image_pdfimage_print

Question:

For an occluded AV graft, I made one puncture to shoot contrast and evaluate a problem with the graft and billed 36147. When can the add-on code +36148 be used in addition to 36147?

Answer:

The CPT states the 36148 is used for “additional access for therapeutic intervention.” Therefore, the purpose of that second puncture must be to treat an occlusion or problem with the graft; for example, performing an angioplasty or stent.
