Below are some of the current codes for re-
mote patient monitoring. The first three codes

(99453, 99454, and 99457) are specific to the
iCare Home tonometer. Note that payment for
CPT codes can vary depending on where your
practice is located.
Initial setup. (CPT code 99453: $18.77) This
is a one-time claim and reimbursement for
instructing the patient on performing home
monitoring and transmitting data with the
iCare Home tonometer.
Device. (99454: $62.44/month) This is a
monthly claim and reimbursement for the
equipment and software used to perform the
remote patient monitoring test with the iCare
Home tonometer.
Monitoring. (99457: $51.61/month) This is a

monthly claim and reimbursement for commu-
nicating with the patient and managing and/or

coordinating for a cumulative total of 20 min-
utes/month about the iCare Home tonometer.

In-person or telehealth visit. (99212-
99215/92012-92014) When an office visit or
telehealth visit is needed, submit extra visit
code(s) as usual. Note: Eye visit codes 92012-
92014 were temporarily added by CMS for
telehealth use for the public health emergency
Evaluation and Management (E/M). (99213:
<$93 or 99214: <$132) This is reimbursement
for a follow-up visit, whether virtual or in
person, meeting 2021 E/M documentation
guidelines. Note: E/M fees vary by region.
The fees listed here are for Dallas, Texas.

This is simple to do. First set both Rests to about the "9" mark by rotating each dial and lining up the arrows to the appropriate number on the HOME. Once you do this, attempt one measurement. If it there is no error, you are ready! If not, follow the audio ques the device gives, Short beeps for too close, and long beeps for too far away. You will adjust each dial accordingly. the probe should be about 1/4-1/2" away from the eye. (see photos in the start up guide).

The safety and effectiveness of the Icare HOME tonometer has not been evaluated for
patients with:
1) High corneal astigmatism >3d
2) History of prior incisional glaucoma surgery or corneal surgery including corneal
laser surgery
3) Corneal scarring
4) Central corneal thickness greater than 0.60mm or less than 0.50mm
5) Known history of difficulty in obtaining Goldmann IOP measurements or any
factors that might contribute to inaccurate Goldmann IOP measurements (e.g. lid
squeezing or tremor

By taking measurements at home, you and your doctor will learn how your IOP varies at different times throughout the day. This data can guide treatment decisions, medication changes and be utilized to better understand the risks to your vision. This data will be shared with your doctors upon completion and return of the iCare HOME and can be invaluable to helping you manage your disease.

YES it is safe and NO, there are no Risks. The Icare HOME is safe when used according to its indications for use and in accordance with its labeling. It is approved for use by patients at home by the FDA under rigorous testing. There is minimal risk to the patient. It is safe for use by practically everyone. If you have any specific concerns, please consult with your ophthalmologist.

NO. The probe briefly touches the cornea without the need for any eye drops and without one feeling anything. The HOME records a measurement faster than you can blink.

YES. You are required to submit a prescription to either rent or purchase the HOME.

Renting keeps costs low and allows you to get a snapshot of your IOP to discover if your pressures are a factor influencing your glaucoma. It can also be covered by your HSA. Buying a HOME is more money upfront but allows you to track your pressures continually over an extended period of time.

You can use the included phone to upload your data to the iCare Clinic platform, where you can view your measurements on a graph and table. If you want to do this, just let us know and we can send you an email link to login to the online software. If you don’t care to track your measurements, they will be downloaded when you send your HOME back to us and we will email you (and your doctor) a color copy of your results.

Right now it is about $250/week to rent and $2650 to purchase.

Your doctor will receive a color copy of your results emailed to them once your rental period ends.

YES. The Home can store thousands of measurements, and will keep them secure until they are uploaded to the Clinic software.

Once you complete the rental process, it usually only takes a few days to receive your device on your doorstep, nationwide.

Yes. We currently have a platform set up to be able to "host" you through our company, keeping your doctor and your device connected. Just let us know after your purchase and we will set this up for you!

NO. iCare is simply the manufacturer of the device. They are not responsible for, nor equipped to handle HOME rental questions. Please do not contact them. MyEYES is always available to walk you through any question or concerns you may have. Send us an email or fill out a contact form from the website.

If you are having issues with a rental or a purchase, you should always contact us first so we can help!

YES. Sometimes your doctor doesn’t want to worry about keeping track of your measurements whether short term or long, they are most interested in the data you will be collecting. So long as they write you a prescription for the device as a patient you can still rent or purchase your own device. You can then present your data to them at your next appointment.

Initially you will be able to figure out your measurements once you watch the instructional videos regarding the proper positioning of your HOME. You can always adjust them out to around 9 on top and bottom to start. An easy way to determine the correct distance is making sure that the tip of the probe is just beyond your eyelashes or approximately ½” from your cornea. The device will give you short beeps if you’re too close and long beeps if you are too far away. Once you find the correct position, don’t adjust them anymore, just carefully place your HOME in the case and gently close the lid. You can keep it stored this way to preserve your adjustments.

