The IRS Medical-Care Test: Why Most Baby Monitors Don't Qualify

The IRS sets the eligibility bar through IRC Section 213(d), which defines medical care as amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease — or for the purpose of affecting a structure or function of the body. That's the legal standard. IRS Publication 502 spells out what qualifies and, just as importantly, what doesn't.

The critical exclusion: expenses that merely promote general health don't qualify. A product has to be directed at a specific disease or condition. General wellness doesn't cut it.

A standard audio/video baby monitor — the kind that lets you hear your baby cry or watch the crib on your phone — fails this test outright. Its purpose is childcare convenience and parental peace of mind. Real benefits, sure. But not medical care under the IRS definition. The IRS doesn't care that the monitor reduces your anxiety at 2 a.m. It cares whether the device diagnoses, treats, or monitors a specific medical condition.

Contrast that with monitors that measure pulse oximetry (blood oxygen saturation), breathing motion, or heart rate. These devices generate clinical data about a child's physiology. When a physician has identified a specific medical risk — apnea of infancy, for instance, or low oxygen saturation in a premature infant — monitoring those vital signs can meet the IRS standard. The device stops being a childcare gadget. It's doing something medical.

Which Baby Monitor Features Actually Make It FSA Eligible?

Not all "smart" or "health" monitors are created equal. Here's how to read the spec sheet through an IRS lens.

Features that can support FSA eligibility:

• Pulse oximetry (SpO2) monitoring
• Breathing motion detection (respiratory rate tracking, not just a movement alarm)
• Continuous heart rate monitoring
• Blood oxygen saturation alerts

These features generate measurable physiological data. When a physician has documented a medical reason for tracking them, they can satisfy the "diagnosis, treatment, or prevention of disease" standard.

Features that do NOT qualify on their own:

• Two-way audio
• Night vision camera
• Room temperature or humidity sensors
• Lullaby or white-noise playback
• Wi-Fi connectivity
• Sleep tracking that's really just movement detection with no vital-sign data

There's a nuance worth flagging: the IRS evaluates primary purpose for dual-use devices. If a monitor is fundamentally a video camera with a bundled heart rate feature that's more marketing than medicine, an FSA administrator can — and often will — deny the claim. One checkbox on a spec sheet doesn't transform a baby monitor into a medical device.

Honestly, the primary-purpose rule trips up a lot of parents who buy a premium monitor assuming the health features automatically unlock FSA eligibility. They don't. The vital-sign measurement needs to be the point of the product, not an afterthought. A monitor marketed as a "health monitor" but lacking genuine, continuous vital-sign measurement is unlikely to survive scrutiny. Check what the device actually measures, not what the product name implies.

Scenario: A Pediatrician Recommends a Breathing Monitor — What Happens Next?

Picture this: a premature infant is discharged from the NICU. The neonatologist notes a documented risk of apnea — episodes where breathing slows or stops — and recommends continuous breathing and oxygen monitoring at home. The parents buy a pulse oximetry wearable monitor.

That's a fundamentally different purchase than a healthy, full-term infant's parents buying the same device because they saw it on a parenting blog.

Same physical product. Different IRS outcome.

The difference is the documented medical condition and the physician's recommendation. This is where a Letter of Medical Necessity (LOMN) comes in. A LOMN is a written statement from a licensed healthcare provider explaining why a specific item or service is medically necessary for a particular patient. It bridges the gap between a product's features and the IRS eligibility standard. Without one, a pulse oximetry monitor is just an expensive baby gadget. With it, and with the right diagnosis backing it up, the purchase can qualify as a medical expense under IRS Publication 502.

Diagnoses that typically support a LOMN for this type of device include:

• Apnea of infancy
• Prematurity with documented cardiorespiratory concerns
• Hypoxia risk or documented low oxygen saturation episodes
• Other physician-identified conditions requiring ongoing cardiorespiratory monitoring

Without a documented condition, no letter fixes the problem. The LOMN doesn't create eligibility. The medical condition does. The LOMN documents it.

How to Get a Letter of Medical Necessity from Your Pediatrician

The process is more straightforward than most parents expect, but the details matter.

Step 1: Raise it at your next appointment. A well-child visit or a follow-up after a NICU discharge or apnea diagnosis is the right moment. Be direct: tell the provider you're seeking FSA reimbursement and need a Letter of Medical Necessity. Most pediatricians have written these before.

Step 2: Make sure the letter contains the right elements. A valid LOMN should include:

• Patient's full name and date of birth
• The specific diagnosis or clinical condition ("apnea of infancy," not "general infant safety")
• A clear explanation of how the monitoring device addresses that condition
• The specific feature being recommended (e.g., "continuous pulse oximetry monitoring" — not just a brand name)
• Physician's name, credentials, and signature
• Date of the letter

Step 3: Ask for clinical specificity. A letter that says the monitor is recommended "for infant safety" or "for parental peace of mind" will almost certainly be rejected. The provider should name the condition and explain the clinical rationale. "Continuous SpO2 monitoring is indicated due to documented apnea episodes" is useful. "Baby monitor recommended" is not.

Step 4: Keep the letter on file. You don't always submit the LOMN upfront — many FSA administrators only ask for it if they flag the expense for review. But if they ask, you need to produce it. Keep the original, and keep your itemized receipt.

