Your Guide To The New CPT Codes

The 2020 CPT codes for remote patient monitoring (RPM) and ketone testing are available to support adherence to clinical programs using the BIOSENSE® device, indicated for in-home ketone testing. The Centers for Medicare and Medicaid Services recognize the importance of remote patient monitoring services, and the power it has to minimize the gaps in our current healthcare system.

While CMS has not specified which types of technology are covered under the new CPT codes, the device used must be a medical device as defined by the FDA.

Here’s a quick and easy guide to the new CPT codes and the national average Medicare payment.
