Can You Use EOB for HSA Reimbursement?

Health Savings Accounts (HSAs) offer a tax-advantaged way for individuals to save and pay for qualified medical expenses. These accounts allow for tax-deductible contributions, tax-free growth, and tax-free withdrawals when used for eligible healthcare costs. Understanding the documentation required for out-of-pocket reimbursements is important for account holders. Explanation of Benefits (EOBs) are common documents received after medical services, and their role in HSA reimbursement often raises questions.

Understanding Explanation of Benefits (EOB)

An Explanation of Benefits (EOB) is a statement sent by your health insurance company after you receive medical care. Its primary purpose is to detail how your insurance plan processed a claim for services. An EOB is not a bill from your healthcare provider; rather, it is a summary of the financial transaction between your insurance company and the provider.

This document typically includes information including the date of service, the healthcare provider’s name, the type of service rendered, and the total charges. It also specifies the amount your insurance plan paid, any discounts applied, and the portion you are responsible for, including deductibles, copayments, or coinsurance. The EOB helps you understand how your benefits were applied to a specific medical event.

Qualified Medical Expenses for HSA

For an expense to be reimbursed from a Health Savings Account, it must meet the Internal Revenue Service (IRS) definition of a “qualified medical expense.” These are generally costs incurred for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for affecting any structure or function of the body. Examples include fees for doctors’ visits, prescription medications, dental care, and vision services, as well as deductibles and copayments.

Certain expenses, such as over-the-counter medications and menstrual care products, became qualified medical expenses without a prescription. Expenses must be medically necessary to qualify. If HSA funds are used for non-qualified expenses, the distribution becomes taxable income and may incur an additional 20% tax penalty, unless the account holder is age 65 or older.

Required Documentation for HSA Reimbursement

While Explanation of Benefits (EOBs) are helpful for tracking insurance payments and amounts you owe, they are generally not sufficient for IRS substantiation of HSA distributions. An EOB details how your insurance processed a claim and the amount you are responsible for, but it does not typically serve as proof that you have actually paid that amount to the healthcare provider. For audit purposes, the IRS requires documentation proving the distributions were exclusively for qualified medical expenses and these expenses were not reimbursed from another source or taken as an itemized deduction.

The documentation typically required includes an itemized receipt or invoice directly from the healthcare provider. This document should clearly show the date of service, a detailed description of the service or product, the amount charged, and proof of payment by the patient. Proof of payment can include a credit card receipt, a canceled check, or a statement from the provider showing a zero balance or payment received. It is important to retain these original documents for at least three years from the tax filing date, or longer if the HSA remains open, in case of an IRS audit.

Managing Your HSA Reimbursements

Managing your Health Savings Account reimbursements requires diligent record-keeping. While your HSA administrator may not require receipts for every withdrawal, you are responsible for substantiating that all distributions are for qualified medical expenses in an IRS audit. Create a systematic approach for organizing your documentation, such as digital folders categorized by year and expense type, or using online tools offered by some HSA providers.

You have the flexibility to pay for qualified medical expenses out-of-pocket and reimburse yourself from your HSA at a later date, even years later, as long as the expense was incurred after your HSA was established. This strategy allows your HSA funds to grow tax-free over a longer period. When ready to reimburse, you can initiate a withdrawal through your HSA provider’s online portal, by requesting a check, or by direct transfer to a linked bank account. Maintaining comprehensive records, including both EOBs and proof of payment, helps ensure compliance and simplifies future financial management.
