Healthcare costs are skyrocketing—reaching a staggering $4.5 trillion in 2022, according to the CMS. But what’s even more alarming is the impact on healthcare access, a critical determinant of overall health. Limited access doesn’t just inflate costs; it increases mortality rates, putting countless lives at risk. It’s time for a shift. By harnessing data, technology, and innovative solutions, healthcare providers can break this cycle—enhancing patient care while cutting down expenses. Discover how the CMS Health Equity Index is driving this transformation.
We will also explore its aim, why was it developed, and key metrics in measuring healthcare access and quality.
What is the CMS Health Equity Index?
The CMS introduced the Health Equity Index to encourage Part C and Part D health plans to enhance care for vulnerable groups. Launched in 2023, the index aims to promote equity within the U.S. healthcare system. It influences CMS Star Ratings by consolidating various metrics, such as the CAHPS (Consumer Assessment of Healthcare Providers and Systems), into one comprehensive score. Many health plans utilize the Health Equity Index to assess and improve their Star Ratings.
The index evaluates health plan performance on a scale from -1 to +1. Only plans meeting the eligibility criteria are scored, and those performing well are rewarded, driving improvements in healthcare equity.
Aim of the CMS Health Equity Index
The primary objective of the CMS Health Equity Index is to ensure a more equitable distribution of healthcare resources, particularly for vulnerable populations. It seeks to guarantee that factors like gender, geography, or ethnicity do not influence the quality of care individuals receive. Through this index, CMS gathers data on health equity from health plans to promote fair and equal treatment for all patients.
Why Was the Health Equity Index Developed?
The Health Equity Index was established to address persistent healthcare disparities, many of which arise from systemic racism. Historically, minority groups, including Black Americans, have faced unequal access to healthcare. For example, cancer screening rates have shown stark differences between white and Black populations.
CMS developed the index as part of its broader effort through Medicare and Medicaid to reduce these inequities, ensuring everyone receives the same standard of care.
The index also acknowledges the importance of social determinants of health (SDOH), such as age, sexual orientation, and socioeconomic status. These factors play a significant role in healthcare access and outcomes. The Health Equity Index helps health plans better understand the impact of SDOH on member health and direct resources where they are most needed.

Addressing Key Barriers and Enhancing Outcomes
Here, we explore the barriers to healthcare access and quality of care, highlighting how socioeconomic and geographic disparities impact health outcomes.
Healthcare Access
Healthcare access refers to the ability to receive essential medical services like diagnosis, treatment, and disease prevention. Unfortunately, access varies by region, and even with programs like Medicare and Medicaid, many people still struggle to get adequate care.
Some key barriers to healthcare access include:
- Poverty: Many individuals lack the basic resources needed for survival, such as food, shelter, and healthcare.
- Lack of Education: Low health literacy can prevent people from seeking necessary care.
- Economic Instability: Financial struggles can make healthcare unaffordable.
- Racial, Ethnic, and Age Disparities: Minority and older populations often face unequal access to healthcare.
- Geographic Disparities: Rural areas tend to have fewer healthcare providers and limited resources.
Quality of Care
Quality of care is defined as the extent to which healthcare services enhance the chances of achieving favorable health outcomes for both individuals and communities. It is based on evidence-based practices and is vital for achieving universal health coverage. Key components of quality care include:
- Effectiveness: Delivering care based on the best available evidence.
- Person-Centered Care: Providing care tailored to individual needs and preferences.
- Safety: Ensuring that care does no harm to patients.
- Timeliness: Providing care without unnecessary delays.
- Efficiency: Minimizing the waste of healthcare resources.
- Equitability: Delivering care that doesn’t vary in quality due to factors like race or income

Key Metrics in Assessing Healthcare Access and Quality
The CMS Health Equity Index measures healthcare access and quality by using several key metrics that highlight disparities across different populations. These metrics include:
1. Age-Adjusted Ratios: Adjusting for age allows for more accurate comparisons of disease burden and death rates across populations. It accounts for differences in age distribution, providing a clearer picture of health disparities, especially in age-sensitive conditions like cardiovascular disease or cancer.
2. Total Cases per 100k People: This metric standardizes disease cases by population size, making it easier to compare health conditions across different communities. It helps highlight which populations are more heavily affected by certain diseases, like COVID-19 or diabetes, regardless of their population size.
3. Share of Total Cases with Unknown Race/Ethnicity: This metric flags gaps in data related to race and ethnicity. Addressing these gaps is crucial for tackling health disparities, ensuring that resources are directed to groups that might be underrepresented, and promoting more equitable healthcare access.
4. Index Score: A consolidated numerical value that reflects the overall level of health equity within a population. By distilling complex data into a straightforward score, it helps compare healthcare outcomes across groups and assess the impact of policies or programs aimed at improving equity.
5. Percent Share: This shows the percentage of total healthcare outcomes attributed to specific demographic subgroups. It helps identify which groups are experiencing disproportionate health challenges, shedding light on areas that need focused attention.
6. Share of Total Cases: This metric compares the actual number of cases in a group to what would be expected based on the group’s population size. It helps track disparities in health outcomes over time, making it easier to pinpoint where inequities exist and where interventions are needed.
7. Population Share: This measures how much of the total population a specific demographic group makes up. It’s a key tool for ensuring that healthcare interventions and resources are distributed fairly, based on the makeup of the population.
8. Percent Rate: Expressing health outcomes as a percentage allows for easier comparisons across groups. It’s useful for monitoring disparities in healthcare access, treatment outcomes, and resource use.
9. Relative Inequity: This metric quantifies the differences in health outcomes or access between demographic groups. It’s central to identifying which populations are facing greater disadvantages and informs strategies to reduce these gaps and ensure fairness in healthcare.
Together, these metrics form a comprehensive approach to assessing healthcare access and quality, helping to identify disparities and guide efforts toward more equitable healthcare for all.
Challenges of the CMS Health Equity Index
While the CMS Health Equity Index is a useful tool for identifying disparities in healthcare, its implementation faces several obstacles. One major challenge is incomplete data reporting, which makes it difficult for CMS to accurately identify inequities when all necessary information isn't available. Additionally, there is a lack of standardized methods for collecting health equity data across various programs, leading to inconsistencies that hinder a full understanding of healthcare disparities.
Limited data availability can also obstruct a thorough assessment of patients' health conditions, exacerbating inequities. Moreover, implicit biases in data collection and analysis can further affect the accuracy of the Health Equity Index.
Conclusion
The CMS Health Equity Index is essential for advancing healthcare access and quality across diverse populations. By focusing on metrics that highlight healthcare disparities, like age-adjusted ratios and the share of cases with unknown race and ethnicity, the index uncovers inequities and guides targeted interventions. Recognizing social determinants of health, it ensures that factors such as socioeconomic status and geographic location are included in healthcare strategies.
As healthcare spending continues to rise, addressing these disparities becomes increasingly important. The CMS Health Equity Index motivates health plans to improve care for vulnerable populations while holding them accountable through its impact on CMS Star Ratings. By providing critical data for informed decision-making, the index aims for a more equitable healthcare system, where everyone has access to quality care, ultimately working towards a healthier society for all.
