Does Medicare Cover Addiction Treatment?

Medicare generally does cover substance abuse rehab, but it may not cover all aspects of addiction treatment. Original Medicare Part A covers inpatient care for up to 190 days.1 The cost depends on your plan. You typically pay your deductible for the first 60 days and then cover a portion of the cost if you stay longer.

Costs vary further for outpatient care, depending on the type of treatment you need. Medicare mental health coverage is also included as required by the Affordable Care Act (ACA). It covers therapy for co-occurring disorders like anxiety, depression, and other mental health disorders.
