What Can End Your Coverage, and What Cannot Undo It

Ending coverage going forward and unwinding it backwards are two different acts under two different rules. One has six listed exceptions. The other has one.

Key takeaways

  • Undoing coverage backwards and ending it forward are separate acts under separate rules, and only one of them has a six-item list of permitted grounds.
  • A rescission is defined as a cancellation with retroactive effect, and it is barred except for fraud or an intentional misrepresentation of material fact, with at least 30 days advance written notice.
  • The regulation's own worked example concludes that an inadvertent omission on a health questionnaire is not a ground to rescind.
  • An insurer must renew coverage at the option of the sponsor or the individual, and claims cost and health status are not among the six grounds for nonrenewal.
  • Discontinuing a product requires at least 90 calendar days written notice and an offer of other coverage; leaving a market requires 180 days and carries a five-year bar on returning.
  • The rescission rule reaches grandfathered coverage and reaches self-insured group coverage; the renewal rule does neither, so establish which regime applies before quoting either.

Answer first: forward and backward are different acts

Losing coverage feels like one event. In the rules it is two, and they are governed separately.

Ending coverage going forward is nonrenewal or discontinuance. An insurer may do it, and the rule that permits it lists six grounds and nothing else.

Unwinding coverage backwards is a rescission. That is barred outright except in one circumstance, and the bar applies to insured and self-insured group coverage alike.

The regulation defines the backward act rather than leaving it to argument. A rescission is a cancellation or discontinuance of coverage that has retroactive effect.

The single exception is narrow. It requires an act, practice or omission that constitutes fraud, or an intentional misrepresentation of material fact, as prohibited by the terms of the plan or coverage.

Even then, at least 30 days advance written notice has to reach each affected person before coverage may be rescinded.

What a rescission is, and what it is not

The definition is short and it comes with two illustrations, which is unusual and useful.

A cancellation that treats a policy as void from the time of enrollment is a rescission. So is a cancellation that voids benefits paid up to a year before the cancellation.

Four things are then carved out of the definition. A cancellation with only a prospective effect is not a rescission at all.

Nor is a retroactive cancellation to the extent it is attributable to a failure to timely pay required premiums or contributions, including continuation premiums.

Nor is one initiated by the individual or an authorized representative, provided the sponsor, employer, plan or insurer does not directly or indirectly influence that decision, retaliate, interfere, coerce, intimidate or threaten.

Nor is one initiated by an Exchange under the Exchange termination rule, apart from one specified branch of it.

The questionnaire example the regulation prints

On a subject where a form full of health questions decides access, the regulation supplies its own worked example, and it is worth reading verbatim in substance.

An individual seeks enrollment in an insured group health plan whose terms permit rescission for fraud or an intentional misrepresentation of a material fact.

The plan requires a questionnaire about prior medical history. It ends with a broad catch-all question asking whether there is anything else relevant to the person's health that the plan should know.

The individual inadvertently omits two visits to a psychologist six years earlier. A serious diagnosis follows, benefits are sought, and the insurer learns of the omitted visits.

The regulation's conclusion is that the plan cannot rescind the coverage. The failure to disclose was inadvertent, so it was neither fraudulent nor an intentional misrepresentation of material fact.

The exception turns on intent, not on completeness. A second example makes the other half explicit: where an employee became ineligible and the plan kept collecting premiums by mistake, the plan cannot rescind, though it may cancel prospectively subject to other law.

The six grounds for ending coverage going forward

The renewal rule starts from the opposite presumption. An insurer offering coverage in the individual, small group or large group market must renew or continue it in force at the option of the plan sponsor or the individual.

It may nonrenew or discontinue based only on one or more of six listed grounds. Nonpayment of premiums or contributions in accordance with the terms of the coverage, including any timeliness requirements.

Fraud, or an intentional misrepresentation of material fact in connection with the coverage. For group coverage, failure by the plan sponsor to comply with a material plan provision on employer contribution or group participation rules under applicable state law.

