is fair to classes of beneficiaries, to individual hospitals, and to classes of hospitals. Resolving this question is important because any problems which exist should be promptly identified and corrected.What is patient case mix?
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 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 CMI nursing home?
Skilled Nursing Homes. CMI has more than 35 years experience in managing and operating Skilled Nursing Facilities. CMI maintains state-of-the-art information management systems to enhance patient care and streamline billing, claims processing, medical records and financial management.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 does CMI mean?

How is severity of illness determined?
To determine the severity of illness score for an individual case, a rater scores each of the seven dimensions into one of four levels of increasing severity by examining data in the patient's medical record following discharge.Why is the CMI for Table 2b higher than the CMI for Table 2a?
A: The CMI increased because volume increased for a MS-DRG with a RW higher than the CMI in table 2A. A: MS-DRG 034 has a higher relative weight because the patient has a major complication/comorbidity which required more resources to treat and manage than patients that do not have a MCC.
