CPT 98981: Remote Therapeutic Monitoring Management, 20-Min Add-On

CPT code 98981 is an add-on code for remote therapeutic monitoring (RTM) management that captures each additional 20 minutes of physician or qualified healthcare professional time when RTM data are used and at least one real-time interactive communication with the patient or caregiver occurs during the month. The code enables reporting of extended clinical management time tied to RTM, reflecting growth in virtual chronic care and digital therapeutic oversight nationally.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of how CPT code 98981 is defined and operationalized, payer coverage considerations, and the clinical context for its use in ambulatory and telehealth settings. The publication summarizes common billing modifiers, typical service lines, and expected sites of service associated with RTM management.

The report outlines benchmarks and policy implications relevant to providers integrating RTM into workflows, highlights documentation and time-tracking elements intrinsic to the add-on structure, and summarizes payer approaches where available. Data not available in the input is clearly noted where applicable.

Billing Code Overview

CPT code 98981 describes an add-on remote therapeutic monitoring (RTM) service in which the provider manages a patient’s treatment using RTM data and conducts at least one real-time interactive communication with the patient or caregiver during the month. This add-on code represents each additional 20 minutes of physician or qualified healthcare professional time beyond the primary service.

Service Type: Remote Therapeutic Monitoring management with real-time patient interaction

Typical Site of Service: Ambulatory or virtual/telehealth settings where RTM data review and synchronous communication can occur

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with chronic low back pain enrolled in a remote therapeutic monitoring (RTM) program uses a wearable sensor and an app to transmit activity and pain-related metrics daily. The treating physiatrist reviews aggregated RTM data and adjusts the therapeutic plan. During the month, the clinician conducts at least one real-time interactive communication (video or telephone) with the patient to discuss symptom trends, medication tolerance, and changes to the home exercise program. The provider documents time spent managing the RTM data and the interactive encounter. When management time for the month exceeds the primary RTM service time, an additional 20-minute unit of clinician work is billed using 98981 as an add-on to the primary RTM service. Typical workflow: enrollment and device setup, daily data review by clinical staff, clinician review and decision-making, real-time patient communication, documentation of cumulative time and clinical actions, and billing of the primary RTM code with 98981 for each additional 20 minutes beyond the primary service.

CPT Code	Description	Relationship to This Procedure
`98980`	Remote therapeutic monitoring (RTM) treatment management services; initial 20 minutes of RTM care management services per month requiring at least one interactive communication with the patient/caregiver	Primary RTM service to which `98981` is an add-on for each additional 20 minutes.
`99457`	Remote physiologic monitoring treatment management services, first 20 minutes of clinical staff/physician/other qualified healthcare professional time in a calendar month requiring interactive communication	Alternative remote monitoring code for physiologic data; may be used in workflows where physiologic monitoring rather than therapeutic monitoring is billed.
`99458`	Remote physiologic monitoring treatment management services; each additional 20 minutes	Comparable add-on to `99457`, used when additional time is required for RPM rather than RTM.
`99091`	Collection and interpretation of physiologic data digitally stored and/or transmitted by the patient to the physician, requiring a minimum of 30 minutes of time	Used for non-RTM data interpretation workflows where time thresholds and payer rules differ; may be billed when criteria are met instead of RTM.
`97750`	Physical performance test or measurement (e.g., musculoskeletal function tests)	Often performed in conjunction with RTM programs to establish baseline function and track progress.
`99421`	Online digital evaluation and management service, for an established patient, for up to 7 days, cumulative time during the 7 days	May be used for asynchronous digital communications that complement RTM synchronous encounters.
