Insulin Pump and CGM at the Body Scanner: Your TSA Pat-Down Rights (2026)

Updated October 2026 · 8 min read

The hardest 60 seconds of holiday travel with diabetes is not the boarding call or the middle seat. It is the moment at the checkpoint when the officer waves you toward the body scanner and your brain starts negotiating with itself: is my pump supposed to go in there? Do I say something? Will I hold up the whole line? Thanksgiving-week lines are the longest of the year, the scanner is on more often than in quiet months, and that anxiety moment hits more travelers than any other week.

Here is the short version that settles it: the body scanner is optional for your diabetes devices. You can opt out, you will not be asked to take the device off, and there is a clear, written procedure for what happens instead. Everything below comes from TSA's own published screening rules, not traveler lore.

The three sentences that solve the checkpoint. Say these, in this order, and the procedure takes over: 1. "I wear an insulin pump (and a continuous glucose monitor, a CGM)." 2. "I would like a pat-down instead of the body scanner." 3. "Please do not remove the device or put it on the X-ray belt." That is the whole script. Everything else on this page is what those sentences unlock.

General guidance only, not medical advice. Your care team owns the medical plan; this page owns the checkpoint plan. Airport rules change, so confirm the current process before you travel.

Track 1: you walk through the metal detector

The walk-through metal detector (WTMD, the arch you walk through) is the default first machine. Declare the device before you step in, the way the first sentence says. Then there are two outcomes.

No alarm. If the detector does not alarm, attached insulin pumps and CGMs still get one extra step in standard lanes: the officer directs you to pat down the medical device yourself, over your clothing, and then tests your hands for traces of explosives (ETD, explosive trace detection, the swab test). It takes under a minute, in the open lane, and it is the same routine for tubed pumps, tubeless pods, and CGMs.

Alarm. Some pump clips and metal hardware can set the arch off. If it alarms, the same routine follows: you pat down the device yourself, the officer tests your hands, and may also run a hand-held metal detector over the device. None of this requires taking the device off.

Track 2: you opt out of the body scanner

The body scanner (AIT, advanced imaging technology, the booth where you raise your arms) is the machine that flags worn devices and starts the stressful version of this conversation. TSA's rule is written down: if you choose not to be screened by the AIT, the officer will conduct a pat-down instead. You do not need a reason, a doctor's note, or anyone's permission.

What the pat-down looks like: the officer explains it first, uses the back of the hands for sensitive areas, and it takes a few minutes in the lane. Two rights worth knowing:

Private screening on request. At any point you can ask for a private screening room, and you may have a witness of your choice present. Ask before the procedure starts so the officer can arrange it without stopping the lane.
The device still stays on. Opting out does not mean the device comes off. The attached-device rules do not change just because you chose the pat-down track.

What TSA cannot do

This is the part that ends the anxiety, because each of these is a hard rule, not a favor the officer is doing you:

They cannot make you remove an attached device. TSA's guidance: you will not be required to remove medical devices attached to your body. If anyone suggests disconnecting the pump and putting it on the belt, that contradicts the published rule. Decline politely and ask for a supervisor if needed.
They cannot refuse the alternative. If you decline the body scanner, the pat-down happens. If you decline X-ray screening for a device, alternative screening is conducted. The option is yours to take.
They cannot X-ray a disconnected device without your okay. Devices you choose to disconnect (a tubed pump you take off yourself, a controller) may go through X-ray, but only as the default. Tell the officer you do not want a device screened by X-ray and the alternative procedure runs instead.
Supplies travel with insulin. The broader rule from the general TSA rules guide: insulin pumps and supplies must be accompanied by insulin, and medically necessary liquids get the 3-1-1 exemption when declared. The pat-down conversation goes easier when the supplies are already in the bin, declared.

TSA PreCheck: what changes with a device

PreCheck is genuinely better for device wearers, and the rule is specific: in PreCheck lanes, additional screening of your insulin pump or CGM is only required if the device alarms in the metal detector or the body scanner. No alarm means the lane moves like it does for everyone else. If it does alarm, the officer directs you to pat down the device and tests your hands, same as standard lanes. Keep PreCheck if you have it, but it does not replace knowing the opt-out script.

