Stenosis of peripheral vascular stent, subsequent encounter

This code signifies a narrowing or obstruction within a previously placed stent in a peripheral blood vessel, occurring during a follow-up visit after the initial treatment of the stenosis. This stenosis can impede blood flow to the extremities or other peripheral organs.

Apply this code when a patient presents for ongoing management or evaluation of a known stenosis within a peripheral vascular stent. This includes situations where the patient is receiving further diagnostic workup, medication adjustments, or preparing for an intervention related to the stent narrowing.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care.
• Ensure documentation clearly specifies the peripheral location of the stent and the presence of stenosis.
• Distinguish from initial encounters for stent complications or encounters for other types of stent issues.
