Tissue Expander Fills for Breast Reconstruction

Question:

I was wondering if procedure code 11954 (Subcutaneous injection of filling material (eg, collagen); over 10.0 cc) could be billed on a claim when a expander fill is performed on the breast?

Answer:

CPT 11954 is not appropriate to use for a tissue expander fill. Tissue expander fills, when performed during the global period, are included in your postoperative care and not separately billable. This activity is included in your E&M code for the service provided when performed outside the global period.
