ICD-10 Code I73.00 – Raynaud’s syndrome without gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I73.00 – Raynaud’s syndrome without gangrene
What it is
I73.00 identifies Raynaud’s syndrome without gangrene, a vasospastic disorder that reduces blood flow to the digits. You use it when the condition is documented and there is no tissue death.
Clinical signs
Typical findings include episodic color changes, numbness, tingling, or pain in fingers or toes triggered by cold or stress. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Raynaud’s syndrome and specifically notes no gangrene. It may apply to primary or secondary Raynaud’s if the record supports the diagnosis and the absence of tissue necrosis. Check documentation if the chart only says vasospasm or cold sensitivity.
Do not use for
Do not use I73.00 if gangrene is present; another code is required. Also avoid it when Raynaud’s is only suspected or when the documentation supports a different peripheral vascular disorder.
Coding tip
Confirm the note states Raynaud’s syndrome and explicitly rules out gangrene before assigning I73.00.
