Doctor With Laptop

CPT Code 99458 is a remote patient monitoring billing code used to reimburse practices for remote care services through Medicare. CPT Code 99458 varies slightly from other codes as it is considered an add-on to CPT Code 99457, rather than being considered a stand alone code. In order to qualify for reimbursement for CPT Code 99458, physicians must first meet the 20 minutes of service requirement for CPT Code 99457, then bill for each following additional 20 minutes of service. This code helps to provide for practices who support remote patients with extra care and additional services by allowing practices to bill for services provided beyond the required 20 minutes. Remote patient monitoring companies such as 100Plus make interactive remote patient care necessary for Medicare reimbursement easy and accessible.

What services are required for CPT Code 99458?

Similar to CPT Code 99457, CPT Code 99458 requires interactive communication in order to be added on to reimbursements. This interactive communication is defined as “a conversation occurring in real time that includes synchronous, two-way interactions that can be enhanced with video or other kinds of data.” Additionally, the CMS clarified that the 20 minutes of service time required to bill for both 99457 and 99458 “should include care management services and synchronous, real-time interactions.” Therefore making it clear that, while interactive communication contributes to the required 20 minutes, it is not the only activity that should be included in the total time as overall care management can contribute as well.
