Glucose monitoring procedure
About 0447T: Implantable glucose sensor removal
Report removal of an implanted subcutaneous glucose sensor, such as an implantable continuous glucose monitor, when the sensor is extracted without replacement.
This service covers a procedure to remove an implantable glucose sensor from subcutaneous tissue, commonly from the upper arm. A clinician trained in implantable continuous glucose monitoring procedures, often in an endocrinology practice, makes an incision, locates the sensor, and extracts it; surrounding tissue may be removed as needed. It is distinct from taking off an external CGM sensor, which is worn on the skin.
Report 0447T when the encounter is for sensor removal alone. If the clinician removes the sensor and inserts a replacement during the same procedure, use 0448T instead. Document the implanted device, removal site, and that the sensor was actually extracted. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure payment reduction. Modifier 50 is not appropriate for this single-sensor removal. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

0447T billing questions
Should 0447T or 0448T be reported when the sensor is replaced?
Use 0447T for removal alone. When the clinician removes the old implantable sensor and inserts a replacement in the same procedure, report 0448T.
Can 0447T be reported for removal of an external CGM sensor?
No. This code is for removing an implanted subcutaneous sensor, not detaching an external sensor worn on the skin.
What documentation supports reporting 0447T?
Document the implantable sensor, its removal site, and the procedure establishing that the sensor was extracted. If a replacement was inserted during the same procedure, consider 0448T instead.
Can modifier 50 be used for bilateral sensor removal?
CMS identifies bilateral adjustment as inappropriate for this code. Report the removal of the individual implanted sensor without modifier 50.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure. CMS assigns a 0-day global period.
Can an assistant surgeon or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
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.
