Traveling With Medical Devices: What You Need to Know at Airport Security

Medical devices have their own TSA rules, separate from liquids and electronics

The TSA does not require you to remove most medical devices during screening — insulin pumps, continuous glucose monitors, pacemakers, and similar equipment can stay on your body or in your carry-on. However, you do need to tell the officer at the checkpoint that you have a medical device, and some devices will trigger additional screening steps. The rules depend on what the device is, whether it contains batteries, and whether it can pass through an X-ray machine safely.

If you wear or carry a medical device, your best move is to inform the TSA officer before you reach the metal detector or body scanner. Hand them your device documentation — most manufacturers provide wallet cards or letters — so the officer knows what they are looking at. This prevents confusion and usually speeds up the process.

Devices that contain metal or are sensitive to radiation may require a pat-down instead of a scanner pass-through. Some devices, like certain pacemakers or insulin pumps, should not go through metal detectors at all. The TSA officer will know this, but telling them upfront means they can route you to the right screening method from the start.

Key Takeaways

• Tell the TSA officer about your medical device before screening begins, and show them your device documentation or manufacturer's letter.
• Most medical devices do not need to be removed during screening, but some require a pat-down or alternative screening instead of a scanner.
• Devices with metal components or battery-powered equipment may not be safe to pass through standard metal detectors or X-ray machines.
• Carry your device documentation in your carry-on bag and keep it easily accessible at the checkpoint.
• If you travel frequently with a medical device, you can request TSA Cares assistance before your flight to arrange screening in advance.

Which devices need special screening at the checkpoint

Insulin pumps, continuous glucose monitors, and similar wearable devices can usually go through standard security screening without removal, but you should confirm with the TSA officer. Pacemakers, implantable cardioverter-defibrillators (ICDs), and neurostimulators should not pass through metal detectors — the officer will use a pat-down instead. If you have one of these implanted devices, mention it immediately so screening does not delay your line.

Ostomy supplies, catheters, and other medical equipment in your carry-on bag do not trigger special rules — they go through the X-ray machine like any other item. Medications in liquid or gel form (like insulin or certain topical treatments) are exempt from the 3.4-ounce liquid limit if they are medically necessary, but you do need to declare them to the officer.

Mobility aids like wheelchairs, walkers, and canes go through screening but do not need to be removed. If your device has a battery, tell the officer — some batteries require special handling. Oxygen tanks and CPAP machines can travel in carry-on or checked baggage depending on the device type and airline rules, so check with your airline before you arrive at the airport.

Documentation you should carry with you

Most medical device manufacturers provide a wallet card or letter that describes your device, its model number, and whether it is safe to pass through security screening. Carry this document in your carry-on bag, not in checked luggage, so you have it at the checkpoint. If your device came with no documentation, ask your doctor or the device manufacturer to write a letter on letterhead describing the device and any screening restrictions.

For implanted devices like pacemakers, your implant card from the hospital or clinic serves the same purpose. Keep it in your wallet or carry-on. If you do not have an implant card, contact the facility where the device was placed and request one — they can usually mail or email it to you within a few days.

Prescription documentation for medications that accompany your device (like insulin or injectable medications) is also useful to have on hand, though not always required. A copy of your prescription or a letter from your doctor stating the medication is medically necessary can prevent questions if a TSA officer is unfamiliar with your specific situation.

How to prepare before you travel

If you use TSA Cares, you can notify the TSA about your medical device up to three business days before your flight. TSA Cares will contact you to confirm your needs and alert the checkpoint staff at your airport, so screening can be arranged in advance. This is especially useful if you have a complex device or if you are traveling through an unfamiliar airport.

To use TSA Cares, visit the TSA website or call the TSA Cares line with your flight information and a description of your device. You do not need to provide medical records or proof of diagnosis — just tell them what device you have and what screening method works best for you. The TSA will note your needs in their system so the officer at your checkpoint knows what to expect.

