ICD Code I77.1

ICD code I77.1 is a narrowing or constriction of an artery, which can restrict blood flow and lead to various complications depending on the location and severity of the stricture.

1. Evidence of narrowing or constriction in an artery confirmed by imaging studies (e.g., angiography, ultrasound, CT, or MRI).

2. Clinical symptoms attributable to reduced arterial blood flow, such as claudication, ischemic pain, or tissue hypoperfusion.

3. Absence of acute arterial occlusion or embolism.

4. Exclusion of congenital arterial malformations or aneurysms as the primary cause.

5. Documentation of chronic or acquired arterial narrowing not related to atherosclerosis or arteriosclerosis.

6. Supporting findings from physical examination, such as diminished pulses or bruits over the affected artery.

Relevant CPT codes that may be used to treat ICD code I77.1 include:

- 35475: Transluminal balloon angioplasty, percutaneous; brachiocephalic trunk or branches, each vessel

- 35476: Transluminal balloon angioplasty, percutaneous; renal or other visceral artery, each vessel

- 37220: Revascularization, endovascular, open or percutaneous, iliac artery, unilateral, initial vessel

- 37221: Revascularization, endovascular, open or percutaneous, iliac artery, unilateral, each additional vessel

- 37224: Revascularization, endovascular, femoral/popliteal artery, initial vessel

- 37225: Revascularization, endovascular, femoral/popliteal artery, with atherectomy, initial vessel

- 37226: Revascularization, endovascular, femoral/popliteal artery, with stent, initial vessel

- 37227: Revascularization, endovascular, femoral/popliteal artery, with atherectomy and stent, initial vessel

- 35371: Thromboendarterectomy, including patch graft, carotid, vertebral, subclavian, by neck incision

- 35372: Thromboendarterectomy, including patch graft, iliac, femoral, popliteal artery

These CPT codes are commonly associated with procedures to treat I77.1. Always confirm code selection based on the specific artery and procedure performed.
