US health insurance: what it costs and how to enroll
Updated: Author: Alina Kanametova
US health insurance per CMS: the average benchmark HealthCare.gov plan in 2025 was $497 a month at age 40 and $1,606 for a family of four, before subsidies. It is arranged in the first weeks after the move - the special enrollment window (SEP) is easy to miss. How to enroll without an SSN, where subsidies and public charge stand, and the prices chat members report. Not insurance advice.
Subsidy rules have been changing: the enhanced ACA subsidies were expiring January 1, and the 2019 public-charge rule is rescinded. Check current terms on healthcare.gov and our public-charge page.
Enrolling right after the move
The move opens a special enrollment period (SEP) on the marketplace - do not wait for open enrollment. Per healthcare.gov, lawfully present immigrants, including those on a valid nonimmigrant visa, can buy a marketplace plan. The community praises free brokers: by reports they accepted status documents before the SSN arrived and attached the number later.
Subsidies, public charge and the fears
Many avoid subsidized plans "because of public charge". The 2019 rule is rescinded, yet the fear persists in the chats; the folk formula "pay yourself, skip subsidies - definitely safe" is caution, not law. Check the current rules on our public-charge page and with a lawyer if immigration steps are ahead of you.
What US health insurance costs
CMS figures for HealthCare.gov states, 2025 (before subsidies, per month): the benchmark plan (second-lowest-cost silver) - $388 for a 21-year-old, $497 for a 40-year-old, $1,606 for a family of four; the average lowest-cost plan across enrollees - $479, after subsidies $37. For 2026 CMS projected the lowest-cost plan after subsidies at $50 a month on average for those eligible. Chat prices: the cheapest marketplace plan in Los Angeles - $290 a month for one person, a "more or less acceptable" one - $400; an ACA plan covering pregnancy and childbirth - $300-500 a month depending on the state; through an employer, families paid an extra $350-800 a month, and one member paid $1,600 a month himself for a plan an employer buys for about $700. Deductibles and copays come on top and matter as much as the premium.
Community takeaway
The chats' takeaway: insurance is a week-one task, not "once we settle". The broker is free, the SEP window is finite, and one uninsured doctor visit costs more than months of premiums.

FAQ
- Can I enroll without an SSN?
- By member reports - yes: brokers enrolled people on status documents and attached the SSN later. Confirm in your state.
- Is Medicaid or CHIP risky for a future green card?
- The most common chat fear. Public-charge rules have shifted; as of 2025 reports Medicaid (except long-term care) was not counted - but this is exactly the point to verify with a lawyer and our public-charge page before an I-485.
- Low premium or low deductible?
- Members who actually needed care in year one more often regretted minimum-premium plans: a high deductible made every visit cost hundreds. Model the full-year scenario, not just the premium.
