The Federal Trade Commission is warning health-plan marketers about advertising that makes limited coverage sound like comprehensive insurance. For people shopping before open enrollment, the first decision is identifying what the product actually pays for.

FTC staff sent warning letters to 25 marketers and lead generators on October 29. The agency says the letters do not allege wrongdoing by their recipients. They flag misleading claims about benefits, costs and promised cash rewards, including pitches that present limited-benefit products as major medical insurance.

A low monthly payment, a provider network or an insurance-looking card cannot answer the coverage question. The written policy and benefit schedule can.

Three products with different jobs

Marketplace health plans cover 10 categories of essential health benefits, including hospital care, emergency services, prescription drugs, maternity care and mental health treatment. Those categories establish a coverage floor. They do not mean every treatment is free: deductibles, copayments and other cost sharing generally apply, and specific services can vary with state requirements and the plan.

Limited-benefit insurance pays according to a narrower promise. Michigan's insurance regulator describes accident policies that pay for covered accidents, specified-disease policies that pay for named illnesses, and hospital indemnity policies that provide cash benefits during covered hospital stays. These products are intended to supplement comprehensive insurance.

A fixed payment can leave a substantial bill unpaid. Michigan gives an example of a hospital indemnity policy paying $100 per day. That figure describes the policy's benefit, not the price of the hospital's services or a guarantee that the remaining charges are covered. Check the actual contract for its payment amounts and qualifying events.

Medical discount plans work differently again. Members obtain discounts from participating providers and remain responsible for the discounted charges. Florida's consumer guidance explains that these plans are not health insurance, even when members receive cards resembling insurance cards.

Read the payment promise and the exclusions

Start with the product's full name, the insurer or program operator, and the written description of benefits. A sales pitch mentioning hospital access does not explain how much the product pays when someone is hospitalized.

The Texas Department of Insurance warns that alternative products may exclude preexisting or chronic conditions, impose waiting periods, limit payments or require association membership dues. Its guidance also notes that some plans examine medical history after a costly claim and may deny it based on a preexisting condition. The terms of the specific product determine those restrictions.

For a discount card, confirm participation directly with the doctors or facilities you expect to use before enrolling or paying fees. A network label alone leaves open whether those providers participate and what they will charge. Texas notes that a discount program may use the term PPO while still leaving members responsible for the full discounted cost.

Compare the documents before the premium

For comprehensive health coverage, ask for the Summary of Benefits and Coverage. This standardized document helps compare benefits and costs across plans. Marketplace shoppers can find its link on each plan page when previewing prices and comparing choices after an application.

The summary includes coverage examples for diabetes care and childbirth. Use the same example across the plans under consideration to see how their cost sharing differs. It is a more informative comparison than placing two monthly premiums side by side while ignoring what each product covers.

Keep the actual policy or certificate alongside the summary. If a seller supplies only an advertising brochure or a benefit schedule for a limited product, establish that product's coverage category before treating its price as comparable to comprehensive insurance.

Use the official enrollment route

The FTC's October 29 consumer alert recommends starting at HealthCare.gov or calling the Marketplace at 1-800-318-2596. It warns that paid search results and social-media ads can also contain misleading pitches or impersonation.

The agency's warning-letter template addresses false government or insurer affiliations as well as misleading coverage claims. An ad's official-looking design does not establish an affiliation. Misleading offers and illegal robocalls can be reported at ReportFraud.ftc.gov.
