An 'extension of benefits' provision in a medical expense policy generally:

Why A is correct

Extension of benefits is a claims-protection clause found in medical expense and disability policies. If the policy is terminated, for example by the insurer's refusal to renew or by the policy's lapse, while the insured is totally disabled or confined to a hospital, benefits for that confinement or disability continue for a limited period, often up to a stated maximum such as 90 days or one year. The clause prevents an interruption of coverage at the worst possible time, when the insured cannot obtain new coverage. It is distinct from a grace period, which concerns late premium payment, and from a guaranteed renewal promise, which governs future renewals.

Why the other options are wrong

• B) The grace period is the window after the premium due date during which the insured may still pay without a lapse in coverage. It is a payment rule, not a continuation of benefits after the policy has already terminated.
• C) Adding dependents is governed by the plan's eligibility and enrollment provisions, which may require evidence of insurability and depend on the plan's schedule, not by an extension of benefits clause.
• D) Lifetime renewal is the function of a guaranteed renewable or noncancelable provision. An extension of benefits clause only continues already-incurred claims for a limited time after termination.

Memory hook

Extension of benefits = if you're laid up when the policy ends, benefits keep flowing for a while.

Why D is correct

An extension of benefits (also called continued benefits) clause protects an insured who is totally disabled when a policy terminates. The insurer continues to pay benefits for the disabling condition for a limited period after the policy ends, even though the policy is no longer in force. This prevents a gap in coverage for a loss that began while the insured was protected. The extension applies only to the condition already causing total disability, not to new conditions.

Why the other options are wrong

• A) Immediate termination would defeat the purpose of the clause, which is specifically to bridge care for an ongoing disabling condition.
• B) The extension is temporary and limited, not lifetime, and no additional premium is the norm only for that limited window.
• C) Conversion rights, not extension of benefits, would convert the coverage to an individual policy; the two provisions are distinct.

Memory hook

Extension of benefits keeps paying the disabling claim for a limited time after the policy ends. Bridge, not lifetime.
