What private health plan underwriting asks, and who gets declined
Quick answer
A private health plan application asks about your height and weight, tobacco use, current prescriptions, and whether you have been diagnosed with or treated for a list of conditions in the last 5 to 10 years, including diabetes, heart disease, cancer, COPD, mental health treatment and pregnancy. Healthy applicants are typically approved at the quoted range, for example $175 to $599 a month for a 40-year-old man in Harris County, Texas, against $375 for the cheapest Marketplace Bronze at full price (CMS plan file, August 4, 2026 snapshot). Applicants with a controlled condition are often approved at a higher price or with that condition excluded, and applicants with insulin-dependent diabetes, a recent cancer, heart disease or a current pregnancy are usually declined and belong on the Marketplace, which accepts everyone and covers pre-existing conditions.
A private health plan application asks about your height and weight, whether you use tobacco, what prescriptions you take, and whether you have been diagnosed with or treated for any condition on a list that runs from high blood pressure to cancer, usually looking back 5 to 10 years. A healthy applicant who answers no to the list is typically approved at the quoted range, which for a 40-year-old man in Harris County, Texas is $175 to $599 a month, against $375 for the lowest-priced Marketplace Bronze plan at full price. An applicant with a controlled condition is often approved at a higher price, or approved with that condition written out of the policy. An applicant with insulin-dependent diabetes, a heart condition, a recent cancer or a current pregnancy is usually declined, and for that person the Marketplace, which asks no health questions and covers pre-existing conditions, is the right answer at any price.
That is medical underwriting in three sentences. The rest of this guide walks through the application, how each answer turns into a price, an exclusion or a decline, and how the result compares with 2026 Marketplace prices from the official plan file. Our advisors place both kinds of plan, so this is written from the middle: underwriting suits some households and not others, and you can usually tell which you are before you apply.
First, what underwriting is and why it exists
Marketplace plans sold on HealthCare.gov and the state exchanges are issued to everyone who applies. The insurer must accept you, must charge the same rate as every other person of your age and county, and cannot exclude anything you already have. The price of that promise is that healthy people pay the same premium as sick people, which is why full-price Marketplace premiums look high to a healthy 40-year-old.
Private plans sold outside the Marketplace work the other way. They are not ACA coverage, are not sold on HealthCare.gov, do not qualify for the premium tax credit, and need not cover every essential health benefit. In exchange, the carrier prices each applicant on their own health. Healthy applicants are priced as healthy; everyone else is priced higher, limited, or turned away. Our guide to network types on both markets covers how the plans differ; this one is only about getting approved.
The questions on the application
Applications differ from carrier to carrier, but the shape is consistent. Expect these sections, in roughly this order:
- Height and weight. The carrier converts these to body mass index and most have a maximum, often around 40, above which the application is declined or priced up. A few points over the line can be the difference between the low end of the range and a decline.
- Tobacco and nicotine. Any cigarette, vape, chewing tobacco or nicotine patch use in the past 12 months, sometimes 24. Tobacco users are typically approved at a higher rate. Marketplace plans in most states also charge tobacco users up to 50% more, so this is one question both markets ask.
- Current medications. Every prescription you take, the dose and what it treats. This is the question that catches people. A daily blood-pressure or cholesterol pill is a diagnosis in the carrier's eyes even if you feel perfectly well, and the carrier can check it against a prescription history database.
- The condition list. A yes-or-no list, usually with a 5-year or 10-year lookback, covering heart disease and stroke, diabetes, cancer, COPD and other lung disease, kidney or liver disease, autoimmune conditions such as rheumatoid arthritis, lupus or multiple sclerosis, mental health diagnoses and treatment, substance use treatment, HIV, back and joint problems, sleep apnea, and digestive conditions such as Crohn's disease.
- Pregnancy and planning. Whether anyone on the application is pregnant or, on some forms, expecting to be. A current pregnancy is a decline on nearly every private plan, and maternity is often excluded or limited even for people who are approved.
- Pending care. Whether you have a surgery, test or specialist visit scheduled, or symptoms you have not yet seen a doctor about. A scheduled knee replacement is a decline or an exclusion until it is done and healed.
- Hospital and claims history. Hospital stays, emergency visits and surgeries in the lookback period, and whether you have been declined or rated by another carrier.
Two things surprise people. The carrier usually orders no exam or blood work; it relies on your answers, a prescription-history check and sometimes a short phone interview. And it can check: a condition left off the application that shows up in pharmacy records or a later claim can lead to the policy being rescinded in its first two years. Answer everything the way your medical records would.