YES. You can find the iCare HOME app on google play. The app is designed to be a quick resource guide you can access directly from your phone or tablet.

Please contact us for any questions you may have. You can do this via our website; us or email us at We would be more than happy to help.

You can use a probe to complete unlimited daily measurements on each eye if kept clean and secure in the device and in its case. Some patients use the same probe for days at time with no problems. iCare suggests changing probes after each measurement to keep them clean.

YES. Under normal circumstances, the HOME device can be used with no risk to the patient. However, If you have any concerns or questions you should consult with your ophthalmologist.

YES. One of the biggest advantages of the HOME is that it is portable. It comes in a protective case and can be taken just about anywhere. Whether you are taking measurements at home or if you take it on a hike, your HOME is ready to record measurements.

Simply repackage the HOME in the box it came with and attach the return label. Then drop it off at any USPS or UPS store the next business day after your rental period ends.


While looking directly at the probe, you should see a nice concentric green circle. This indicates that it is lined up with your pupil correctly. You can then Hold the measurement button down for 6 rapid measurements, or push it each time for individual ones. The Device will give you a green check mark and long beep to let you know you completed the measurement correctly.

NO. The HOME knows which eye you are measuring. It doesn’t matter which eye you start with. You just have to remember that you must complete 6 measurements and get a long beep with the “done” green check mark light, before moving to the next eye or repeating the measurement on the current eye. You can take as many measurements from either eye as often as you like.

YES. If you own an Android tablet or phone, you can simply go to the google play store and download the iCare Patient app. Once installed and your phone or tablet is connected to the internet you use the included cable plugging the “Host” end into your phone or tablet and the “Cable Connection” into the HOME device (the port can be found on the bottom of the HOME under a tiny black rubber pull tab). The HOME will beep & light up , the app will automatically open and upload the measurements directly to the iCare Clinic Software within a few seconds. It will then prompt you to unplug the device. (Note: You CANNOT use the option if you own an apple iphone)

YES. This can be ideal if you have someone available to help you take measurements. The process is the same for positioning the HOME.

YES and NO. With a purchase you get 1-year free access to the software. After that it is $69/year. If you are renting the device, you will have access to your data for up to 90 days from the end of your rental period. Besides the copy of your results we furnish you with, you can download and print your results from the Clinic software.

YES. iCare has a program called LINK that you can download to your computer. This software will keep track of all your measurements just like the online platform. For a link you can check out the resources page on our website under owners help.

You can go to the iCare-world website and click on the button at the top labeled “order more probes”. They are about $50/box of 50.

Simply contact us via and let us know what we can do to help.

NO problem, you can find our Terms and Conditions and Privacy Policy right here by clicking either one!

Returns are generally NOT accepted due to the fact that this is a medical device. However within 30 days, if it is unopened, you may return it in it's original packaging and get a full refund minus processing and restocking fees of %10. If there is a special circumstance, please contact us for further assistance.

The HOME tonometer comes with a year manufacturer warranty. At the time of purchase you can also purchase an extended warranty service plan through iCare. Currently we are working with a third party to set up an additional warranty service.

Simply take your contact lenses out and wait a few minutes and then take your measurements like normal. For some people they measure their numbers with and without their contacts in and note the difference, and then just add that to all their measurements while wearing them so they don't have to take them out all the time.  Note* you cannot use this device if you use Scleral Lenses. (you will get inaccurate readings)

YES. Under normal circumstances, rebound tonometry is not effected but Lasik surgery. An interesting study can be found here.

It is widely accepted that central corneal thickness is a predictive factor for the risk of glaucoma progression. Recent evidence shows that corneal hysteresis also provides valuable information for several aspects of glaucoma management. In fact, corneal hysteresis may be more strongly associated with glaucoma presence, risk of progression, and effectiveness of glaucoma treatments than central corneal thickness.

Corneal Hysteresis, a variable that is thought to be associated with the risk and progression of glaucoma.

Low corneal hysteresis is associated with optic nerve and visual field damage in glaucoma and the risk of structural and functional glaucoma progression. In addition, hysteresis may enhance intraocular pressure (IOP) interpretation: low corneal hysteresis is associated with a larger magnitude of IOP reduction following various glaucoma therapies. Corneal hysteresis is dynamic and may increase in eyes after IOP-lowering interventions are implemented.

To better understand the role of corneal properties and intraocular pressure (IOP) in the evaluation of primary open-angle glaucoma (POAG); and to determine the feasibility of identifying glaucomatous optic neuropathy (GON) using IOP corrected and uncorrected for corneal biomechanics. This is called IOPcc.

Although there are no specific studies as of yet to determine how rebound tonometry factors into this, but if you are going to use the device in addition to this information, consult with your doctor.