This documentation requirement is part of broader IRS expense substantiation rules. Think of it the way you'd think about keeping records for any tax deduction: you're not required to hand everything over immediately, but you need to have it when asked. The same principle applies to other durable medical equipment claims; see is a humidifier FSA or HSA eligible for how this plays out with a similar category.

Common Reasons Baby Monitor FSA Claims Get Denied — and How to Avoid Them

FSA administrators deny these claims more often than you'd think. Here's where parents go wrong.

Reason 1: The merchant category code triggers an automatic denial. When you swipe your FSA debit card at a retailer, the card network checks the merchant's category code against an approved list (the Inventory Information Approval System, or IIAS). Baby gear retailers aren't medical supply stores. A baby monitor purchased at a general retailer will often auto-decline at the register — not because your claim is wrong, but because the system doesn't recognize the merchant or item type as automatically eligible. Solution: pay out of pocket and submit for reimbursement with documentation, rather than relying on the FSA card to work at checkout.

Reason 2: No LOMN when one is required. If a claim is flagged for review and you can't produce a Letter of Medical Necessity, it gets denied. Full stop.

Reason 3: No documented medical condition. A healthy, full-term infant with no diagnosed condition is the clearest denial scenario. The monitor might be excellent hardware. Doesn't matter.

Reason 4: Accessories submitted as standalone claims. Sensor socks, replacement bands, charging cables — these are almost certainly ineligible on their own. The IRS medical-care test applies to each item claimed. An accessory that serves no independent medical function doesn't qualify just because the parent device does.

Reason 5: Refurbished or secondhand monitors. The IRS doesn't explicitly bar used items from qualifying as medical expenses — the eligibility rules focus on the nature of the expense, not whether the product is new. The practical problem is substantiation. A receipt from a private seller or a marketplace listing may not satisfy your FSA administrator's documentation standards. If you go this route, get an itemized receipt that clearly identifies the product.

Prevention checklist:

• Buy from a retailer that provides itemized receipts identifying the product clearly
• Have your LOMN ready before submitting, not after denial
• Submit via reimbursement rather than FSA card swipe for anything that isn't auto-adjudicated

FSA vs. HSA Eligibility: Are the Rules the Same for Baby Monitors?

Yes — and this is one area where the rules are actually simple. Both FSA and HSA accounts use the same IRS Section 213(d) definition of medical expenses. A monitor that qualifies under one account qualifies under the other, from a pure IRS-rules standpoint.

The practical difference is in how claims are reviewed. HSA funds are owner-controlled. You decide what's a qualified expense, you reimburse yourself, and you self-certify. If you're audited, you need documentation — but no one is pre-approving your HSA withdrawal the way an FSA administrator reviews claims. FSAs are employer-sponsored benefit plans subject to stricter substantiation requirements at the point of claim.

The stakes on the HSA side are real, though. Use HSA funds for a non-qualifying expense and that distribution is subject to income tax plus a tax penalty. So the eligibility question isn't academic even when no one is looking over your shoulder.

The "HSA-eligible" labels you see on retailer product pages reflect the IRS standard. They're not a separate HSA-specific certification, and they're not a guarantee. A retailer calling something "HSA-eligible" doesn't mean your plan administrator agrees, and it doesn't mean the IRS would agree if your return were examined.

Prenatal fetal heart rate monitors follow the same rules. A Doppler used to monitor fetal heart rate under physician direction for a documented high-risk pregnancy can qualify; a consumer-grade fetal monitor purchased out of curiosity almost certainly doesn't. See is a breast pump FSA eligible for a related example of how prenatal and infant care items get evaluated.

Quick-Reference FAQ: Baby Monitor FSA Edge Cases

Q: Can I use FSA funds to repair a qualifying monitor? Apply the same medical-care test. If the monitor itself qualifies — meaning it's being used to address a documented medical condition — a repair that keeps it functional can reasonably be treated the same way. Keep your LOMN and the repair receipt. Check with your administrator before assuming.

Q: We have twins, both premature. Can I claim two monitors? Possibly, but each child's medical necessity needs to be documented separately. A LOMN that references both children by name and documents the clinical rationale for each is the right approach. Don't assume one letter covers both automatically.

Q: My FSA claim was denied. Can I appeal? Yes. FSA plans governed by ERISA are required to have a claims and appeals process. If your claim is denied, request the denial explanation in writing, gather your LOMN, itemized receipt, and any supporting physician notes, and submit a written appeal. Ask for a copy of the plan documents if you haven't seen them — they should spell out the appeal timeline and procedure.

Q: Does the monitor need FDA clearance to qualify? FDA clearance is not an IRS requirement. There is no rule in Publication 502 or Section 213(d) that conditions eligibility on FDA status. That said, FDA clearance for a medical indication strengthens the argument that a device serves a genuine medical purpose. Useful supporting evidence. Not a prerequisite.

Q: My plan year ended and I forgot to submit the claim. Is the money gone? Not necessarily. Many FSA plans include a run-out period after the plan year ends during which you can still submit expenses incurred during that year. Some plans offer a grace period extension. Check your plan documents — the rules vary and your administrator controls the specifics, not the IRS. Don't wait to find out.
