TSA PreCheck When You Travel With a Disability or Medical Device

How TSA PreCheck works for travelers with disabilities

TSA PreCheck lets you move through airport security faster by keeping shoes, belts, and light jackets on, leaving laptops and liquids in your bag, and using a dedicated screening lane. For travelers with disabilities or medical devices, the main benefit is predictability: you know what to expect, you can request the same screening officer, and you can bring a companion through security without buying them their own membership.

The program costs $78 to $85 for five years, depending on how you pay. You do not need a disability diagnosis to join — you apply like anyone else, go through a background check, and get approved or denied based on criminal history and immigration status, not on your medical condition. Once approved, your membership works at over 200 U.S. airports and on most major airlines.

TSA PreCheck is separate from TSA Cares, which is free and designed specifically for travelers with disabilities, medical conditions, or injuries who want to talk through their screening options before they arrive at the airport. Many people use both: they call TSA Cares a few days before travel to explain their needs, then use their PreCheck membership to move through the line faster on the day itself.

Key Takeaways

• TSA PreCheck costs $78 to $85 for five years and speeds up security screening by letting you keep shoes and jackets on and leave electronics in your bag.
• You can bring a companion through the PreCheck lane with you at no extra cost, which is useful if you need assistance during screening.
• TSA PreCheck approval is based on background checks, not on disability status, so having a medical condition does not affect your chances.
• You can request the same officer for screening each time you travel, which helps if you have anxiety or need consistency in how your device or condition is handled.
• TSA Cares (free) and TSA PreCheck (paid) work together — call TSA Cares before your trip to explain your needs, then use PreCheck to move through security faster.

What screening looks like with TSA PreCheck

In the PreCheck lane, you move through a metal detector instead of a full-body scanner, which matters if you have a pacemaker, insulin pump, or other implanted device that you want to avoid. You keep your shoes on unless the officer asks you to remove them. Medications, medical devices, and mobility aids do not need to come out of your bag or off your body — you can go through the metal detector with your cane, walker, or wheelchair, and the officer will not ask you to remove it.

If you have a prosthetic limb, joint replacement, or metal implant, tell the officer before you step up to the metal detector. The machine will alarm, and the officer will pat down the area around the device instead of sending you to a full-body scanner. This is routine and happens dozens of times a day; the officer has seen it before.

If you need to remove clothing for screening — which happens rarely and only if the officer suspects a threat — you can ask for a private screening room and bring a companion or TSA officer of your gender in with you. You can also ask for a same-gender officer at any point during screening.

Medical devices and medications you can bring through security

You do not need to remove or separate out medications, inhalers, EpiPens, insulin, or insulin pumps. You do not need to remove mobility aids, braces, or compression garments. Ostomy supplies, catheters, and colostomy bags can stay with you. If you wear a continuous glucose monitor, hearing aid, or other wearable device, you can keep it on during screening.

Liquid medications in containers larger than 3.4 ounces are allowed — this is one of the few TSA rules that changes for medical need. Bring a label or prescription bottle to show the officer, or call TSA Cares before your trip and they will note it in your file so the officer knows to expect it.

If you have a device that cannot go through a metal detector — some older pacemakers, for example — tell the officer before screening begins. They will use a handheld metal detector wand instead, or they will pat you down. This takes a few extra minutes but is a normal alternative.

How to request a consistent screening officer

When you go through PreCheck screening, you can ask the officer at the entrance to the lane if the same person will be screening you that day. If yes, ask them to note your name and any specific needs — for example, "I have a prosthetic leg and prefer not to remove it" or "I have anxiety and do better with the same person each time." They will make a note in their log.

On future trips to the same airport, arrive early enough to ask for that officer by name if they are working that day. Not every officer will be there every day, and you cannot reserve them in advance, but many travelers with disabilities report that asking works more often than not. If your regular officer is not there, the new officer will not have your note, so be ready to explain your needs again.

