HCPCS Level II S9110: Home Telemonitoring, Monthly

HCPCS Level II code S9110 covers monthly telemonitoring services for patients in their homes, including equipment, software, connectivity, maintenance, and patient education. As home-based remote monitoring expands, S9110 represents an important billing pathway for services that support chronic disease management, post-discharge surveillance, and virtual care programs at scale. Nationally, such codes matter for integrating telehealth into routine care delivery and for aligning payment with remote care workflows.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, payer coverage considerations, common modifiers, and implementation context. The publication summarizes available benchmarks where present, highlights recent policy and coverage trends affecting home telemonitoring, and outlines clinical use cases and operational implications for health systems and vendors.

This report provides a practical reference for billing, coding, and care delivery teams seeking a national perspective on monthly home telemonitoring services and the administrative considerations tied to HCPCS Level II code S9110. Data not available in the input is noted where applicable.

Billing Code Overview

HCPCS Level II code S9110 describes telemonitoring of a patient in their home, billed per month. The service includes provision and maintenance of all necessary equipment, the computer system and connections, required software, and patient education and support.

Service type: Remote patient telemonitoring and home-based monitoring services
Typical site of service: Patient's home

Clinical Context

A 72-year-old patient with congestive heart failure (reduced ejection fraction), hypertension, and type 2 diabetes is enrolled in a home telemonitoring program billed monthly under S9110. The program supplies an integrated kit (blood pressure cuff, weight scale, pulse oximeter, cellular gateway), a cloud-based monitoring platform, and nursing oversight. The patient receives initial setup and education at home by a telehealth technician, daily automated data transmissions, and asynchronous review by a remote care team. Abnormal alerts (eg, rapid weight gain, sustained elevated blood pressure, low oxygen saturation) trigger nurse outreach by telephone or video and, if necessary, escalation to the supervising clinician for medication adjustment or in-person evaluation. Documentation includes informed consent for remote monitoring, device serial numbers, training confirmation, daily summary logs, alert reviews, outreach notes, and monthly service summary supporting the S9110 monthly telemonitoring charge.
