The influence of the Affordable Care Act-Dependent Care Expansion on insurance coverage among young cancer survivors in California: an updated analysis.

PURPOSE

To assess changes in health insurance coverage for young cancer patients pre- and post- the Affordable Care Act-Dependent Care Expansion (ACA-DCE) implementation in California. Further, we examined differences in insurance coverage by socioeconomic and race/ethnicity.

METHODS

Data were obtained from the California Cancer Registry and Medicaid enrollment files, from 2005 to 2014. We conducted difference-in-difference analyses among 7042 cancer patients aged 22-25 years ("intervention group") and 25,269 aged 26-34 years ("control group"). We also examined the independent and combined effects of race/ethnicity and neighborhood socioeconomic status (nSES) on insurance coverage.

RESULTS

After the ACA-DCE implementation, we observed a 52.7% reduction in the proportion of uninsured and a 35.7% increase in the proportion of privately insured patients. There was also a 17.3% reduction in Medicaid at cancer diagnosis and a 27.5% reduction in discontinuous Medicaid enrollment. However, these benefits were limited to patients of non-Hispanic White, Hispanic and Asian/Pacific Islander race/ethnicity living in higher nSES, with no differences in insurance enrollment among young adults who lived in low nSES or those of Black race/ethnicity.

CONCLUSION

The ACA-DCE broadened insurance coverage for young adults with cancer in California. Yet, only certain subgroups of patients have benefited from this policy.
