ICD10 code of Thoracic Outlet Syndrome and ICD9 code

Thoracic Outlet Syndrome (TOS) is primarily coded as G54.0 (Brachial plexus disorders) in ICD-10-CM, while it was historically classified under 353.0 (Brachial plexus lesions) in ICD-9-CM. Because Thoracic Outlet Syndrome encompasses various compression types, clinicians may also utilize specific codes related to vascular or neurogenic involvement if the primary code is insufficient for clinical documentation.

What is the clinical classification of Thoracic Outlet Syndrome?

Thoracic Outlet Syndrome occurs when blood vessels or nerves in the space between your collarbone and first rib (the thoracic outlet) are compressed. Clinical diagnosis of Thoracic Outlet Syndrome is categorized into three main types: neurogenic (nTOS), venous (vTOS), and arterial (aTOS). Because these presentations vary, medical coding for Thoracic Outlet Syndrome often relies on the underlying anatomical structure being affected, such as the brachial plexus or the subclavian vessels.

How is Thoracic Outlet Syndrome diagnosed?

Diagnosing Thoracic Outlet Syndrome is complex because symptoms often overlap with other musculoskeletal conditions. Our 60 community members at DiseaseMaps.org frequently report that the diagnostic journey involves a combination of the following clinical evaluations:

• Physical Provocation Tests: Such as the Adson’s maneuver or Roos test to elicit symptoms.


• Electromyography (EMG) and Nerve Conduction Studies: Used to confirm neurogenic Thoracic Outlet Syndrome.


• Imaging: Duplex ultrasound, CT angiography, or MRI to visualize vascular compression.


• Clinical History: Assessing for repetitive overhead work or trauma that may have triggered the onset of Thoracic Outlet Syndrome.

Is Thoracic Outlet Syndrome a permanent condition?

For many, Thoracic Outlet Syndrome is a manageable condition, but it requires a multidisciplinary approach. While some patients find relief through physical therapy and postural correction, others may require surgical intervention to decompress the thoracic outlet. The prognosis for Thoracic Outlet Syndrome depends heavily on early intervention and the specific type of compression involved.
