Objective:

To understand the effects of reduced Medicaid retroactive eligibility on financial burdens and access to care for patients with newly diagnosed gastrointestinal cancer.

Key Findings:
  • 22,342 patients identified, with 1,553 (6.9%) meeting retroactive eligibility criteria, highlighting a significant portion of patients affected.
  • Mean charges during the first 90 days of enrollment were $140,712, with Medicaid covering $20,867, indicating substantial out-of-pocket expenses.
  • Traditional enrollees could face additional costs of $9,766 to $72,559; expansion enrollees $16,472 to $114,885 under the OBBBA, underscoring the financial burden.
Interpretation:

Reducing retroactive eligibility may significantly burden low-income cancer patients with unexpected medical expenses, increasing financial toxicity and jeopardizing access to necessary care.

Limitations:
  • Potential misclassification of patients due to lack of application date in Medicaid data, which could lead to underestimating the number of affected individuals.
  • Findings may not be generalizable to states with different retroactive coverage policies.
Conclusion:

Changes in Medicaid retroactive eligibility could adversely affect low-income cancer patients, necessitating awareness and timely enrollment to mitigate financial risks.
