  • I just found out that I’m pregnant, and I do not have health insurance. Can I enroll in a plan through the health insurance Marketplace?

    FAQs

    Yes. However, while you are still pregnant, you may only enroll during an Open Enrollment period, which is typically from November through mid-January. Once enrolled, your plan will be required to cover maternity services. You may also qualify for a premium tax credit and/or a cost-sharing reduction, depending on your family income and your eligibility for employer coverage. After the baby is born, you can sign up for health insurance and add the baby to your plan, no…

  • What services do plans have to cover for pregnancy?

    FAQs

    Federal laws require many employer-sponsored plans and all ACA-compliant individual insurance plans, including those available through the Marketplaces, to cover maternity services, including pregnancy, childbirth, and newborn care. Cost sharing may apply to some maternity services. Most private plans also must cover prenatal visits and screenings, folic acid supplements, tobacco cessation counseling and interventions, and breastfeeding services such as pumps and lactation consultations without any cost-sharing because they are considered preventive services. All state Medicaid…

  • Does my health plan have to cover all birth control methods with a prescription? Do I have to pay a copay?

    FAQs

    Most employer plans and all Marketplace plans must cover at least one form of all FDA-approved, granted, or cleared birth control (“contraceptive”) services and supplies for women, without cost sharing. This includes sterilization services, insertion and removal of long-acting reversible birth control methods, and follow-up services. While some birth control methods are available over the counter without a prescription, plans typically require a prescription to trigger coverage. Though it is up to an insurer’s discretion,…

  • I heard that plans have to cover preventive services without cost sharing. Does this include every preventive service and are there any limitations or exceptions?

    FAQs

    Most health plans, including Marketplace plans, are required to cover a wide range of preventive services and may not impose cost-sharing (such as deductibles, copayments, or co-insurance). The ACA requires private plans to cover services under four broad categories: Evidence-based screenings and counseling Routine immunizations Childhood preventive services Preventive services for women So long as the preventive service is performed by an in-network provider, is not billed separately from the office visit, and is the main…

  • What is a Catastrophic health plan?

    FAQs

    A “Catastrophic plan” is a qualified health plan offered on or off the Marketplace that covers the “essential health benefits.” While Catastrophic plans have lower premiums than other qualified health plans, they also have the highest level of cost sharing allowable for an ACA-compliant plan. For 2026, the annual deductible for covered services in a Catastrophic plan is $10,600 for an individual or $21,200 for a family. The plan does not have to cover more…

  • I’m covered on my parents’ health plan, but I’m turning 26 soon and won’t be eligible to stay on their plan. What are my options?

    FAQs

    You should act now to review your coverage options and sign up for new coverage. If your parents get their insurance through an employer that has at least 20 workers, you may be able to continue that coverage (known as COBRA) for up to 3 years, but it will likely be much more expensive than other coverage options. If you are employed, find out if your employer offers health insurance and if you qualify. If…

  • I’m covered under my parents’ plan, and I’m pregnant. Will my parents’ plan cover my prenatal care and delivery?

    FAQs

Cost sharing may apply to some maternity services. Most private plans also must cover prenatal visits and screenings, folic acid supplements, tobacco cessation counseling and interventions, and breastfeeding services without any cost-sharing because they are considered preventive services. Some health plans are not required to cover all…

  • Can I be covered under my parent’s health plan if I’m married?

    FAQs

    Yes. You can stay on your parents’ plan until you turn 26 if they have coverage through work, or until the end of the year you turn 26 if they have Marketplace coverage. Being married does not affect your eligibility to be covered under your parents' plan.

  • I’m covered under my parents’ health insurance plan, but I’m moving to another state. Can I remain covered on my parents’ plan?

    FAQs

    Yes, you are eligible to stay on your parents’ plan up to age 26 if they have coverage through a job, or until the end of the year you turn 26 if they have Marketplace coverage, regardless of where you live. However, your parents’ health plan probably has a network of participating health care providers, and it may be difficult for you to find in-network providers when you are living in another state. If you…

If your parents get their insurance through their employer, you have…
