I73.9: Peripheral vascular disease, unspecified
I73.9, peripheral vascular disease, unspecified, is listed as a covered diagnosis in 10 Medicare billing and coding articles that apply to 29 HCPCS Level II codes, including G0127 (Trimming of dystrophic nails, any number), C8900 (Magnetic resonance angiography with contrast, abdomen), C8901 (Magnetic resonance angiography without contrast, abdomen).

Frequently asked questions
Does Medicare cover I73.9 (Peripheral vascular disease, unspecified)?
Medicare covers items and services, not diagnoses. 10 Medicare billing and coding articles list I73.9 as a covered diagnosis for 29 HCPCS Level II codes: the diagnosis can support medical necessity for those codes, but payment still depends on the LCD's coverage criteria and the medical record.
Which HCPCS codes can be billed with ICD-10 I73.9?
The Level II codes from the policies most specific to this diagnosis are G0127 (Trimming of dystrophic nails, any number, 4 articles); C8900 (Magnetic resonance angiography with contrast, abdomen, 3 articles); C8901 (Magnetic resonance angiography without contrast, abdomen, 3 articles); C8902 (Magnetic resonance angiography without contrast followed…, 3 articles); C8909 (Magnetic resonance angiography with contrast, chest…, 3 articles). Code choice depends on the item supplied; check each code's descriptor.
