Medicare Part B does not typically cover the cost of assisted living. Medicare Part B primarily covers medically necessary services, such as doctor visits, outpatient care, and preventive services. Assisted living is considered a non-medical service, and therefore, it is not covered by Medicare Part B. However, there may be other options available to help cover the cost of assisted living, such as long-term care insurance or Medicaid. It's important to review your specific insurance coverage and consult with a financial advisor or insurance specialist to explore your options.
