It wasn’t too long ago when patients taking warfarin (brand name Coumadin) were heading off to the lab or clinic every few weeks for an international normalized ratio (INR) blood test. Thanks to a small, portable device, patients on warfarin can now self-test with a finger prick drop of blood. There is more to self-testing than the ease and convenience, though. Patients are happier! Their quality of life improved because they can keep up with their activities – even travel, without the stress of making and keeping testing appointments.

Self-testing: Measurable difference when correct coding is reflected

This type of quality care and improved outcomes are making a measurable difference in the lives of our members. We want this success accounted for in the INR clinical quality measure and with your help, we can do it.  Use these codes to reflect INR In-home monitoring when noting the INR results for your patients.
