Health Savings Accounts (HSAs) are a new way for consumers to pay for  medical expenses. As of January 1, 2004, almost anyone with a qualified  high-deductible health plan can also have a Health Savings Account. HSAs   can save you money on your medical care now as well as provide a good  way to save for future medical expenses. HSA funds can pay for expenses  before you meet your deductible as well as helps pay for services not  covered by your health plan, COBRA coverage during periods of  unemployment,  medical expenses after retirement and long-term care expenses, to name  just a few.
Your high-deductible health plan can be one you get through your  employer  or a policy you buy on your own. Even if you get your high-deductible  health plan or even your HSA account through your employer, you own your   account. You decide how much to contribute, how much of the account to  use for medical expenses, and which medical expenses to pay from your  account. You also choose whether to pay for medical expenses from the  account or save it for future use. Even if you change jobs, your Health  Savings Account is still yours.
You can keep the account even if you move to another state, and you can  continue to keep it as you grow older. Regardless of where you get your  health insurance plan, whether on your own or through your employer,  your  Health Savings Account funds are yours.
Unlike some other types of accounts, you don't lose HSA funds at the  end of the year. Unspent balances remain in your account earning  interest  until you spend them on medical care. This will be a strong incentive  for you to spend wisely on your medical care, just like you do on other  items you purchase. You'll want to shop around for the best value for  your health care dollars.

Questions and Answers About Health Savings Accounts (HSAs)
What If I Have a Qualified High-Deductible Health Plan But My Insurer  Doesn't Offer the Health Savings Account Itself?
An HSA can be established through a qualified trustee or custodian who  is different than your high-deductible health plan insurer. A trustee  can be an insurance company or bank or any institution already approved  to administer Medical Savings Accounts (MSAs) or IRAs. Other trustees  may be approved by the Treasury Department if they follow the procedures   established.
