Direct answer: A medical alert system is a wearable button that connects a person to help when they cannot reach a phone. Original Medicare generally does not pay for one. CMS treats it as a communication device, not medical equipment. Some Medicare Advantage plans and state Medicaid programs do help, but most families pay out of pocket.
When you shop for a medical alert device, the biggest choice is who answers the call. A trained operator costs a monthly fee. A list of family phone numbers is free, but at 3 a.m. it may ring through to voicemail.
The worry behind the search is real. The CDC reports that falls are the leading cause of injury for adults 65 and older. About 1 in 4 older adults report a fall each year. That is more than 14 million people.
If you are reading this at the kitchen table, worried about a parent, take a breath. You can sort this out in an afternoon, and you do not need to buy anything today.
A device does not stop a fall. Its job is to shorten the time a person lies on the floor, hurt and alone. That only works if the device is on their body and someone picks up.
What is a medical alert system, and what kinds are there?
The industry name is PERS. That stands for personal emergency response system. Every version is a chain with four links:
- The trigger. This is a button press, a voice command, or a fall sensor.
- The connection. This is a home base station or a mobile unit with its own cell service.
- Who answers. This is a monitoring center staffed around the clock, or your own list of contacts.
- What happens next. The responder talks through the speaker, then calls family or 911.
When a salesperson pitches a feature, ask which link it makes stronger. A louder speaker helps. A faster answer at night helps. Most other extras do not.

| Type | Where it works | Who usually answers | Main weak spot |
|---|---|---|---|
| In-home base with pendant | Inside the home, within range of the base | Monitoring center | No help once they leave the property |
| Mobile GPS pendant | Wherever cell service reaches | Monitoring center | Needs charging every few days |
| Fall detection add-on | Built into a pendant, mobile unit or watch | Depends on the device | Misses some falls, goes off on some non-falls |
| Smartwatch with emergency calling | Near a paired phone, or with a watch cell plan | Often 911 or contacts, not a center | Daily charging and small buttons |
Why does Medicare say no?
CMS keeps a reference list for medical equipment in National Coverage Determination 280.1. Telephone alert systems sit on the deny side of that list. The reason is simple. They are for emergency calls, and they do not diagnose or treat anything.
A doctor’s note does not change that. Medigap policies follow Original Medicare’s rules, so they do not add this coverage either.
Medicare Advantage works differently. Some plans add a personal emergency response benefit as an extra. It is plan by plan, and it can change each year. It may also tie you to one vendor. Read the plan’s Evidence of Coverage, not the TV ad.
In my 18 years in insurance marketing, I have seen ads blur these two on purpose. An ad that says Medicare plans almost always means one private Advantage plan. It does not mean Medicare itself pays.
Medicaid can help too. Many states cover these systems through home and community-based services for people who qualify. Rules and waitlists differ by state.
What can a fall cost under Medicare in 2026?
A medical alert device is not covered. The hospital stay after a fall is. Here is what that can look like using 2026 figures from Medicare.gov.
Say a parent on Original Medicare falls and is admitted to the hospital. After a qualifying stay, they spend 30 days in a skilled nursing facility for rehab. They have no Medigap plan.
Swipe sideways to see every column.
| Cost item | 2026 amount |
|---|---|
| Part A hospital deductible | $1,736 per benefit period |
| Skilled nursing, days 1 to 20 | $0 |
| Skilled nursing, days 21 to 30 (10 days at $217) | $2,170 |
| Part B deductible | $283 |
| Total before Part B coinsurance | $4,189 |
On top of that, Part B coinsurance is 20% of approved doctor bills. The Part B premium of $202.90 a month keeps running too. If rehab ran all the way to day 100, days 21 to 100 alone would cost $17,360. A Medigap plan may pick up some of this.
Medicare does cover some fall prevention. The yearly Wellness visit includes a review of safety and how well a person gets around. Ask the doctor about fall risk by name. The CDC built its STEADI program to help doctors screen for it.
Where medical alert systems fail
Most failures are habits, not hardware. Here are the weak spots to plan around.
Fall detection misses things. A slow slide out of a chair may not register. A fall onto a soft rug can slip past it. A pendant on the nightstand catches nothing. On the flip side, sitting down hard or dropping the pendant can set it off.
Mobile units need charging. A GPS pendant sitting dead by the bed is worth nothing. Tie charging to a daily habit, like morning coffee.
Signal can drop. Ask which cell network the device uses. Then check coverage in the basement and the back bedroom. When carriers shut down 3G in 2022, the FCC warned that some medical devices could lose service. Ask what the company does when a network retires.
Power goes out. Home base stations have a backup battery, but only for a while. The FCC also notes that internet phone service may fail in an outage without backup power.