This is not an official TSA program — it is a courtesy that individual officers can offer. It works best at smaller or medium-sized airports where the PreCheck team is smaller and more stable. At very large airports, consistency is harder to achieve.

TSA PreCheck versus TSA Cares: which one do you need

TSA Cares is free and designed to walk you through your specific screening needs before you travel. You call 855-787-2227 at least 72 hours before your flight and talk to someone about your disability, medical device, or injury. They note everything in a file that travels with you to the airport, and the screening officer pulls up that file when you arrive. This is especially useful if you have a condition that is not obvious, or if you need to explain something complicated that you do not want to repeat at the security line.

TSA PreCheck is paid ($78–$85 for five years) and speeds up the screening process itself. You move through a faster lane, keep more items on, and can bring a companion. It does not replace TSA Cares; it works alongside it.

If you travel once or twice a year and have a straightforward disability or device, TSA Cares alone may be enough. If you travel more often, or if you want to move through security faster and have more control over the screening process, PreCheck is worth the cost. Many travelers do both: they use TSA Cares to set expectations before the trip, then use PreCheck to move through the line faster on the day.

How to sign up for TSA PreCheck

Go to the TSA PreCheck website (tsa.gov/precheck) and create an account. You will answer questions about your background, criminal history, and immigration status. You do not mention your disability or medical condition — the form does not ask for it, and it does not affect approval.

After you submit the form, you will be scheduled for an in-person appointment at an enrollment center. Bring your passport or driver's license, proof of citizenship or immigration status, and a second form of ID. The appointment takes about 10 minutes and includes a fingerprint scan. You will pay the fee at the appointment ($78 to $85 depending on the state and payment method).

Approval usually takes 3 to 5 business days after your appointment. You will receive an email with your Known Traveler Number (KTN). Add this number to your airline profile before you book your next flight, and you will see "TSA PreCheck" on your boarding pass. If you do not add it to your profile, the airline will not know you have it, and you will not get the faster lane.

What to do if you are denied TSA PreCheck

TSA PreCheck denial is rare and is based only on criminal history, immigration status, or false information on your application. If you are denied, you will receive a letter explaining the reason. You can request a review of the decision by mail — the letter will tell you how.

Denial does not prevent you from traveling or going through regular security screening. It only means you cannot use the PreCheck lane. You can still use TSA Cares to set up your screening needs before your trip, and you can still request a private screening room or a same-gender officer during regular security screening.

If you believe the denial was a mistake — for example, if you have a common name and were confused with someone else — include documentation with your appeal. This process takes several weeks.

Frequently Asked Questions

Can I bring my service dog through TSA PreCheck screening?

Yes. Service dogs do not need to go through the metal detector or be screened separately. They stay with you throughout the process. If the dog alarms the metal detector for any reason, the officer will pat down the dog instead of sending you to a scanner. Emotional support animals and pets are not allowed in the PreCheck lane and must go through regular screening.

What if my wheelchair or mobility device alarms the metal detector?

The officer will pat down the device and the area around it. You do not need to remove it or transfer to another chair. If the device has a battery or electronic components, tell the officer before you go through — they may use a handheld wand instead of the metal detector to avoid damaging it.

Do I have to tell the TSA officer about my disability when I go through PreCheck screening?

No. You only need to tell them about specific things that affect screening — a metal implant, a device that cannot go through a metal detector, or a medication in a container larger than 3.4 ounces. If you called TSA Cares before your trip, they will have a note in your file, and the officer will already know.

Can my companion go through TSA PreCheck with me if they do not have their own membership?

Yes. One companion can go through the PreCheck lane with you at no cost. This is useful if you need help during screening or if you travel with a caregiver. Your companion does not need their own PreCheck membership or boarding pass — they just need to be with you when you enter the lane.

What happens if I lose my TSA PreCheck card before it expires?

You can still use PreCheck with just your Known Traveler Number (KTN) — you do not need the physical card. Add your KTN to your airline profile, and it will show on your boarding pass. If you want a replacement card, you can request one through the TSA PreCheck website, though it is not necessary for screening.
