'HSA' originates from the United States, specifically the term 'Health Savings Account', where 'health' refers to medical well-being, 'savings' refers to money set aside, and 'account' refers to a financial arrangement.

'Health Savings Account' was introduced in the early 2000s as a part of the Medicare Prescription Drug, Improvement, and Modernization Act.

Initially, it was introduced as a way to save money for medical expenses, and this meaning has remained consistent.