It comes off in the shower. Ask if the device is rated for water. If it is, it never has to come off to wash.
Do you really need fall detection and a monthly fee?
The usual advice is to buy every feature. I push back on that. The right setup depends on the person.
When fall detection earns its cost
Fall detection makes sense for someone who lives alone and might pass out. Dizzy spells or memory trouble are good reasons too. If they could be knocked out or confused, they may not press a button. It often costs extra each month, so ask.
When a plain button is enough
Some people are sharp and steady and always wear the pendant. For them, a plain button may do the job. Keep pressing the button as the first habit either way. Fall detection is a backup.
When no monthly fee makes sense
Self-monitored systems dial your contact list instead of a center. That can work for a couple who live together. It also fits someone with a neighbor who is home all day and has agreed to be first call. It is a weak fit for someone who lives alone with family hours away. Test it at 2 a.m. before you count on it.
When a smartwatch fits
A watch works well for someone who already wears one and charges it every night. It works poorly with arthritis or poor eyesight. Many watches call 911 directly, so the wearer must be able to speak and explain where they are.
Where the money goes
Medical alert is a subscription business. The profit is in the monthly fee, paid month after month for years. That is why you see so many free equipment offers. The company gets back the cost of the device over the contract.
I have spent my career building lead funnels for products like this. TV and online ads drive calls into sales centers. Companies and their partners often pay for each lead or each sale. So the person on the phone is paid to close a contract. Finding the right fit for your parent is not their job.
Watch three spots in the contract. One is how long the price is locked. Another is auto-renewal. The last is the fee for equipment you do not send back.
Then there is the outright scam. The FTC has sued operations that used robocalls to pitch free medical alert devices to older adults. Callers claimed a relative had already paid. Then they charged the person’s card or bank account.

Six moves before you sign
- Check for help first. Call the Medicare Advantage plan and ask about a personal emergency response benefit. Ask the state Medicaid agency too. Your local Area Agency on Aging, found through the Eldercare Locator, may know of loan programs.
- Decide who answers. Pick a monitoring center or a contact list based on who lives nearby and who is awake at night.
- Get a written 12-month total. It should list equipment, activation, the monthly fee, any fall detection fee, and spouse coverage. Ask about a key lockbox, shipping, and return fees.
- Ask about the monitoring center. Is it staffed all day, every day? How fast did they answer last month? Can they speak your parent’s language?
- Test the signal and range. Try it from the far bedroom, the basement stairs and the mailbox.
- Run a 30-day trial. Wear it for a full week, including in bed. Place a test call. Confirm the center has the right address. Check the first bill against the quote. Then ask your parent, honestly, if they wear it.
What not to do
- Do not give a card or bank number to anyone calling about a free device. Hang up on recorded sales calls.
- Do not press a number to opt out. Report the call at ReportFraud.ftc.gov and add the number to the Do Not Call Registry.
- Do not sign a long contract with no refund window.
Frequently asked questions
Does Medicare pay for a medical alert system?
Original Medicare generally does not. CMS lists telephone alert systems as emergency communication devices, not medical equipment, so a doctor’s note will not change the answer. Medigap follows the same rule. Some Medicare Advantage plans include a benefit as an extra, and some state Medicaid programs cover these systems for people who qualify. Check the plan’s Evidence of Coverage for details.
Is a smartwatch as good as a medical alert pendant?
It can be for someone who already wears a watch and charges it every night. Many watches call 911 or a contact list directly instead of a trained operator. That means the wearer has to explain what happened and where they are. For someone who forgets to charge things, a pendant with a long battery life is usually the safer pick.
Are no monthly fee medical alert systems worth it?
They save money, but they swap a trained operator for your own contact list. If your contacts are asleep or driving, the call rolls to the next name or to voicemail. They fit best when someone reliable lives in the home or right next door. Test one late at night before you trust it.
How accurate is automatic fall detection?
No sensor catches every fall. Slow slides and soft landings can slip past it, and sitting down hard can set it off. Treat it as a backup to pressing the button. Ask the company how false alarms are handled, whether they send help if no one answers, and whether the sensitivity can be adjusted.
Will a medical alert system work during a power outage?
Mobile units run on their own batteries, so they keep working as long as they are charged. Home base stations usually have a backup battery that lasts a limited time. If the base uses an internet phone line, that line may need its own backup power. Ask the company how many hours the backup lasts.
Your next step
Start with one phone call to the Medicare Advantage plan or your state Medicaid office to see if help is available. Then get two written 12-month quotes and compare them line by line. If the bigger question is whether home is still the right place, read our guide on when to move to assisted living.