Which devices can actually go through the scanner

The rights above are yours regardless of the device. Whether your device can tolerate the scanner is a separate question, and the answer varies by manufacturer. One data point: Dexcom says the G7 sensor can go through walk-through metal detectors and AIT body scanners, with a pat-down or hand-wanding as the alternative, while the G6 must not go through AIT scanners. For everything else, check your maker's current guidance before you fly.

The full device-by-device comparison lives in X-Ray vs. Body Scanner vs. Metal Detector: What's Safe for Pumps and CGMs, and Omnipod 5 wearers have the dedicated Omnipod 5 TSA guide. The practical takeaway for the checkpoint line: when in doubt about your maker's stance, the pat-down track is always available, so there is never a reason to wear a device through a scanner you are unsure about.

The holiday-season logistics around the checkpoint

The rights are the same year round. Holiday travel just makes the margins thinner: longer lines, more scanners running, more chances for a rushed conversation. Three things buy back the margin:

Call TSA Cares 72 hours ahead. (855) 787-2227. A Passenger Support Specialist (PSS), an officer trained for disability and medical-condition screening, can meet you at the checkpoint and walk the lane with you. At bigger airports you can also ask for a PSS on the spot.
Arrive with the buffer. The pat-down adds minutes, not an hour, but a packed Thanksgiving-week checkpoint punishes tight connections. Give the lane 20 extra minutes.
Keep lows covered after the checkpoint. Sugar packets in the pocket through security and at the seat: 1 packet at 60 to 70, 2 below 60. Pack 20% more supplies than the trip math says, and split them so one lost bag is never all of your supplies.

Outside the US, a different rulebook runs the checkpoint, and the US script does not transfer. Airport Security with Diabetes Abroad covers the UK card rules, EU habits, and what to say when the officer does not speak English.

The checkpoint checklist

Here is the full routine, in this order:

Before the belt, tell the officer where the pump or CGM is on your body.
Say the opt-out line if you want it: "I would like a pat-down instead of the body scanner."
Walk through the metal detector if directed. Self-pat-down the device over your clothing when asked, and let the officer swab your hands.
If you opt out of the scanner, the officer conducts the pat-down. Ask for private screening and a witness any time before it starts.
Never remove the device for screening. If asked, decline and request a supervisor.
Keep disconnected devices off the X-ray belt unless you choose otherwise.
After the checkpoint, check that devices are secure, then keep sugar packets at your seat: 1 at 60 to 70, 2 below 60.
Pack 20% more supplies than the trip math says. Allow extra time at packed holiday-week checkpoints.

Frequently Asked Questions

Q: Can I refuse the TSA body scanner with an insulin pump or CGM?

A: Yes. TSA's own guidance says that if you choose not to be screened by the AIT body scanner, the officer will conduct a pat-down instead. For a device attached to your body, the usual path is a self pat-down of the device plus a test of your hands for traces of explosives. You do not need a reason, a note, or anyone's permission.

Q: Can TSA make me take off my insulin pump or CGM at security?

A: No. TSA states plainly: you will not be required to remove medical devices attached to your body. If a device is disconnected, it may be screened by X-ray, but you can decline the X-ray for a device and alternative screening will be conducted.

Q: What is the self-pat-down of an insulin pump at TSA?

A: In standard lanes, TSA directs you to pat down the pump or glucose monitor over your clothing yourself, then tests your hands for traces of explosives. It takes under a minute, it happens in the open lane, and it is the same routine for pumps, CGMs, and tubed or tubeless devices.

Q: Does TSA PreCheck change the screening for a pump or CGM?

A: Mostly for the better. In PreCheck lanes, additional screening of your insulin pump or CGM is only required if the device alarms in the walk-through metal detector or the body scanner. If it does alarm, the officer directs you to pat down the device and tests your hands for traces of explosives, same as in standard lanes.
