What ICD-10 codes are used for Raynaud's Disease?

Raynaud’s Disease, also known as Raynaud’s syndrome or phenomenon, is a condition characterised by episodic vasospasm of the arteries, typically in the fingers and toes, leading to colour changes, pain, and sometimes tissue damage. The ICD-10-CM provides distinct codes to capture the presence or absence of gangrene in patients with Raynaud’s.

I73.00: Raynaud’s syndrome without gangrene:
This code is used for cases where patients experience typical Raynaud’s symptoms—such as cold-induced colour changes, numbness, or tingling—without tissue necrosis. It includes both primary and secondary Raynaud’s if no gangrene is present.
I73.01: Raynaud’s syndrome with gangrene: This code is applied when Raynaud’s episodes result in gangrene, indicating more severe or prolonged ischemia. It often reflects underlying conditions such as systemic sclerosis or other connective tissue disorders that impair vascular integrity.

When coding Raynaud’s syndrome, be sure to also include any underlying disease codes (e.g., for systemic sclerosis or lupus) to reflect the full clinical picture. Accurate coding ensures appropriate treatment planning, monitoring, and reimbursement.

Are Raynaud's Disease ICD codes billable?

Yes, Raynaud’s Disease ICD-10 codes are billable when they are fully specified. These codes are recognised by payers for clinical documentation, claims submission, and reimbursement.

Clinical information

Raynaud’s Disease is an idiopathic vascular disorder characterized by episodic vasospasm of the small blood vessels, typically in the fingers and toes. These episodes often occur in response to cold temperatures or emotional stress and result in a triphasic colour change—white (ischemia), blue (deoxygenation), and red (reperfusion).
The condition reflects abnormal reactivity within the circulatory system, where transient narrowing of the arterioles reduces blood flow to the affected areas.
In its primary form, Raynaud’s is considered a benign, standalone condition. However, bilateral Raynaud phenomenon can also be a secondary manifestation of systemic illnesses such as diabetes mellitus, systemic sclerosis, or lupus. In these cases, the vasospastic episodes may signal underlying structural damage to the blood vessels or systemic peripheral vascular diseases. When gangrene is present, it typically indicates prolonged or severe ischemia with tissue necrosis, often seen in more advanced systemic disease.
Although Raynaud’s primarily affects the extremities, it shares pathophysiological features with other peripheral vascular diseases, including those affecting larger vessels such as the cerebral artery. In both cases, impaired vascular regulation can lead to reduced perfusion, though the clinical consequences differ significantly depending on the vascular territory involved.

Commonly asked questions

The ICD-10 code for Raynaud’s disease is I73.00 if there is no gangrene, and I73.01 if gangrene is present. These codes fall under diseases of the circulatory system and are billable for clinical use.

I73.9 refers to Peripheral vascular disease, unspecified. It is used when there is a documented vascular disorder that affects circulation outside of the heart and brain but lacks specific classification.

Raynaud’s disease is a condition in which small blood vessels in the fingers and toes constrict excessively in response to cold or stress, leading to colour changes, numbness, or pain. It is an idiopathic vascular disorder and may occur on its own (primary) or as part of other systemic conditions (secondary).
