HSA Eligible Baby Items: What's Covered and How to Unlock More for Mom & Baby

A healthy family is expensive before you ever set foot in a pediatrician's office. In 2025, the average cost of raising a child under five reached $27,743 a year, and in the priciest states it now tops $44,000. That's on top of prenatal care and the cost of pregnancy itself, and it’s why so many parents feel the squeeze in the very first months.

Thankfully, there are ways to lower the out of pocket costs of raising a healthy child, and one area many families overlook is their Health Savings Account (HSA) or Flexible Spending Account (FSA). These tax advantaged accounts can cover far more of your family's health needs than the obvious thermometer and Tylenol. Breast pumps, prenatal vitamins, smart sleep tech, humidifiers, and more may be eligible for HSA/FSA spending, saving customers an average of 30% versus paying out of pocket.

The catch is that eligibility isn't a single fixed list. Some items are always eligible, while many more become eligible once a healthcare provider documents the medical need in a Letter of Medical Necessity (LMN). Understanding that distinction is how you turn your HSA/FSA into a real tool for your whole family, from bump to baby to growing kid. Let's break it down.

The IRS standard, in plain English: a qualified medical expense must be primarily to treat, prevent, diagnose, or mitigate a medical condition, not for general health or wellness. That single rule explains almost every "yes," "no," and "it depends" you'll run into when trying to spend your HSA funds on baby gear.

In practice, baby and family health products fall into two buckets:

1. Always eligible. Items that are inherently medical, including breast pumps, nasal aspirators, thermometers, infant pain relievers. These products typically do not require additional documentation meaning you can just pay with your HSA/FSA card and you’re done.

2. Potentially eligible with a Letter of Medical Necessity (LMN). This is the bucket most parents don't know about. Many high-quality baby health products are "dual-use,” meaning they serve a general purpose and support a genuine medical need for some babies and mothers. When a licensed provider documents that connection in an LMN, those products may be HSA/FSA eligible.

A letter of medical necessity is a formal document from a licensed healthcare provider explaining why a particular product, treatment, or service is necessary to cure, treat, mitigate, or prevent the patient's health [or medical] condition.

Traditionally, getting one meant booking a doctor's visit and chasing paperwork. But thanks to platforms like Truemed*, qualified customers can acquire a letter of medical necessity in the checkout flow for the desired health tool, no in person visit required.

Remember, the rules for spending your HSA/FSA on yourself are different than spending those funds on someone else. We’re dive deeper into the rules of spending pre-tax HSA/FSA funds on a dependent below.

Here’s how it works with Truemed:

• First, you can check whether a product or service is normally considered a qualifying medical expense or whether you might need an LMN.
• Complete a health intake survey that will be reviewed by an independent licensed clinician.
• Buy the item; either pay directly with your HSA/FSA card at checkout, or pay with a regular credit/debit card and seek HSA/FSA reimbursement afterward.
• The independent licensed clinician will review your medical history, and if you qualify, will issue an LMN. Truemed itself does not make eligibility determinations.
• Truemed also offers support in the event you get a denial of reimbursement and need to provide substantiation documentation.

Yes, generally you can use your HSA or FSA funds on your baby’s health and medical expenses, but eligibility depends on your baby being a "tax dependent," which is a narrower category than you might expect. Your HSA or FSA can be used tax free on qualified medical expenses for yourself, your spouse, and anyone who qualifies as your tax dependent under IRC Section 152.

A newborn qualifies as a tax dependent from birth, as long as they live with you and you provide more than half their support. You don't need to have added them to your insurance plan yet, and you don't need a Social Security number in hand to start using HSA/FSA funds on their care.

Where this gets confusing is with older kids. Under the ACA's dependent coverage rule, a child can stay on a parent's health insurance until age 26, even if the parent doesn't claim them as a tax dependent. But that's a different rule from the tax dependent test that governs HSA/FSA reimbursement. To count as a tax dependent, a child generally needs to meet the IRS's qualifying child test which means they are under 19, or under 24 if a full-time student, and not providing more than half of their own support. Parents sometimes assume “on my insurance” means “covered by my HSA,” but it doesn’t always work that way.

The bottom line for new parents is that your baby counts from day one, and many medically necessary baby items are HSA/FSA eligible, helping save on those expensive newborn costs in the first year of life.

Short answer: standard baby formula is generally not HSA/FSA eligible as a routine grocery. However, baby formula may be eligible for qualified customers when linked to a medical need and supported by appropriate documentation.

The IRS treats ordinary formula the way it treats regular food: a normal cost of living, not a medical expense. So a tub of standard formula off the shelf typically can't be reimbursed on its own.

Here’s where this changes:

• Medically necessary or specialized formula. When a child has a diagnosed condition, like a metabolic disorder, severe allergy, malabsorption, or similar, and a provider prescribes a specialized formula, the incremental cost (the difference between the special formula and ordinary formula) can qualify with proper documentation.
• With a Letter of Medical Necessity. If a provider documents that a specific formula supports your child's specific health needs, an LMN may support reimbursement of qualifying costs.
