How Medical Underwriting Works When You Apply for a Private Plan

Why private plans ask about your health

A private, medically underwritten plan prices your coverage on your age, zip code and health, not on your income. That is the whole reason it can cost less than a full-price Marketplace plan for a healthy person, and why it can start on the first of any month if approved, instead of waiting for January. The price of that flexibility is underwriting: before the insurer agrees to cover you, it reviews your health history and decides whether to offer a policy and on what terms.

Marketplace plans work the other way. By law they cannot ask about your health, so everyone in a rating area is pooled together and priced the same way, healthy or not. That guarantee is valuable if you have a serious condition. For everyone else it comes with costs that keep growing:

• 2027 rate increases. KFF's August 2026 review of proposed 2027 filings found a median requested Marketplace increase of about 15 percent, on top of a steep rise for 2026. See why your premium went up.
• The subsidy cliff. For 2027 the tax credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two, $109,280 for three and $132,000 for four. One dollar over and you pay full price.
• Repaying the credit at tax time. If you take an advance credit and your final income lands above the line, you repay the entire advance credit when you file.
• Narrow networks. Many Marketplace plans are HMOs or EPOs that pay nothing out of network outside an emergency.
• A $12,000 ceiling. The 2027 out-of-pocket maximum can reach $12,000 for one person or $24,000 for a family.
• One window a year. Open enrollment for 2027 runs November 1, 2026 to January 15, 2027, with December 15 the deadline for a January 1 start.

Underwriting is how a private plan avoids those trade-offs for people who qualify. Here is what it actually involves.

What the application asks

The health section is a list of yes-or-no questions, usually followed by detail questions when you answer yes. Expect to be asked about:

• Diagnoses and treatment within a set number of years, such as heart conditions, cancer, diabetes, stroke, lung disease, kidney or liver disease, and mental health or substance use treatment.
• Current prescriptions, including the drug name, dose and what it treats.
• Height and weight, and whether you use tobacco or nicotine.
• Any test, referral, surgery or hospital stay that has been recommended but not yet done.
• Pregnancy, for every applicant it applies to.

Every person you want on the policy is asked the same questions, so a spouse's or child's history counts as much as yours. The look-back period and the exact wording differ by plan, which is why I read the questions with you on a call before anything is submitted.

What happens after you apply

1. Your answers are reviewed. Many applications are scored on the spot against the insurer's guidelines.
2. Your answers are checked. With your signed authorization, many insurers pull a prescription history report to confirm the medications you listed.
3. Follow-up, if needed. If something needs explaining, the insurer may call you for a short phone interview or request records from your doctor.
4. A decision. You receive an offer, an offer with conditions, or a decline.

The four outcomes

• Approved as applied. You get the plan and price you applied for.
• Approved with an exclusion. The insurer offers coverage but excludes a specific condition or body part, sometimes permanently and sometimes for a set period.
• Approved on different terms. Some plans offer a different rate class or plan option instead of the one you chose.
• Declined. The insurer will not offer that applicant a policy.

Being honest about these outcomes matters. Underwritten plans can decline applicants, and they can exclude pre-existing conditions. If you have a significant health condition, the Marketplace is the guaranteed option, and I will tell you so on the first call instead of sending you through an application that is unlikely to go your way. Private plans are not ACA Marketplace plans, and their benefits and pre-existing condition rules vary by plan. For a deeper look at how conditions are handled, read private health insurance and pre-existing conditions.

How long it takes

For a healthy applicant with a short medication list, a decision can come back the same day, sometimes within minutes. When the insurer orders a phone interview or medical records, it usually takes several days to a couple of weeks, and the clock depends partly on how fast your doctor's office answers. Coverage starts on the first of a month after approval and your first payment, so the practical rule is to apply two to four weeks before the date you want coverage to begin.

If you are declined

A decline from one private plan is not the end of the road, but it does change the plan:

• Another underwritten plan may say yes. Guidelines differ, and a condition one insurer declines another may accept with an exclusion.
• The Marketplace cannot turn you down. It cannot refuse you or charge you more because of a health condition, as HealthCare.gov explains. You do need to enroll during open enrollment or a special enrollment period.
• A decline does not open a special enrollment period. This is the reason not to cancel the coverage you already have until a new policy is approved and active.
• Split the household. If one family member is declined, the others can often still take a private plan while that person enrolls in a Marketplace plan.

How to make underwriting go smoothly

• Answer completely and accurately. A wrong answer, even an innocent one, can lead to a denied claim or a rescinded policy later. That is far worse than a decline today.
• Have your medication list ready, with doses and the reason for each one.
• Know your dates. When were you diagnosed, last treated, last seen? Approximate dates slow things down.
• Finish pending tests first. An open workup usually means the insurer waits for results, so it is often better to apply once you have them.
• Keep current coverage in place until you have an approval letter, a start date and a paid first premium.
