Abstract
BACKGROUND
Medicare coverage excludes some levels of substance use disorder (SUD) care, such as intensive outpatient and residential treatment. Expanding access to SUD treatment could increase Medicare spending. However, these costs could be offset if SUD treatment resulted in cost savings from reducing SUD-related medical events and SUD-related medical comorbidities.
METHODS
This study estimated cost savings from expanding access to SUD treatment for persons with opioid use disorders (OUD) using three methods. First, we compared total Medicare fee-for-service spending on individuals with OUD and no treatment with OUD medications (MOUD) to Medicare spending on individuals without OUD after matching on age/sex/Medicare-Medicaid eligibility status. Second, we compared Medicare spending on individuals with OUD who received MOUD to spending individuals with OUD who did not receive MOUD. Third, we determined OUD-attributable Medicare spending for comorbid physical and mental conditions with a strong association with OUD.
RESULTS
Beneficiaries with OUD but no MOUD totaled $15.8 billion more than beneficiaries without OUD. Beneficiaries with OUD but no MOUD totaled $12.1 billion more than individuals with OUD and MOUD. Lastly, Medicare spending on OUD-attributable comorbidities was $4.7 billion if all medical and mental health comorbidities were included and $3.0 billion with only medical comorbidities. The totals could be 1.7 times higher if Medicare Advantage enrollees were included.
CONCLUSION
Expanding Medicare coverage of appropriate levels of care could improve access to effective treatment and reduce the costs associated with untreated OUD. This will likely result in substantial Medicare cost savings.
