Ebrief Lander - December 2025 OIG Work Plan Updates

The HHS Office of Inspector General doesn’t update its Work Plan lightly, and even a small number of additions can carry significant compliance implications. 

In December 2025, the OIG introduced new and recurring focus areas that touch some of healthcare’s most scrutinized programs: Medicaid eligibility, Medicare home health payments, and Part B drug reimbursement. While these reviews may appear routine, they align closely with historical enforcement trends tied to documentation gaps, coding practices, and payment accuracy. 

In this overview, we break down: 

  • Why Medicaid eligibility verification—particularly citizenship and immigration status—remains a federal priority 
  • What the OIG is analyzing in home health claims with comorbidity adjustments 
  • How ASP-to-AMP comparisons continue to shape Medicare Part B drug payment oversight 
  • What these focus areas mean for compliance, audit, and reimbursement teams in 2026
