How to Figure Out What Health Insurance Covers
What does your health insurance plan cover?
Health insurance helps pay for doctor visits, tests, medicines, and hospital care. Every plan is different, so it is important to know what your plan will cover before your child begins treatment.
Review your insurance plan documents to understand:
- Benefits coverage: What services the plan will pay for
- Provider networks: Which doctors and hospitals are considered to be in network for your plan. Your insurance company has an agreement with the in-network providers. You usually pay less to see them. Out-of-network providers do not have a contract with your insurance company, so you may pay more for care.
- Possible out-of-pocket costs: What you may have to pay yourself

Start with your plan documents
Your insurance company or employer should give you written information about what your plan covers. These documents may include:
- Summary plan description (SPD): An overview of what the plan provides and how it works
- Evidence of coverage (EOC): A detailed list of benefits and costs
- Summary of benefits and coverage (SBC): A summary of the covered services and common costs
If you do not have these documents, request copies. They may also be available through an online patient portal.
What to ask your care team
Before talking with the insurance company, talk with your child’s care team. They can help you understand what care your child will need so that you can ask the insurance company the right questions.
Write notes or use a notebook. This will help you stay organized as treatment continues.
At the time of diagnosis
Ask your care team:
- What illness does my child have?
- What tests and procedures are needed?
- Where will these tests and procedures take place?
- Which providers will be involved?
During treatment
Your insurance company may ask for details about your child’s treatment plan.
Ask your care team:
- What is the treatment plan and timeline?
- When will these treatments happen?
- Where will they take place?
- Who will provide the care?
- Will my child need home health care during or after treatment?
Prescription medicines
Ask your care team:
- Which medicines are in the treatment plan?
- Will my child need medicines for side effects or pain?
- How long will they need these medicines?
- Are there safe generic options for these medicines?
Home health care
Some children need care at home while recovering. Insurance plans may cover some of these costs.
Ask your care team:
- What care will my child need at home?
- Will my child need a nurse or special caregiver?
- What equipment will we need?
- How long will this care be needed?

What to ask your insurance company
Once a treatment plan is in place, contact your insurance company. Ask if your child can be assigned a case manager or patient advocate. This person can help guide you through the process, explain coverage rules, and answer questions.
Questions to ask your insurance plan
- Where can my child receive care and who can give it?
- Confirm if the hospital, doctors, and specialists are in network.

- Are referrals or pre-approvals required?
- Some plans require a referral from your child’s primary care provider.