What each answer turns into
An underwriter has four tools: approve at the quoted rate, approve at a higher rate, approve with an exclusion rider, or decline. Here is how common situations typically land. Carriers differ, and an advisor who works with several of them can often tell you before you apply which one is likely to say yes.
| Situation | Typical outcome | What it means for you |
|---|---|---|
| No conditions, no prescriptions, BMI in range, non-tobacco | Approved at the quoted range | The low end of the range is within reach for a higher-deductible plan |
| Controlled high blood pressure or high cholesterol on one medication | Often approved, sometimes at a higher rate | Expect the middle of the range rather than the low end |
| Seasonal allergies, mild asthma with an inhaler, past ADHD or anxiety medication | Approved, occasionally with a rider | The carrier may exclude that one condition for a period or permanently |
| Past back or joint injury, fully recovered | Approved with an exclusion rider on that joint or the spine | Claims for that body part are not covered; everything else is |
| Type 2 diabetes controlled with oral medication | Declined by many carriers, rated or excluded by some | Usually the Marketplace is the better home |
| Insulin-dependent diabetes, heart attack, stent or bypass, stroke, COPD | Declined | Marketplace, where it is covered at the standard rate |
| Cancer treated within the last 5 to 10 years | Declined until the carrier's waiting period has passed | Marketplace in the meantime |
| Current pregnancy, or planning one in the next year | Declined if pregnant; maternity often excluded if approved | Marketplace, where maternity is an essential health benefit |
| BMI above the carrier's limit | Declined or rated | Ask the advisor for the limit before applying |
General patterns from the underwriting guides our advisors work with. Every carrier sets its own rules and the underwriter decides each case; nothing in this table is a decision about your application.
An exclusion rider is the outcome people understand least. It removes one condition, or one body part, from the policy. Someone approved with a rider on the left knee is covered for a heart attack, a broken arm or a cancer diagnosis, but not for anything the carrier decides relates to that knee. If the knee problem is behind you, a rider is often a fair trade for a premium well below the Marketplace price. If you expect that knee to need surgery, it is coverage with a hole exactly where the claim will be.
What approval is worth: 2026 prices on both sides
The reason to sit through a health application is the gap between the private range and the full Marketplace price. Here are five large counties for a single non-tobacco applicant, priced from the official 2026 plan file (CMS QHP Landscape PY2026, snapshot August 4, 2026) on the Marketplace side and from the carrier rate tables our advisors quote from on the private side. The Marketplace figure is the lowest-priced Bronze plan at full price, before any tax credit.
| County | Age | Cheapest Marketplace Bronze, full price | Private range, man | Private range, woman |
|---|---|---|---|---|
| Harris County, TX | 40 | $375 | $175 to $599 | $212 to $651 |
| Harris County, TX | 55 | $653 | $376 to $769 | $335 to $729 |
| Hillsborough County, FL | 40 | $478 | $200 to $629 | $236 to $681 |
| Hillsborough County, FL | 55 | $835 | $430 to $837 | $374 to $779 |
| Maricopa County, AZ | 40 | $388 | $172 to $595 | $206 to $644 |
| Maricopa County, AZ | 55 | $678 | $367 to $758 | $324 to $715 |
| Mecklenburg County, NC | 40 | $447 | $155 to $574 | $184 to $616 |
| Mecklenburg County, NC | 55 | $780 | $329 to $711 | $289 to $670 |
| Franklin County, OH | 40 | $397 | $155 to $574 | $177 to $607 |
| Franklin County, OH | 55 | $693 | $329 to $711 | $278 to $656 |
One adult, non-tobacco, monthly. Marketplace: lowest-priced Bronze plan in the county, full price, CMS plan-year 2026 Individual Medical file, snapshot August 4, 2026. Private: starting range for a healthy applicant from the carrier rate tables our advisors quote from, after their usual adjustment; the low end is a higher-deductible plan and the high end a richer one. How we price explains both columns.
Read the table as a healthy applicant and the case for underwriting is plain: a 40-year-old in Mecklenburg County can be quoted from $155 a month against $447 for the cheapest Bronze, and at 55 the private low end in Harris County is a little over half the Marketplace floor. Read it as someone who will be declined and the private columns do not apply to you; your price is the Marketplace column, the same whether you are healthy or not.
Marketplace premiums follow the federal age curve, so the 55-year-old pays about 1.7 times the 40-year-old everywhere in the table. Private prices rise with age too, and the application gets harder to pass, because by 55 more people take a daily medication or have a surgery in their history. Our guides to couples in their 50s and costs at 60 go deeper on that stage.
