What is CPT Code 99458?
CPT Code 99458 is the billing code for each additional 20 minutes of clinical staff time and interactive communication for a patient’s remote patient monitoring program. Code 99458 varies slightly from other codes as it is considered an add-on to CPT Code 99457, rather than being considered a standalone code.
To qualify for reimbursement for Code 99458, physicians must first meet the 20 minutes of service requirement for 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.
What services are required to bill code 99458?
Similar to CPT Code 99457, Code 99458 requires interactive communication in order to be added on to reimbursements.
