Hierarchical Condition Category (HCC)


Hierarchical Condition Category (HCC) is a risk-adjustment model that is used to estimate future health care costs for patients. It was developed by the Centers for Medicare & Medicaid Services (CMS) in 2004 and is now used by a variety of payers, including Medicare, Medicaid, and commercial insurers.

HCCs are sets of medical codes that are linked to specific clinical diagnoses. Each HCC represents a group of diagnoses with similar clinical complexity and expected annual care costs. The HCC model uses these codes to assign patients a risk score, which is then used to adjust payments to providers and plans.

How does HCC work?

The HCC model is based on the following factors:

  • Diagnoses: The HCC model uses ICD-10-CM codes to identify diagnoses that are associated with increased health care costs.

  • Severity: The HCC model assigns different weights to different diagnoses, depending on their severity. For example, a diagnosis of cancer will have a higher weight than a diagnosis of a common cold.

  • Age: The HCC model takes into account the patient's age, as older patients tend to have higher health care costs.

  • Gender: The HCC model also takes into account the patient's gender, as men and women tend to have different health care needs.

What are the benefits of HCC?

HCC has a number of benefits, including:

  • It helps to ensure that patients with complex medical conditions receive the care they need.

  • It helps to reduce the administrative burden on providers and payers.

  • It helps to promote value-based care by aligning payments with patient outcomes.

What are the challenges of HCC?

HCC also has some challenges, including:

  • It can be difficult to accurately code HCCs.

  • The HCC model is complex and can be difficult to understand.

  • The HCC model may not be accurate for all patients.

What are the latest updates to HCC?

The HCC model is regularly updated to reflect changes in the health care landscape. The most recent update, which was released in 2022, includes a number of changes, including:

  • New HCCs: The update adds 10 new HCCs, including HCCs for obesity, chronic obstructive pulmonary disease (COPD), and dementia.

  • Changes to existing HCCs: The update also makes changes to a number of existing HCCs, including changes to the weights for different diagnoses and changes to the age and gender factors.

Conclusion

HCC is a valuable tool that can be used to improve the efficiency and effectiveness of the health care system. By accurately coding HCCs, providers can help to ensure that patients with complex medical conditions receive the care they need. The HCC model is also being used to promote value-based care by aligning payments with patient outcomes.
