Understanding Medicare Coverage for Zofran

Home » Resources » Understanding Medicare Coverage for Zofran

Zofran, also known by its generic name ondansetron, is a prescription medication commonly used to prevent nausea and vomiting caused by certain medical conditions such as chemotherapy, radiation therapy, and surgery. It belongs to a class of drugs called antiemetics, which work by blocking the action of chemicals in the body that trigger nausea and vomiting.

Medicare Part A

Medicare Part A, also known as hospital insurance, covers inpatient hospital stays, skilled nursing facility care, hospice care, and limited home healthcare services. However, it does not typically cover prescription medications like Zofran when administered outside of a healthcare facility.

Medicare Part B

Medicare Part B, also known as medical insurance, covers outpatient services, including doctor visits, preventive care, and medically necessary medications that are administered in an outpatient setting. While Zofran falls under the category of medically necessary medications, it is important to note that Medicare Part B generally does not cover self-administered prescription drugs, which are typically obtained from a pharmacy and taken at home.

Medicare Part D

Medicare Part D is the prescription drug coverage program offered by private insurance companies approved by Medicare. Part D plans vary in terms of the drugs they cover, formularies, and costs. If you have a standalone Part D plan or a Medicare Advantage plan with prescription drug coverage, you may be eligible for coverage for Zofran. It is crucial to review the specific details of your plan, such as the drug formulary and any coverage restrictions, to determine if Zofran is included.

Medicare Advantage Plans

Medicare Advantage plans, also known as Part C, are an alternative to Original Medicare (Part A and Part B) and are offered by private insurance companies approved by Medicare. These plans typically include all of the benefits of Original Medicare, along with additional coverage options, such as prescription drugs, vision, dental, and hearing services. If you have a Medicare Advantage plan, you should refer to the plan’s formulary to understand if Zofran is covered and the associated costs.

Potential Out-of-Pocket Costs

Medicare beneficiaries should be aware that even if Zofran is covered under their plan, there may still be out-of-pocket costs involved. These costs can include deductibles, copayments, and coinsurance. It is advisable to review your plan’s Summary of Benefits and consult with your insurance provider to get a clear understanding of your potential financial responsibilities.

Alternative Coverage Options

If you find that Zofran is not covered under your Medicare plan or the associated costs are prohibitive, there are alternative coverage options you may explore:

  1. State Pharmaceutical Assistance Programs (SPAPs): Some states offer SPAPs to provide assistance with prescription drug costs. These programs vary by state, so it is important to check eligibility requirements and coverage details specific to your state.
  2. Patient Assistance Programs (PAPs): Pharmaceutical companies often offer PAPs to provide free or discounted medications to eligible individuals who meet specific income criteria. Contact the manufacturer of Zofran or visit their website to explore available assistance programs.
  3. Medicaid: If you qualify for both Medicare and Medicaid, known as dual eligibility, Medicaid may cover Zofran and other prescription medications not covered by Medicare. Check with your state’s Medicaid program for eligibility and coverage information.


In conclusion, understanding Medicare coverage for Zofran can be complex, as it depends on various factors such as the specific Medicare parts, plans, and formularies. While Zofran may be covered under Medicare Part B or Part D, it is important to carefully review your plan’s details and consult with your insurance provider for precise coverage information. Additionally, exploring alternative coverage options like SPAPs, PAPs, and Medicaid can help mitigate out-of-pocket costs for Zofran.
