Summary & Overview
HCPCS S1031: Continuous Noninvasive Glucose Monitor Rental
HCPCS Level II code S1031 represents the rental of a continuous noninvasive glucose monitoring device, including the sensor, sensor replacement, and download for monitoring. This code matters nationally as continuous glucose monitoring advances change diabetes management, enabling remote monitoring and frequent data capture without invasive blood draws. Coverage and billing for device rentals affect access to real-time glucose data for patients with diabetes and influence how clinicians incorporate device-generated data into care.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what S1031 covers clinically and operationally, payer coverage patterns where available, and typical sites of service for device rental and monitoring. The publication summarizes how S1031 is used in ambulatory, home, and remote monitoring contexts and highlights common billing considerations tied to rental equipment and data services.
The report provides benchmarks and policy context relevant to billing for continuous glucose monitoring rentals, notes common modifier usage where applicable, and outlines gaps where input data is not provided. Data not available in the input is explicitly noted so readers understand limitations of the source material.
Billing Code Overview
HCPCS Level II code S1031 describes a continuous noninvasive glucose monitoring device rental, which includes the sensor, sensor replacement, and data download for monitoring. The description indicates the device is provided on a rental basis rather than as a purchase.
Service type: Durable medical equipment rental and monitoring service
Typical site of service: Outpatient or ambulatory settings, home use, or other noninpatient environments where continuous glucose monitoring is managed remotely or during clinical follow-up
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with type 1 diabetes and high glycemic variability is evaluated in an outpatient endocrinology clinic. The clinician determines that continuous noninvasive glucose monitoring would help optimize insulin dosing and detect nocturnal hypoglycemia. The clinic arranges rental of a continuous noninvasive glucose monitoring device that includes the sensor, sensor replacement, and the ability to download data to a monitor. A diabetes educator instructs the patient on device application and troubleshooting, the device is placed in clinic, and a rental agreement is documented in the medical record. Over the rental period the device transmits or downloads glucose trend data; the clinician reviews and interprets the downloaded data during a follow-up visit or remote review. If the clinician performs formal interpretation and medical decision-making on the downloaded data, an appropriate CPT code for physician interpretation is reported in addition to S1031 for the device rental. Typical sites of service include outpatient clinics, endocrinology practices, diabetes education centers, and home use with initial setup performed in an outpatient facility. The patient scenario includes documentation of indication (for example, recurrent hypoglycemia, poor glycemic control despite therapy changes, or evaluation for insulin pump initiation), informed consent for rental, start and end dates of rental, device serial numbers, and record of downloaded data and clinician interpretation when billed separately.
