About 0448T: Implantable glucose sensor removal and replacement
Report this Category III service when a clinician removes an implanted glucose sensor and inserts its replacement during the same service.
This service covers removal of an existing subcutaneous implantable glucose sensor and insertion of its replacement. It is typically performed in an office by a clinician trained to manage the implantable continuous glucose monitoring system, such as an endocrinology provider. The replacement may be planned when the sensor reaches the end of its wear period or performed when a sensor needs replacement for another documented reason.
Report 0448T for the combined removal-and-replacement service, rather than separately reporting removal and insertion for the same replacement. Documentation should identify the implanted sensor, the reason for replacement, and completion of both removal and insertion. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.

0448T billing questions
When should 0448T be used instead of 0446T or 0447T?
Use 0448T when the existing implantable glucose sensor is removed and a replacement is inserted. Use 0446T for insertion only and 0447T for removal only.
Should removal and insertion be billed as separate codes for one replacement?
No. Report 0448T for the combined removal-and-replacement service rather than splitting those steps into 0447T and 0446T.
Can modifier 50 be reported if the patient has sensors on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
Is same-day postoperative care included?
Yes. The code has a 0-day global period, which includes same-day preoperative and postoperative care.
What documentation supports reporting 0448T?
Document the implanted sensor being removed, the reason for replacement, and that both removal and insertion were completed.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
