ICD10 code of Raynaud's disease and ICD9 code

Raynaud's disease is classified under ICD-10 code I73.00 (Raynaud's syndrome, unspecified) or I73.01 (Raynaud's syndrome with gangrene), while the legacy ICD-9 code is 443.0. These codes are essential for medical billing, insurance documentation, and clinical record-keeping when managing the vasospastic episodes characteristic of this condition.

What is the clinical distinction for Raynaud's disease coding?

When clinicians document Raynaud's disease, they must distinguish between primary Raynaud's (the idiopathic form) and secondary Raynaud's (Raynaud's phenomenon), which is often associated with underlying connective tissue disorders like scleroderma or lupus. While the ICD-10 code I73.00 serves as the primary identifier, your specialist may use additional codes to reflect any secondary systemic conditions contributing to the severity of your Raynaud's disease symptoms.

How does Raynaud's disease affect the body?

Raynaud's disease is characterized by exaggerated vascular responses to cold temperatures or emotional stress, leading to a temporary reduction in blood flow to the fingers and toes. Patients within the DiseaseMaps community, where 49 members share their experiences, often report the following progression during a vasospastic attack:

• Phase 1: Ischemia, where fingers turn white due to restricted blood flow.


• Phase 2: Cyanosis, where the skin turns blue as oxygen-depleted blood pools in the vessels.


• Phase 3: Hyperemia, where the return of blood flow causes the skin to turn bright red, often accompanied by throbbing or tingling.

Is Raynaud's disease considered a chronic condition?

Yes, Raynaud's disease is a chronic condition that requires consistent management. While primary Raynaud's disease is often mild and manageable through lifestyle modifications, the clinical coding remains important for monitoring potential progression or complications, such as digital ulcers. Understanding your specific ICD-10 classification helps your healthcare team track the impact of Raynaud's disease on your long-term vascular health.

Next steps

• Consult a rheumatologist or vascular specialist to confirm whether your symptoms are primary or secondary.


• Maintain a symptom diary to track the frequency and triggers of your Raynaud's disease episodes.


• Join the DiseaseMaps.org community to connect with other patients and share management strategies.


• Ask your provider to ensure your ICD-10 coding is accurate to facilitate proper insurance coverage for diagnostic testing.
