The Key Points to Keep in Mind When Billing CPT® Code 99458 for Remote Patient Monitoring


CPT® code 99458 covers the additional time your clinical team (or outsourced team) invests in monitoring patients after the 99457 time requirements have been met.

Here are the most important things you need to know to bill CPT® Code 99458 correctly using Vianova’s RPM platform.


Who Can Order 99458 and Provide Clinical Monitoring Services?

Like all Remote Physiologic Monitoring (RPM), a physician or other qualified healthcare provider (QHCP) can order RPM for the patient when they believe the prescription is medically necessary. Like 99457, the monitoring can be conducted by clinical staff under general supervision of the physician or QHCP. This means clinical staff, including nurses, can be remote or outsourced. Medical assistants (MAs) may qualify as clinical staff, but this can vary based on state law.

If a physician or QHCP conducts the monitoring, they may be eligible to bill at a higher reimbursement rate using CPT® code 99091.


What Activities Contribute to Clinical Monitoring?

The same activities that contribute to clinical monitoring for 99457 also count for 99458 monitoring time, including monitoring and analyzing patient data, patient communication, patient education, coordination with other care team members, and updating a patient’s care plan.


Time Requirements

99458 can be billed once you have met the requirements (20 minutes of engagement and one live synchronous call) for 99457. In other words, you can bill 99458 for minutes 21-40 of medically necessary patient engagement. You can also bill 99458 twice if you meet the 20 minute requirement, or for minutes 21-40. Note: you must have a second live or synchronous call to bill 99458.


99458 Code Dependencies and Billing Frequency

99458 can only be billed in conjunction with 99457. Both 99457 and 99458 can be billed even if the requirements for 99454 are not met. CMS has not placed a limit on the number of times 99458 can be billed in a calendar month, but any time spent engaging with the patient should be medically necessary.


Reimbursement Rates

According to the CMS CPT© Guidebook, Professional Edition 2023, the national average reimbursement rate for 99458 is $38.68, but rates will vary by geography and location. Vianova’s RPM platform makes it easy to track and bill for these services, ensuring that you receive the maximum reimbursement for your efforts.