The tax credit changes the comparison before underwriting does
Before anyone fills in a health application, check whether a tax credit already closes the gap. The 2026 premium tax credit is available to households between 100% and 400% of the federal poverty level, which for one person is $15,650 to $62,600 in the 48 contiguous states, and it cannot be used on a private plan. Here is the same single 40-year-old at two incomes, after the estimated credit:
| County | Full-price Bronze | Benchmark Silver | Bronze at $45,000 | Bronze at $60,000 | Bronze at $70,000 |
|---|---|---|---|---|---|
| Harris County, TX | $375 | $592 | $142 | $280 | $375 |
| Hillsborough County, FL | $478 | $649 | $189 | $328 | $478 |
| Maricopa County, AZ | $388 | $484 | $264 | $388 | $388 |
| Mecklenburg County, NC | $447 | $583 | $223 | $362 | $447 |
| Franklin County, OH | $397 | $538 | $219 | $357 | $397 |
Single 40-year-old, household of one, estimated 2026 premium tax credit under IRS Rev. Proc. 2025-25 and the HHS 2025 poverty guidelines. $45,000 is 288% of the poverty level, $60,000 is 383%, and $70,000 is above the 400% limit, so the credit is zero. The Marketplace sets the final credit.
At $45,000 the after-credit Bronze in Harris County is $142, below the private range for a 40-year-old man. For a healthy applicant the Marketplace wins outright, and the Marketplace plan carries no health questions and no exclusions. At $70,000 the credit is gone, the Bronze is $375, and the private low end is less than half of it, so the health application earns its keep. Our guide to how the 2026 premium tax credit works has the full method, and the price comparison tool runs both columns for your household and ZIP.
How to prepare, and how to avoid a surprise
- List your prescriptions before the call. Name, dose and reason. An application that matches the pharmacy record is approved faster than one corrected later.
- Know your height, weight and the carrier's BMI limit. An advisor can tell you the limit before you apply, which avoids a decline on your record.
- Mention anything on the list, even if it seems minor. A good advisor pre-screens against several carriers' guides and routes the application to the one most likely to approve, or says plainly that the Marketplace is the better home.
- Get any rider in writing before you accept. "Disorders of the lumbar spine" is broader than "the 2021 disc herniation."
- Do not drop Marketplace coverage until the private policy is in force. Outside Open Enrollment, which runs November 1 through January 15 in the HealthCare.gov states, you cannot simply go back if the application is declined.
Who should skip underwriting altogether
The Marketplace is the better choice, usually without needing a private quote, for these groups. Marketplace plans must accept you, cannot exclude a condition, cap out-of-pocket costs at $10,600 for 2026, and cover maternity, mental health and prescriptions as essential health benefits.
- Anyone with insulin-dependent diabetes, heart disease, a stroke history, COPD, kidney disease, an autoimmune condition under treatment, or a cancer diagnosis in the lookback period.
- Anyone pregnant or planning a pregnancy in the coming year, or with a surgery scheduled.
- Anyone under 400% of the poverty level whose after-credit price is already near the private low end; in the counties above, that is most single people earning under about $50,000.
- Anyone under 250% of the poverty level, who also qualifies for cost-sharing reductions that lower a Silver plan's deductible, often to a few hundred dollars. Our guide to choosing a tier explains those.
Private plans fit the household that is healthy, over the credit limit or close to it, and facing a high deductible at full Marketplace price. For that household the application is a short conversation with a large reward. For everyone else it is a detour. Enter your ZIP in the tool, read both columns, and if the private column looks better, talk through the health questions with an advisor before you apply. If income is part of the decision, confirm your poverty-level percentage and any tax-credit figures with your tax professional, because the credit is reconciled on your tax return.
Questions people ask
What health questions does a private health insurance application ask?
Height and weight, tobacco or nicotine use in the past 12 to 24 months, every current prescription, and a yes-or-no list of conditions diagnosed or treated in the last 5 to 10 years: heart disease, stroke, diabetes, cancer, COPD, kidney and liver disease, autoimmune conditions, mental health and substance use treatment, HIV, back and joint problems and sleep apnea. It also asks about pregnancy, scheduled surgery and hospital stays. Most carriers check answers against a prescription-history database rather than ordering an exam.
Can a private health plan deny me for a pre-existing condition?
Yes. Private plans sold outside the Marketplace are medically underwritten and are not ACA coverage, so the carrier can decline the application, charge a higher rate, or approve it with a rider that excludes the condition. Insulin-dependent diabetes, heart disease, recent cancer and a current pregnancy are usually declines. Marketplace plans cannot deny you or exclude a condition, and they cost the same whether you are healthy or not, so anyone with an ongoing condition usually belongs there.
Is a private plan worth the health questions for a healthy person?
Often, when no tax credit applies. In Harris County, Texas a healthy 40-year-old man is typically quoted $175 to $599 a month on private plans against $375 for the lowest-priced Marketplace Bronze at full price in the 2026 plan file; at 55 the range is $376 to $769 against $653. Under 400% of the poverty level the credit can close that gap: at $45,000 the same 40-year-old pays about $142 for the Bronze after the credit, with no health questions. Private plans do not qualify for the credit. Confirm income figures with your tax professional.
