Fiber: FSA Eligibility

Fiber, when prescribed by a medical doctor to treat or alleviate a specific medical condition, is eligible for reimbursement with a flexible spending account (FSA), health savings account (HSA), or a health reimbursement arrangement (HRA). Fiber is not eligible with a dependent care flexible spending account (DCFSA) or a limited care flexible spending account (LCFSA).

What is Fiber?

Fiber is also called dietary fiber or roughage, and it's the digestible portion of food that is derived from plants. Fiber is sold in pill and powder form for efficient ingestion as a dietary supplement, and fiber may be prescribed to treat or prevent various illnesses or conditions. Fiber acts by changing the nature of the contents and absorption within the digestive system, specifically the gastrointestinal tract. Fiber is primarily prescribed to aid with constipation as well as loose stools. Fiber acts to bulk up the body's production of solid waste, improve (shorten) transit time, and ease passage (Medical News Today).

Fiber is normally prescribed as a fiber supplement in the form of chewable tablets, pills, or water-soluble powder that is intended to be consumed as a beverage. Fiber is available Over-the-Counter (OTC) but must be prescribed by a medical doctor to be eligible for reimbursement with a consumer-directed healthcare account. Fiber prescription directions should be carefully followed to avoid side effects from consuming too much fiber. Fiber can also interfere with the absorption of some nutrients and medications.

In addition to helping with problems producing and expelling solid waste, fiber may be prescribed in support of healthy eating habits. Fiber can help with achieving proper satiation while consuming meals due to its role in the digestive system and its effects on absorption of nutrients (WebMD).
