Medically necessary for chronic symptomatic PAD when: functionally limiting claudication; inadequate response to GDMT including structured exercise; and expected quality-of-life/walking/functional benefit outweighs risks/durability of intervention.
Percutaneous revascularization for treatment of chronic limb-threatening ischemia may be considered medically necessary.
Percutaneous revascularization for treatment of acute limb ischemia may be considered medically necessary.
Percutaneous revascularization for chronic symptomatic lower extremity PAD may be medically necessary when: functionally limiting claudication; inadequate response to guideline-directed management and therapy (including structured exercise); and potential benefits outweigh risks, durability concerns, and possible need for repeat procedures.
Percutaneous revascularization in individuals with asymptomatic lower extremity PAD may be medically necessary when required for the safety, feasibility, or effectiveness of other invasive, clinically necessary, life-saving procedures (examples provided).