Even if you do not use TSA Cares, arrive at the checkpoint early enough to allow extra time for device screening. Most medical device screening takes only a few extra minutes, but it is better to have a buffer than to rush. Pack your device documentation in an easy-to-reach pocket of your carry-on so you can hand it to the officer without digging through your bag.

What happens if your device triggers an alarm

If your device sets off a metal detector or scanner alarm, the TSA officer will perform a pat-down to determine the source. This is routine and does not mean there is a problem with your device or your travel plans. Tell the officer where the device is located on your body so they know what they are feeling during the pat-down.

If the officer is unfamiliar with your specific device, show them your documentation. Most officers are trained to recognize common medical devices, but having the manufacturer's letter or wallet card speeds up the process and prevents misunderstandings. If the officer still has questions, they can contact their supervisor or the TSA's medical device specialist for guidance.

In rare cases, an officer may need to perform additional screening or ask you to step aside while they consult with a supervisor. This is not a sign that you are being denied travel — it is a precaution to ensure both your safety and airport security. Stay calm and cooperative, and the process will move forward.

Traveling internationally with medical devices

International airports have their own security rules, which vary by country. Some countries have stricter rules about implanted devices or wearable electronics than the TSA does. Before you travel outside the United States, contact your airline and the airport security authority in your destination country to learn what screening methods they use.

Carry multiple copies of your device documentation — one in your carry-on, one in your checked bag, and one in your wallet. International security officers may not be as familiar with U.S. medical devices, so having clear documentation in English and, if possible, in the language of your destination country can prevent delays.

Some countries require advance notice of medical devices, especially implanted ones. Check the embassy or consulate website for your destination country, or contact your airline's medical services department. They can tell you what paperwork or notifications are needed before you depart.

Storing and protecting your device during travel

Keep your medical device in your carry-on bag, not in checked luggage. Cargo holds are unpressurized and unheated, which can damage batteries and sensitive electronics. If your device is wearable and stays on your body, you do not need to remove it for flight — it can remain in place during takeoff and landing.

If your device requires power, bring the charger and any necessary cables in your carry-on. Check your airline's rules about battery-powered devices in carry-on bags — most allow medical device chargers, but some have restrictions. Bring extra batteries if your device uses them, and store them in your carry-on as well.

During the flight, keep your device accessible in case you need to adjust it or troubleshoot a problem. If your device malfunctions during travel, contact the airline crew immediately. They are trained to handle medical emergencies and can provide assistance or divert the flight if necessary.

Frequently Asked Questions

Can I wear my insulin pump through the metal detector?

Yes, most insulin pumps can stay on your body during screening. Tell the officer you are wearing a pump before you approach the metal detector. If the pump triggers an alarm, the officer will perform a pat-down instead. Bring your pump documentation so the officer knows what they are looking at.

What if I have a pacemaker or ICD?

Do not go through a metal detector with a pacemaker or ICD — tell the officer immediately, and they will use a pat-down instead. Bring your implant card from the hospital. The TSA is trained to screen people with implanted devices, and the process is routine.

Can I bring my CPAP machine on the plane?

Yes, CPAP machines are allowed in carry-on or checked baggage. Check with your airline about their specific rules, as some have size or weight limits. If you bring it in carry-on, it goes through the X-ray machine like any other device. Bring the power cord in your carry-on so you can use it during the flight if needed.

Do I need a prescription letter for my medical device?

A prescription letter is not required, but it is helpful to have. A letter from your doctor or the device manufacturer describing the device and any screening restrictions can prevent confusion at the checkpoint. Most device manufacturers provide wallet cards that serve the same purpose.

What if the TSA officer does not know about my device?

Show them your device documentation — a manufacturer's letter, wallet card, or implant card. If they still have questions, they can contact a supervisor or the TSA's medical device specialist. Stay calm and cooperative, and the officer will work with you to find a screening method that is safe for both you and airport security.
