Summary & Overview

CPT 98977: RTM Musculoskeletal Device Supply (16-30 Days)

CPT code 98977 covers the supply of one or more devices used for remote therapeutic monitoring (RTM) of the musculoskeletal system when monitoring occurs for 16 to 30 days in a 30-day period. This code defines a discrete supply component of RTM workflows and matters nationally as remote care and digital therapeutic tools expand across ambulatory and home-based settings. Payers increasingly address RTM device supply, and clear coding supports accurate claims and consistent benefit determinations.

Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service and typical sites of care, followed by payer coverage patterns, commonly reported modifiers, and benchmarks or policy updates where available. The publication also situates 98977 within broader RTM billing practices and explains operational considerations for device provisioning and claim submission.

Billing Code Overview

CPT code 98977 describes the supply of one or more devices for remote therapeutic monitoring (RTM) of the musculoskeletal system when monitoring occurs for 16 to 30 days within a 30-day period. The service is focused on therapeutic monitoring rather than diagnostic testing and is intended to support remote management of musculoskeletal conditions through data collected by the supplied device(s).

Service type: Remote Therapeutic Monitoring (RTM) device supply for musculoskeletal monitoring
Typical site of service: Remote or home-based monitoring; devices are supplied by the provider for use outside of the clinical setting.

Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.

Clinical & Coding Specifications

Clinical Context

A 54-year-old patient with chronic low back pain following lumbar strain is enrolled in a remote therapeutic monitoring (RTM) program. The clinician supplies a wearable musculoskeletal monitoring device to capture range-of-motion, activity, and adherence with prescribed home therapeutic exercises. The device is set to transmit physiologic and movement data over a 30-day period. For a billing period in which monitoring data is captured for 16 to 30 days within the 30-day span, the provider supplies the device and documents device distribution, patient instruction for use, device pairing, and remote therapeutic monitoring plan of care. Clinical workflow includes device selection and provisioning, patient education and consent, setup and verification of data transmission, periodic review of incoming RTM data, asynchronous patient messaging or phone outreach as needed, and documentation of monitoring days and any clinical interventions triggered by the data. Typical site of service is outpatient clinic, ambulatory care center, or the patient’s home with device supply initiated by the clinic and remote data review performed by the treating clinician or designated clinical staff.
