Are Water Flossers FSA Eligible?

Flexible Spending Accounts (FSAs) are a financial tool allowing individuals to set aside pre-tax dollars from their paycheck for eligible medical expenses. This reduces taxable income, leading to tax savings. FSAs help save money on out-of-pocket health costs not covered by insurance. Understanding eligible expenses is essential to maximize FSA benefits.

Eligibility of Water Flossers

Water flossers are not universally considered eligible for reimbursement through Flexible Spending Accounts. These devices are classified as tools for everyday dental hygiene and health maintenance, similar to toothbrushes or regular dental floss. They do not automatically meet the Internal Revenue Service (IRS) criteria for a qualified medical expense.

However, a water flosser can become eligible if a healthcare provider determines it is medically necessary to treat or alleviate a specific medical condition. This applies to conditions such as gum disease (gingivitis), periodontitis, or oral health complications related to diabetes. Eligibility can also extend to post-surgical dental care, where the device is recommended to maintain cleanliness.

To establish this medical necessity, a Letter of Medical Necessity (LMN) from a qualified healthcare provider, such as a dentist or physician, is required. This document serves as official confirmation that the water flosser is not for general health purposes but rather for the diagnosis, treatment, or prevention of a diagnosed medical condition. Without this specific documentation, reimbursement for a water flosser is not permitted under FSA guidelines.

Understanding FSA Eligibility

The IRS broadly defines medical expenses as costs paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for affecting any structure or function of the body. This definition helps differentiate eligible expenses from those primarily for general health or cosmetic purposes.

Common categories of eligible expenses include doctor visits, prescription medications, dental treatments like cleanings and fillings, and vision care such as eyeglasses or contact lenses. Over-the-counter medications and certain medical supplies are often eligible. However, items that are merely beneficial to general health, like vitamins or health club memberships, are not eligible unless prescribed for a medical condition.

When an item like a water flosser requires a Letter of Medical Necessity (LMN), this document must contain specific details to be valid. The LMN typically needs to include:
The patient’s name.
A clear diagnosis of the medical condition.
A detailed explanation of why the product or service is necessary for treatment or mitigation.
The duration for which the treatment is expected to be needed.
The date and signature of the attending healthcare provider, confirming their professional relationship and providing contact information.

Using Your FSA Funds

Once an item’s eligibility has been established, using FSA funds is straightforward. Many FSA plans provide a debit card for direct payment at the point of purchase. This card functions like a regular debit card but is linked to your FSA balance and can only be used for eligible expenses.

For purchases made without the FSA debit card, or for services, individuals submit a claim for reimbursement. This process involves providing itemized receipts that clearly show the date of service or purchase, the vendor, the specific item or service acquired, and the amount paid. Credit card receipts or balance-forward statements are insufficient as they lack the necessary detail.

After submitting the claim and supporting documentation, the FSA administrator reviews the submission to ensure it complies with IRS regulations and plan rules. Upon approval, the reimbursement amount is issued to the participant, either through direct deposit or a check. Maintaining thorough records of all FSA-related expenses and reimbursements is important for tax purposes and audits.
