Endocrinology procedure

About 0446T: Implantable glucose sensor insertion

Report 0446T when a clinician places a subcutaneous implantable glucose sensor and activates the system for continuous glucose monitoring.

This service covers placing a glucose-monitoring sensor beneath the skin, activating the implantable system, and training the patient to use it. It is typically performed by a clinician trained in sensor placement, often in an endocrinology or diabetes practice. The sensor supports ongoing glucose monitoring for a patient with diabetes; this is an implanted device, not a wearable sensor placed on the skin. Placement commonly occurs in an office setting.

Report 0446T for the insertion service, with documentation identifying the implant, placement site, activation, and patient instruction. The same-day preoperative and postoperative care is included in this 0-day global service. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the remaining procedures are paid at 50%. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

0446T billing questions

How is 0446T different from 0447T?

0446T reports insertion and system activation. 0447T is for removal of an implanted glucose sensor without new sensor insertion.

When should 0448T be used instead?

Use 0448T when the service includes removing an existing implanted sensor and inserting a replacement sensor. 0446T is the insertion service without that combined removal.

Can patient training be billed separately?

Training associated with activation of the implanted sensor is part of the 0446T service. Document the instruction provided as part of the insertion and activation.

Can modifier 50 be reported for two implant sites?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

What documentation supports 0446T?

Document the implanted sensor placement, its site, system activation, and patient instruction. The record should distinguish insertion from removal-only or removal-and-replacement services.
