Q28.2: Arteriovenous malformation of cerebral vessels

Q28.2, arteriovenous malformation of cerebral vessels, is listed as a covered diagnosis in 11 Medicare billing and coding articles that apply to 51 HCPCS Level II codes, including G0340 (Image-guided robotic linear accelerator-based stereotactic…), G0339 (Image-guided robotic linear accelerator-based stereotactic…), C8900 (Magnetic resonance angiography with contrast, abdomen). The articles come from 6 Medicare contractors. A listed diagnosis supports medical necessity only; coverage still depends on the LCD's criteria and on documentation in the medical record.
