Medicare Coverage for Esketamine: Exploring the Benefits and Eligibility

Home » Resources » Medicare Coverage for Esketamine: Exploring the Benefits and Eligibility

Esketamine, a derivative of ketamine, is a breakthrough treatment for individuals suffering from treatment-resistant depression (TRD). Unlike traditional antidepressants, esketamine works by targeting the glutamate system in the brain, providing rapid relief to those who have not responded to other forms of treatment. Due to its effectiveness, esketamine has garnered significant attention in the medical field.

Medicare Coverage for Esketamine

Medicare, a federal health insurance program primarily for individuals aged 65 and older, also covers certain younger individuals with disabilities. When it comes to esketamine, Medicare coverage is available, but specific conditions must be met to qualify for reimbursement.

  1. Medicare Part B Coverage: Esketamine, when administered in a physician’s office or a supervised healthcare setting, is covered under Medicare Part B. This means that the drug itself, along with the necessary administration and monitoring services, may be eligible for reimbursement.
  2. Medical Necessity: To qualify for Medicare coverage, esketamine treatment must be deemed medically necessary. This typically requires documentation from a healthcare provider demonstrating that the individual has been diagnosed with TRD and has not responded adequately to other antidepressant treatments.
  3. Coverage Limitations: Medicare may have specific guidelines and limitations on the frequency and duration of esketamine treatment. It is crucial to consult with your healthcare provider and review your Medicare plan for detailed information regarding coverage limitations.

Eligibility Criteria for Medicare Coverage

To be eligible for Medicare coverage for esketamine, individuals must meet certain criteria. Here are the key factors to consider:

  1. Medicare Enrollment: You must be enrolled in Medicare Part B, as esketamine coverage falls under this particular part of the program.
  2. Diagnosis of Treatment-Resistant Depression: A diagnosis of treatment-resistant depression is essential. This means that you have tried at least two different antidepressant medications, and your depression has not significantly improved.
  3. Treatment Plan Documentation: Your healthcare provider must document that other treatment options have been attempted without success, establishing the medical necessity of esketamine treatment.
  4. Physician Supervision: Esketamine treatment must be administered under the supervision of a healthcare professional in a certified healthcare setting.


Understanding the coverage and eligibility criteria for esketamine under Medicare is crucial for individuals seeking effective treatment for treatment-resistant depression. By meeting the necessary conditions and working closely with your healthcare provider, you can explore the potential benefits of esketamine and access the coverage you need.

Remember, every individual’s situation may vary, so it is advisable to consult with your healthcare provider and review your specific Medicare plan for personalized information regarding coverage and eligibility.
