Federal Guidance on Short-Term Limited-Duration Insurance and Mental Health Parity
The Centers for Medicare & Medicaid Services (CMS) issued final rules in April 2024 aimed at restricting the duration and marketing of short-term limited-duration insurance (STLDI) plans. According to the U.S. Department of Health and Human Services, these regulations limit STLDI policy terms to three months, with a maximum of four months total, to prevent these products from being marketed as long-term alternatives to Affordable Care Act (ACA) compliant coverage.
How the 2024 Rule Changes Insurance Access
The final rule reverses a 2018 Trump-era regulation that had extended the maximum duration of short-term plans to 364 days with the option to renew for up to three years. Under the current CMS framework, short-term plans must now include clear disclosures stating that the policies do not meet the definition of minimum essential coverage under the ACA. This means these plans are not required to cover pre-existing conditions, including mental health disorders or substance use conditions, and are not subject to federal parity requirements.
Why Federal Regulators Targeted Short-Term Plans
Regulators argue that short-term plans have historically created a “dual market” that destabilizes the individual insurance pool. By allowing healthier individuals to migrate to cheaper, limited-benefit plans, the risk pool for ACA-compliant plans often skews toward those with higher health needs, driving up premiums for comprehensive coverage. According to the Office of the Assistant Secretary for Planning and Evaluation (ASPE), STLDI plans often exclude coverage for essential services such as maternity care, prescription drugs, and mental health treatment, leaving consumers financially vulnerable during medical emergencies.
Comparison of Coverage Standards
The following table outlines the primary differences between ACA-compliant plans and short-term limited-duration insurance as of 2024:
| Feature | ACA-Compliant Plans | Short-Term (STLDI) Plans |
|---|---|---|
| Pre-existing Conditions | Must be covered | Often excluded |
| Mental Health/Substance Use | Essential health benefit | Frequently excluded |
| Maximum Duration | Indefinite | 3 months (4 months total) |
| Federal Parity Laws | Applicable | Not applicable |
What Happens to Current Policyholders
The rule includes a transition period for plans issued or sold before September 1, 2024. Consumers currently enrolled in 364-day plans are generally permitted to keep their coverage until the end of their current term. However, insurers are prohibited from offering renewals that extend beyond the new four-month cumulative limit. State insurance commissioners maintain the authority to impose stricter regulations than the federal baseline, with several states, including California and New York, already having banned or significantly restricted the sale of these products prior to the federal update.
Frequently Asked Questions
- Do these rules apply to all health insurance? No, these regulations specifically target short-term limited-duration insurance and fixed-indemnity excepted benefits. They do not affect employer-sponsored plans or ACA marketplace exchange plans.
- Can I still buy a short-term plan? Yes, but the plans will have shorter effective periods and must provide clearer warnings about what they do not cover.
- Does this affect mental health parity? Yes. Because short-term plans are exempt from the Mental Health Parity and Addiction Equity Act (MHPAEA), they are not required to provide the same level of coverage for mental health services as they do for medical and surgical benefits.
The Biden-Harris administration maintains that these changes are necessary to protect consumers from “junk insurance” that fails to provide adequate protection. Conversely, some industry groups argue that these restrictions limit consumer choice and affordability for those who do not qualify for, or cannot afford, premium subsidies available on the federal marketplace.
