Certified Risk Adjustment Coder (CRC)

Which statement is true regarding diagnosis codes and assigned HCCs?

1. All diagnosis codes are assigned an HCC.

2. All chronic illnesses are assigned an HCC.

3. Not all diagnosis codes are assigned an HCC.

4. All acute exacerbations of an acute illness are assigned an HCC.

The correct answer is: Not all diagnosis codes are assigned an HCC.

In the context of risk adjustment coding and Hierarchical Condition Categories (HCCs), it is accurate to state that not all diagnosis codes are assigned an HCC. HCCs are specifically designated for certain conditions that have a significant impact on health outcomes and resource utilization in a patient population, particularly those with chronic diseases. The coding system recognizes that only a subset of diagnoses relates directly to risk adjustment factors influencing payment and reimbursement in Medicare and similar programs. Many diagnosis codes may exist within the coding systems, but only some of them align with the categories established by HCCs. For instance, an acute condition or a minor diagnosis might not have an associated HCC, as the focus is on conditions requiring ongoing management and contributing to risk stratification within health care systems. This distinction is crucial for coders to understand, as it directly impacts the accurate representation of patient risk profiles and the associated financial reimbursement for healthcare services. The other statements oversimplify the relationship between diagnosis codes and HCC assignments. Not all chronic illnesses automatically qualify for an HCC, and acute exacerbations of conditions do not always receive HCC status unless they meet specific criteria. Therefore, recognizing that not all diagnosis codes correspond to an HCC is fundamental to proper coding practices in risk
