ICD-10: M87.144

Osteonecrosis, particularly as classified under ICD-10 code M87.144, refers to a specific condition characterized by the death of bone tissue due to a lack of blood supply, which can be exacerbated by various factors, including drug use. This particular code denotes osteonecrosis that affects the right finger(s) and is attributed to the effects of medication.

Clinical Description of Osteonecrosis

Definition and Pathophysiology

Osteonecrosis, also known as avascular necrosis, occurs when blood flow to a bone is disrupted, leading to the death of bone cells. This condition can result from various causes, including trauma, excessive alcohol consumption, certain medical conditions (like lupus or sickle cell disease), and the use of specific medications, particularly corticosteroids and bisphosphonates[1][6].

Symptoms

Patients with osteonecrosis may experience:
- Pain: Often the first symptom, which may start as mild and progressively worsen. Pain can be localized to the affected area, in this case, the right fingers.
- Limited Range of Motion: As the condition progresses, patients may find it difficult to move the affected fingers.
- Swelling and Tenderness: The area around the affected bone may become swollen and tender to touch.
- Joint Stiffness: This can occur, particularly if the osteonecrosis affects the joints in the fingers.

Diagnosis

Diagnosis typically involves:
- Medical History and Physical Examination: A thorough assessment of symptoms and any relevant medical history, including medication use.
- Imaging Studies: X-rays, MRI, or CT scans are crucial for visualizing the extent of bone damage and confirming the diagnosis of osteonecrosis[1][6].
