Short-term vs Catastrophic
Short-Term Health Insurance and Catastrophic Marketplace plan solve the same problem in different ways. Short-term limited-duration insurance is designed to cover a temporary gap — between jobs, after aging off a parent’s plan, or while waiting for other coverage to start. Premiums are low, but plans can deny coverage for pre-existing conditions, skip essential benefits like maternity and prescriptions, and impose caps. Federal rules limit how long these plans can last. Treat them as a stopgap, not a replacement for comprehensive coverage. By contrast, Catastrophic Marketplace plans are ACA-compliant major medical options available to people under 30 or with a hardship exemption. They feature low premiums and very high deductibles, covering preventive care and three primary visits before the deductible in typical designs. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.
