Guaranteed Issue

An insurer must accept every eligible small group regardless of its claims experience or the health of its members. — Guaranteed issue, a centerpiece of the Affordable Care Act, requires health insurers to accept every eligible applicant or small group without considering health status, medical history, or claims experience. An insurer may not decline a small group, charge it more because of member health, or exclude preexisting conditions. The rule applies across the individual and small group markets and is a key ACA-era protection. It does not freeze premiums, guarantee a fixed duration, or restrict eligibility to healthy groups; rating still varies by age, geography, and tobacco use within statutory limits.

Offer and renew coverage to all applicants regardless of health status, without medical underwriting — Guaranteed issue is the ACA requirement that health insurers in the individual and small-group markets accept every applicant who applies and renew every policyholder, regardless of health status, age-related conditions, or claims history. Insurers may not medically underwrite individual and small-group applicants to decline or price coverage on the basis of health. Premiums may still vary by limited rating factors such as age, tobacco use, family size, and geographic area, but coverage itself cannot be denied on health grounds. The prohibition on health-status rating means an applicant with a serious illness pays the same base rate as a healthy applicant of the same age in the same area, with only age, tobacco use, family size, and geography adjusting the premium.
