Clinical Description of ICD-10 Code M87.046

ICD-10 Code: M87.046
Condition: Idiopathic Aseptic Necrosis of Unspecified Finger(s)

Overview

Idiopathic aseptic necrosis, also known as osteonecrosis, refers to the death of bone tissue due to a lack of blood supply. The term "idiopathic" indicates that the exact cause of the condition is unknown. The specific code M87.046 is used to classify cases where this condition affects the unspecified finger(s) of the hand.

Pathophysiology

In idiopathic aseptic necrosis, the blood supply to the bone is disrupted, leading to bone cell death. This can result from various factors, including trauma, corticosteroid use, excessive alcohol consumption, or certain medical conditions, although in idiopathic cases, no specific cause can be identified. The lack of blood flow leads to the collapse of the bone structure, which can cause pain and functional impairment in the affected area.

Clinical Presentation

Patients with idiopathic aseptic necrosis of the fingers may present with:
