Answer :
Final answer:
The correct ICD-10-CM code for the principal diagnosis is I70.219, and the correct ICD-10-PCS code for the principal procedure is 04LA4DZ, reflecting treatment for arteriosclerosis with angioplasty and atherectomy in the left popliteal artery. The correct answer is A) ICD-10-CM: I70.219; ICD-10-PCS: 04LA4DZ.
Explanation:
The student asked for the ICD-10-CM code for the principal diagnosis and the ICD-10-PCS code for the principal procedure related to left lower extremity intermittent claudication with high grade left popliteal artery stenosis, treated with Diamondback atherectomy and low-pressure balloon angioplasty. The correct answer is A) ICD-10-CM: I70.219; ICD-10-PCS: 04LA4DZ. This coding reflects a diagnosis of arteriosclerosis obliterans (atherosclerosis) of the extremities without gangrene, specifically in the unspecified leg, and the procedural codes match the techniques used in the angioplasty and atherectomy for non-coronary arterial disease.
Angioplasty is a procedure aimed at mechanically widening an occlusion within an artery using a balloon catheter. This method is complemented by atherectomy, a process that removes plaque from an artery, hence optimizing blood flow. Such interventions are critical in managing and treating vascular disease, particularly to alleviate symptoms like intermittent claudication resulting from obstructed arterial blood flow, as experienced in this case.