Termination of the product, where the insurer is ceasing to offer coverage in the market under the section's own procedures.

For a network plan, movement outside the service area, defined as there no longer being any enrollee who lives, resides or works in the insurer's service area or authorized territory.

And, for coverage made available only through a bona fide association, the end of the employer's membership in that association, but only where coverage terminates uniformly without regard to any health status-related factor.

What is not on that list

A closed list is most useful for what it leaves out, and this one leaves out the thing people most fear.

The cost of a person's claims is not a ground. Neither is a diagnosis, a medication, or the arrival of an expensive one.

The section reinforces that at the product level. Where an insurer discontinues a particular product, it must act uniformly without regard to the claims experience of those sponsors or individuals, or any health status-related factor.

One further sentence rules out a common assumption directly. Medicare entitlement or enrollment is not a basis to nonrenew an individual's coverage in the individual market under the same policy or contract.

There is a construction clause pointing the other way, and it belongs beside all of this. Nothing in the section requires an insurer to renew coverage for which continued eligibility would otherwise be prohibited under federal law.

So the protection is against the reasons that are not listed, rather than a guarantee that any particular product will exist next year.

When a product or a market goes away

The commonest way coverage ends is not about any individual at all, and the rule attaches notice periods to it.

Where an insurer discontinues a particular product in a market, it must give written notice at least 90 calendar days before the coverage will be discontinued. That notice goes to each affected sponsor or individual and to participants and beneficiaries covered.

It must also offer the option, on a guaranteed availability basis, to purchase other coverage it currently offers in that market. In the large group market that option may be limited to any other coverage rather than all of it.

Where an insurer leaves a market in a state entirely, the notice period is longer. Written notice must go to the state authority and to each sponsor or individual at least 180 calendar days before the discontinuation.

A consequence attaches to that choice. An insurer that discontinues all coverage in a market in a state may not issue coverage in that market and state during the five-year period beginning on the date of the last coverage not renewed.

The section also defines when an insurer has not really left, including where it or another member of its controlled group still offers the same product in that market and state.

Changing coverage instead of ending it

Between renewing and ending sits a third option, and the rule confines it to a moment.

Only at the time of coverage renewal may an insurer modify the coverage for a product offered in the large group market. The same is true in the small group and individual markets, where the modification must be consistent with state law and applied uniformly.

Modifications made uniformly and solely to comply with a federal or state requirement count as uniform, provided they are made within a reasonable time and are directly related to that requirement.

Other uniform modifications in the individual or small group markets qualify only if several conditions hold together. The same insurer or controlled group, the same product network type, and at least a majority of the same service area.

Each plan within the product must keep the same cost-sharing structure, apart from variation solely related to changes in cost and utilization or to maintaining a metal tier level.

And the product must provide the same covered benefits. The exception is for changes whose cumulative effect on the plan-adjusted index rate stays within an allowable variation of two percentage points, excluding changes required by federal or state law.

Which coverage each rule reaches

The two rules have different footprints, and the difference decides which one is worth quoting.

The rescission rule reaches a group health plan and an insurer offering group or individual coverage. It says in its own words that the 30-day notice applies whether group coverage is insured or self-insured, and whether the rescission would affect a whole group or one person within it.

It also states that its rules apply regardless of any contestability period that might otherwise apply under the contract.

The renewal rule binds an insurer. A self-funded employer plan has no insurer renewing a policy, so that section does not describe it.

Grandfathered coverage splits the two. The renewal section says it does not apply to grandfathered health plans, while the preservation regulation lists the statutory provision behind the rescission rule among those that do apply to them.

Both regulations also close with a reminder that other federal or state law may apply in connection with the same events.

What none of this settles

None of it is a promise that coverage will keep paying for a particular medication.

A plan can leave a drug off a list, apply prior authorization, or move a tier without ending anyone's coverage. That is a benefit design question, and it is handled in the guides on drug lists and on mid-year change.

