435.2 - Subclavian steal syndrome | ICD-10-CM.
The term "subclavian steal" refers to a phenomenon of flow reversal in the vertebral artery ipsilateral to a hemodynamically significant stenosis or occlusion of the prevertebral subclavian artery [1-3].
A 2020 article lists the following common neurological symptoms of subclavian steal syndrome:hearing loss.tinnitus.blurred vision.dizziness.vertigo.loss of muscle coordination, or ataxia.fainting.
ICD-9-CM is the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States. The ICD-9 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started.
Confirmation of a steal syndrome is usually made by imaging studies. All imaging tools can be used to detect subclavian stenosis and to observe reversal of flow from the vertebral artery. Carotid duplex ultrasound(US) is the most used and usually the first diagnostic test.
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.
Subclavian steal syndrome (SSS), also known as subclavian-vertebral artery steal syndrome, is a phenomenon causing retrograde flow in an ipsilateral vertebral artery due to stenosis or occlusion of the subclavian artery, proximal to the origin of the vertebral artery.
Ischemic steal syndrome (ISS) is a complication that can occur after the construction of a vascular access for hemodialysis. It is characterized by ischemia of the hand caused by marked reduction or reversal of flow through the arterial segment distal to the arteriovenous fistula (AVF).
The diagnosis of steal is based on an accurate history and physical examination and confirmed with tests including an arteriogram, duplex Doppler ultrasound (DDU) evaluation with finger pressures and waveform analysis. Treatment of steal includes observation of developing symptoms in mild cases.
ICD9Data.com takes the current ICD-9-CM and HCPCS medical billing codes and adds 5.3+ million links between them. Combine that with a Google-powered search engine, drill-down navigation system and instant coding notes and it's easier than ever to quickly find the medical coding information you need.
A Five-Step ProcessStep 1: Search the Alphabetical Index for a diagnostic term. ... Step 2: Check the Tabular List. ... Step 3: Read the code's instructions. ... Step 4: If it is an injury or trauma, add a seventh character. ... Step 5: If glaucoma, you may need to add a seventh character.
Currently, the U.S. is the only industrialized nation still utilizing ICD-9-CM codes for morbidity data, though we have already transitioned to ICD-10 for mortality.
As of October 2015, ICD-9 codes are no longer used for medical coding. Instead, use this equivalent ICD-10-CM code, which is an approximate match to ICD-9 code 435.2:
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.

Non-Billable means the code is not sufficient justification for admission to an acute care hospital when used a principal diagnosis. Use a child code to capture more detail.
