What is an INR machine?

In short, an INR machine is a device used to measure the time it takes for your blood to clot. This number helps you and your doctor understand how well your blood is clotting, which can be important to know if you are taking a blood thinner. If your INR levels are too high or too low, there could be serious health consequences.

How to get a Medicare coverage for an INR machine?

Medicare coverage for an INR machine is available through the Durable Medical Equipment (DME) benefit. To qualify, you must have a doctor’s prescription and be enrolled in Medicare Part B. Additionally, the machine must be deemed medically necessary and you must use it under the supervision of a doctor or other healthcare provider.

What are the benefits of using a home INR machine?

Using a home INR machine can save you time and money, as it eliminates the need for frequent trips to the doctor's office for testing. Additionally, you can get your results quickly, which can be important if your INR levels are outside of the desired range.

How to use an INR machine

Using an INR machine is easy and straightforward. First, you must place a finger or toe into the machine’s device to draw a sample of your blood. The machine will then analyze the sample to determine your INR reading. You can also use an app on your phone to track your readings.

It's important to note that INR machines are not for everyone and should only be used under the supervision of a healthcare provider.

Tips for staying within your target range

To make sure you stay within your target range, be sure to take your blood thinner as prescribed. Additionally, maintain a healthy lifestyle with regular exercise and a balanced diet. Finally, if you experience any side effects or changes in symptoms, be sure to contact your doctor right away.


If you are a Medicare beneficiary and think you need an INR machine, speak to your doctor and/or healthcare provider about whether it is the right choice for you. This content is for informational purposes only. If you have any Medicare questions, talk with an expert at Fair Square Medicare today.
