AHIMA CDIP Exam With Confidence Using Practice Dumps

CMI is a metric that reflects the diversity, complexity, and severity of the patients treated at a healthcare facility, such as a hospital. CMI is used by CMS to determine hospital reimbursement rates for Medicare and Medicaid beneficiaries. CMI is calculated by adding up the relative MS-DRG weight for each discharge, and dividing that by the total number of Medicare and Medicaid discharges in a given month and year. Higher CMI values indicate that a hospital has treated a greater number of complex, resource-intensive patients, and the hospital may be reimbursed at a higher rate for those cases.

However, CMI is not the best measure of CDI performance, because it is influenced by many factors beyond CDI efforts, such as patient population, coding accuracy, documentation specificity, patient comorbidities, high volumes of highly weighted DRGs, and annual updates to relative MS-DRG weights. Therefore, measuring CMI over time with a focus on particular documentation improvement areas in addition to the overall CMI can provide a more comprehensive and meaningful assessment of CDI performance. For example, CDI programs can track CMI changes for specific DRGs, clinical conditions, or service lines that are targeted for documentation improvement initiatives. This can help identify the impact of CDI interventions on documentation quality, accuracy, and completeness.

A. Over time with a focus on high relative weight (RW) procedures that impact these procedures on overall CMI. This is not the best way to measure CMI as a metric of CDI performance, because it may not reflect the true complexity and severity of the patients treated at the facility. Focusing only on high RW procedures may overlook other documentation improvement opportunities for lower RW procedures or medical cases that may also affect patient outcomes, quality indicators, and reimbursement.

C. Month-to-month and focus on patient volumes to determine the raise the overall CMI. This is not a valid way to measure CMI as a metric of CDI performance, because patient volumes do not directly affect CMI. CMI is calculated by dividing the total relative weights by the total number of discharges, so increasing patient volumes will not necessarily raise the overall CMI unless the relative weights also increase.

D. Month-to-month to show CMI variability as a barometer of a specific month. This is not a reliable way to measure CMI as a metric of CDI performance, because month-to-month variations in CMI may be due to random fluctuations or seasonal effects that are not related to CDI efforts. Measuring CMI over a longer period of time can provide a more stable and accurate picture of CDI performance.

According to the AHIMA CDIP Exam Preparation Guide, the adjusted case mix index (CMI) is a measure that demonstrates the relative severity and complexity of patients treated in a hospital, and is used to evaluate the financial impact of a hospital’s clinical documentation integrity (CDI) program1. The adjusted CMI is calculated by multiplying the unadjusted CMI by a factor that accounts for the percentage of Medicare patients in the hospital2. The higher the adjusted CMI, the higher the expected reimbursement per patient, and the more effective the CDI program is assumed to be3. The other options are not correct because they do not measure the severity and complexity of patients or the financial impact of CDI. Hospital acquired conditions (HACs) are conditions that are not present on admission and are considered preventable by CMS, and may result in reduced reimbursement or penalties4. The program for evaluating payment patterns electronic report (PEPPER) is a report that provides hospital-specific data on potential overpayments or underpayments for certain services or diagnoses, and helps identify areas of risk or opportunity for improvement. Present on admission (POA) indicators are codes that indicate whether a condition was present at the time of admission or acquired during the hospital stay, and affect the assignment of DRGs and HACs. References:

An Excludes 2 note in ICD-10-CM indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes 2 note appears under a code, it is acceptable to use both the code and the excluded code together to completely describe the condition. For example, under code R05 Cough, there is an Excludes 2 note for whooping cough (A37.-). This means that a patient can have both a cough and whooping cough at the same time, and both codes can be used together to capture the full clinical picture.
