CPT 98977

🔹What is CPT Code 98977?

CPT 98977 is used to report the supply of remote therapeutic monitoring (RTM) devices for musculoskeletal system monitoring. These devices are used for scheduled recordings and/or programmed alert transmissions and must operate under a care plan ordered by a physician or qualified healthcare provider. The code is billed once per 30 days, assuming a minimum of 16 days of use.

​

💪 This code applies specifically to musculoskeletal therapy monitoring and does not include management or interpretation services.
