Medical alerts with fall detection: what they can and can't do
By ParentNextStep Editors · Updated October 14, 2026
Fall detection can call for help when your parent can't press the button. It doesn't catch every fall, so here's how to judge whether it's worth adding.
Why it matters
About 1 in 4 adults 65 and older report a fall each year, and falls are the leading cause of injury for that age group, according to the CDC. Getting up can be the hard part: in one study of people 72 and older, nearly half of those who fell without being hurt couldn't get up on their own after at least one fall. In a study of people over 90, lying on the floor for a long time was strongly linked to serious injury, hospital stays and moves into long-term care, and most of them didn't use the alarm they had.
How fall detection works
A medical alert with fall detection has motion sensors in the pendant, wristband or watch. When they sense the sudden movement and impact of a fall, the device calls the monitoring center, even if your parent can't press the button. Companies usually charge extra for it: $5 to $10 a month for the plans we compare.
What it can't do
- It misses some falls. In a study of 13 fall detection methods tested on 29 real falls, they caught 57% on average and 83% at best, far fewer than in lab tests. Slow slides to the floor are the hardest to detect. No government standard checks how well these devices work, and makers say they can't catch every fall.
- False alarms happen. Sudden movements that look like a fall can set it off; your parent just tells the operator they're fine.
- It only works if it's worn. The National Institute on Aging says these systems must be worn and kept charged. In one small study, most falls happened while the device wasn't being worn, half of them while it was charging. Bathrooms are a common place to fall, so pick a device that can be worn in the shower.
- The button still matters. Teach your parent to press it after any fall, even if the device should call on its own.
Landline or cellular
An in-home system works through a base unit that plugs into a landline or uses a cellular signal; mobile devices and smartwatches use cellular service and work wherever there's coverage. If your parent's phone line has moved from copper wires to an internet or fiber service, check with the company that the alert will work on it, and that it has backup power in an outage. Older devices that used 3G cellular networks no longer work.
Who pays
Original Medicare doesn't pay for medical alert systems. Some Medicare Advantage plans offer one as an extra benefit, and some state Medicaid programs cover them for people who qualify, so ask before you buy.
Is it worth it?
If your parent has fallen, worries about falling, or lives alone, fall detection is worth considering as a backup to the button, as long as they'll wear the device. Our medical alert comparison adds the fall detection fee to every first-year price, and drops plans that don't offer it. If daily tasks are getting harder too, a few hours of help at home covers what a device can't.