The statute ties the two halves of this article together in one sentence. It says coverage may not be cancelled except with prior notice to the enrollee, and only as permitted by the guaranteed renewability provisions.

So the practical order is to establish which act happened. Was the coverage undone backwards, ended going forward, or left in place with the benefit changed?

Ask in writing for the ground being relied on and the date it takes effect. A rescission requires notice ahead of it, and a discontinuance requires a notice period measured in calendar days.

None of this is legal advice. Where the amount or the medication justifies it, someone qualified to advise on health coverage is the right next call.

Frequently asked questions

I got something wrong on a health questionnaire. Can my coverage be undone?

The bar on rescission has one exception, and it turns on intent. Coverage may be rescinded only where the person, or someone seeking coverage on their behalf, commits fraud or makes an intentional misrepresentation of material fact. The act, practice or omission has to be one the terms of the plan or coverage prohibit. The regulation's own worked example is an applicant who inadvertently omits two psychologist visits from six years earlier, in answer to a broad catch-all question. Its conclusion is that the plan cannot rescind, because an inadvertent omission is neither fraudulent nor intentional. Even where the exception applies, at least 30 days advance written notice is required first.

What is the difference between a rescission and an ordinary cancellation?

Direction in time. A rescission is defined as a cancellation or discontinuance of coverage that has retroactive effect. The regulation gives two illustrations: treating a policy as void from enrollment, and voiding benefits already paid up to a year earlier. A cancellation with only prospective effect is not a rescission at all. Neither is a retroactive cancellation attributable to a failure to timely pay required premiums or contributions. Nor is one the individual initiated without the plan influencing or pressuring the decision, or one an Exchange initiated under its own termination rule apart from one specified branch.

Can an insurer refuse to renew my coverage because my medication is expensive?

Not on that ground. An insurer offering coverage in the individual, small group or large group market must renew or continue it in force at the option of the sponsor or the individual. It may nonrenew or discontinue based only on six listed grounds. Nonpayment, and fraud or an intentional misrepresentation of material fact. A group sponsor's failure to meet contribution or participation rules, and termination of the product under the section's procedures. Movement outside the service area for a network plan where no enrollee remains in it, and the end of membership in a bona fide association. Claims cost and health status are not among them, and where a product is discontinued the insurer must act uniformly without regard to claims experience or any health status-related factor.

My insurer says it is dropping my plan. How much warning is required?

It depends on whether one product is going or the insurer is leaving the market. To discontinue a particular product, the insurer must give written notice at least 90 calendar days before the coverage will be discontinued. That notice goes to each affected sponsor or individual and to participants and beneficiaries covered. The insurer must also offer other coverage it currently sells in that market on a guaranteed availability basis. To discontinue all coverage in a market in a state, the notice period is at least 180 calendar days, and it goes to the state authority as well. The insurer may not then issue coverage in that market and state for five years.

Do these rules apply to an employer plan that pays claims from its own money?

The two rules answer differently. The rescission rule reaches a group health plan as well as an insurer. It states that its 30-day notice applies whether group coverage is insured or self-insured, and whether a rescission would affect an entire group or one individual within it. The renewal rule is written about an insurer renewing coverage, so a self-funded arrangement with no policy to renew is not what that section describes. Which regime your coverage sits in is the first thing to establish, and the guide on which rules reach your plan covers that split.

Can coverage be changed rather than ended?

Yes, and the rule confines when. Only at the time of coverage renewal may an insurer modify the coverage for a product. In the individual and small group markets a modification counts as uniform only where a list of conditions holds together. The same insurer or controlled group, the same product network type, and at least a majority of the same service area. The same cost-sharing structure apart from stated variations, and the same covered benefits apart from changes whose cumulative rate effect stays within an allowable variation of two percentage points. Changes made during a year to a drug list or a review requirement are a different subject, with their own notice duties.
