The Full Form of HSA is Health Savings Account.

A Health Savings Account (HSA) is like a personal savings account, but it can only be used for qualified healthcare expenses. To be eligible, you must be enrolled in a High-Deductible Health Plan (HDHP). Health Savings Accounts also have some important tax advantages.

While you can use the funds in an HSA at any time to pay for qualified medical expenses, you may contribute to an HSA only if you have a High Deductible Health Plan (HDHP) — generally a health plan (including a Marketplace plan) that only covers preventive services before the deductible. For plan year 2019, the minimum deductible is $1,350 for an individual and $2,700 for a family. For plan year 2020, the minimum deductible for an HDHP is $1,400 for an individual and $2,800 for a family. When you view plans in the Marketplace, you can see if they’re “HSA-eligible.”
