Pain in left foot. M79.672 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2021 edition of ICD-10-CM M79.672 became effective on October 1, 2020. This is the American ICD-10-CM version of M79.672 - other international versions of ICD-10 M79.672 may differ.

What is left iliac stenosis? Left common iliac vein stenosis frequently occurs where the vein crosses beneath the right common iliac artery. Chronic, repetitive compression at this site causes fibrosis of the vein, with synechiae and spurs that result in stenosis or even occlusion of the lumen.
Occlusion and stenosis of left carotid artery The 2022 edition of ICD-10-CM I65. 22 became effective on October 1, 2021. This is the American ICD-10-CM version of I65.
I77. 1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I77. 1 became effective on October 1, 2021.
In subclavian stenosis, the artery is simply narrowed, leading to decreased blood flow beyond the area of blockage. When the subclavian blockage is severe, or if the artery is completely blocked, a condition called 'subclavian steal' can occur (Figure 4).

Schematic of the proximal aorta and its branches. The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta. The right subclavian artery arises from the brachiocephalic artery and its branches. (Right subclavian is at upper left, and left subclavian is at upper right.)
The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck. The right subclavian artery derives from the brachiocephalic trunk, while the left subclavian artery originates directly from the aortic arch.
The subclavian arteries provide blood flow to the upper extremities. On the left, the subclavian artery originates directly from the aorta distal to the left common carotid artery.
The most common cause of subclavian artery stenosis is atherosclerosis but other causes include congenital abnormalities such as arteria lusoria (aberrant subclavian artery) or right sided aortic arch that can cause compression of the right subclavian artery leading to congenital subclavian steal syndrome,,.
Subclavian Steal Syndrome is a blockage of the subclavian artery which sits under the collarbone. It delivers blood to the arm and brain. The blockage causes the blood to flow in reverse. The arm "steals" blood flow from the blood which was intended for the posterior (back side) of the brain.
A meticulous examination of segmental pulses and pressures, as well as judicious use of duplex ultrasonography, magnetic resonance angiography, computed tomography angiography, or conventional angiography can confirm the presence of subclavian stenosis.
Duplex ultrasound with color flow imaging is the noninvasive modality of choice in the evaluation of subclavian artery disease. Dampened or monophasic waveforms, turbulent color flow imaging, and increased velocities in the region of stenosis are characteristic findings of obstruction.
If you have subclavian artery disease, the symptoms you experience depend largely on the artery involved and the degree of blockage. Symptoms may reflect a lack of blood flow to the area being supplied, such as: Arm or hand pain with activity (claudication) Numbness (paresthesia)
