CC/MCC exclusion list

The CC/MCC exclusion list is a crucial component of healthcare revenue cycle management (RCM) that plays a significant role in the accurate and appropriate reimbursement of healthcare services. CC/MCC stands for Complication or Comorbidity/Major Complication or Comorbidity, and the exclusion list refers to a specific set of diagnoses that are excluded from being considered as CCs or MCCs for the purpose of Medicare Severity Diagnosis Related Group (MS-DRG) assignment.

To understand the CC/MCC exclusion list, it is essential to grasp the concept of CCs and MCCs. In the context of RCM, CCs and MCCs are additional diagnoses that indicate the presence of significant comorbidities or complications during a patient's hospital stay. These diagnoses are used to adjust the severity of a patient's condition and determine the appropriate reimbursement level for the healthcare services provided.

The CC/MCC exclusion list is designed to ensure that certain diagnoses, despite being clinically significant, are not considered as CCs or MCCs for MS-DRG assignment. This exclusion list is periodically updated by the Centers for Medicare and Medicaid Services (CMS) to reflect changes in medical practice and the evolving understanding of diseases and conditions.

To better understand the CC/MCC exclusion list, it is important to differentiate between CCs, MCCs, and excluded diagnoses.CC (Complication or Comorbidity): A CC is a secondary diagnosis that represents a condition that coexists with the primary diagnosis and affects the patient's treatment and length of stay. CCs are used to adjust the MS-DRG assignment and increase the reimbursement level. Examples of CCs include diabetes, hypertension, or chronic obstructive pulmonary disease (COPD).

MCC (Major Complication or Comorbidity): An MCC is a more severe condition than a CC and has a greater impact on the patient's treatment and resource utilization. MCCs also influence the MS-DRG assignment and result in higher reimbursement. Examples of MCCs include acute myocardial infarction, sepsis, or respiratory failure.

Excluded Diagnoses: Excluded diagnoses are those that, despite being clinically significant, are not considered as CCs or MCCs for MS-DRG assignment. These diagnoses are listed in the CC/MCC exclusion list and are not used to adjust the severity level or reimbursement. Excluded diagnoses may include certain conditions that are considered inherent to a specific procedure or diagnosis, or those that are not likely to affect the treatment or resource utilization significantly.

The CC/MCC exclusion list includes various diagnoses that are excluded from being considered as CCs or MCCs for MS-DRG assignment.

Here are a few examples of diagnoses commonly found on the exclusion list:

1. Diabetes without Complications: While diabetes is typically considered a CC, the exclusion list may exclude diabetes without complications from being considered as a CC or MCC. This exclusion acknowledges that uncomplicated diabetes does not significantly impact the treatment or resource utilization.

2. Hypertension: In some cases, hypertension may be excluded from being considered as a CC or MCC. This exclusion recognizes that hypertension, without any associated complications or organ damage, may not substantially affect the patient's treatment or resource utilization.

3. Chronic Obstructive Pulmonary Disease (COPD) without Acute Exacerbation: COPD is often considered a CC or MCC when it is accompanied by an acute exacerbation. However, if the patient's COPD is stable without any acute exacerbation during the hospital stay, it may be excluded from being considered as a CC or MCC.

It is important to note that the CC/MCC exclusion list is subject to periodic updates by CMS. Therefore, it is crucial for healthcare providers, coders, and RCM professionals to stay updated with the latest version of the exclusion list to ensure accurate coding, billing, and reimbursement.

In healthcare revenue cycle management, the CC/MCC exclusion list plays a vital role in accurately determining the severity of a patient's condition and appropriate reimbursement for healthcare services. By excluding certain diagnoses from being considered as CCs or MCCs, the exclusion list ensures that only clinically significant conditions that significantly impact treatment and resource utilization are used for MS-DRG assignment.

Understanding the CC/MCC exclusion list is essential for healthcare providers, coders, and RCM professionals to ensure compliance with coding guidelines and optimize reimbursement. Staying updated with the latest version of the exclusion list is crucial to avoid coding errors, claim denials, and potential financial losses.
