Question:
Is submucosal injection a required component needed to assign an endoscopic mucosal resection (EMR) CPT code for a ligation-assisted EMR?
Answer:
No, a submucosal injection is not a required component of the codes for digestive system endoscopy with EMR (45349, Sigmoidoscopy, flexible; with endoscopic mucosal resection, 45390, Colonoscopy, flexible; with endoscopic mucosal resection).
Coding for EMR procedures requires the performance of the following components: (1) a technique to lift the lesion; (2) demarcation of the lesion, often by creating a pseudopolyp out of tissue or any technique (including high definition white light, narrow band imaging, or by cautery) that allows clear visualization of the boundaries of the lesion; and (3) endoscopic snare resection.
If all three components listed above are not performed, it is not appropriate to report an EMR procedure. Likewise, ablation of the edges of the lesion, clipping of the defect, or other bleeding treatment applied to the same lesion are not reported separately when performing EMR.
