CDIP Exam Dumps : Certified Documentation Integrity Practitioner

Combination codes are used to classify two diagnoses, a diagnosis with a manifestation, or a diagnosis with an associated complication. A complication is a condition that arises during the hospital stay that prolongs the length of stay by at least one day in approximately 75 percent of cases1. Complications may affect payment and severity of illness and risk of mortality classifications. Examples of combination codes that include a diagnosis with an associated complication are:

• I50.23 Acute on chronic systolic (congestive) heart failure
• K57.21 Diverticulitis of large intestine with perforation and abscess with bleeding
• O34.211 Maternal care for incompetent cervix with cerclage, first trimester

A diagnosis that is an integral part of a disease process is not a valid option for combination codes, because it does not represent a separate or additional condition that needs to be coded. For example, chest pain is an integral part of acute myocardial infarction and does not require a separate code.

A diagnosis with an associated procedure is not a valid option for combination codes, because procedures are coded separately from diagnoses using ICD-10-PCS codes. For example, appendicitis with appendectomy is not a combination code, but rather two codes: one for the diagnosis (K35.80 Acute appendicitis without perforation or gangrene) and one for the procedure (0DTJ4ZZ Resection of appendix, percutaneous endoscopic approach).

A diagnosis with a sequelae or late effect is not a valid option for combination codes, because sequelae or late effects are coded separately from the original condition using the appropriate code from category B90-B94 Sequelae of infectious and parasitic diseases or category I69 Sequelae of cerebrovascular disease, followed by the code for the specific condition2. For example, hemiplegia following cerebral infarction is not a combination code, but rather two codes: one for the sequelae (I69.351 Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side) and one for the original condition (I63.9 Cerebral infarction, unspecified).

A high physician agreement rate can be evidence of physician-hospital alignment because it indicates that the physicians are supportive of the clinical documentation integrity (CDI) program and its goals, and that they are willing to provide accurate and complete documentation in response to CDI queries. A high physician agreement rate also reflects a positive relationship and communication between the CDI team and the physicians, as well as a mutual understanding of the benefits of CDI for patient care, quality reporting, and reimbursement.

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.
