C7B.8: Other secondary neuroendocrine tumors
C7B.8, other secondary neuroendocrine tumors, is listed as a covered diagnosis in 8 Medicare billing and coding articles that apply to 61 HCPCS Level II codes, including G0340 (Image-guided robotic linear accelerator-based stereotactic…), G0339 (Image-guided robotic linear accelerator-based stereotactic…), G0563 (Stereotactic body radiation therapy, treatment delivery…). The articles come from 3 Medicare contractors. A listed diagnosis supports medical necessity only; coverage still depends on the LCD's criteria and on documentation in the medical record.
