I73.00
ICD-10-CMThis code identifies Raynaud's phenomenon, a vasospastic disorder characterized by episodic digital ischemia, without the presence of tissue necrosis. It involves temporary narrowing of blood vessels, typically in the fingers and toes, in response to cold or stress, leading to color changes and discomfort.
Apply this code when documentation clearly indicates a diagnosis of Raynaud's syndrome and explicitly states the absence of gangrene or tissue loss. This is appropriate for primary Raynaud's (idiopathic) or secondary Raynaud's where gangrene has not developed. Supporting documentation would include physician notes detailing symptoms like pallor, cyanosis, and rubor, and ruling out gangrenous changes.
