Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. The ICD-10 code M87.179 specifically refers to osteonecrosis caused by drugs, affecting unspecified toe(s). Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Osteonecrosis (ICD-10 Code M87.179)

Definition

Osteonecrosis due to drugs is a form of bone necrosis that occurs when the blood supply to the bone is compromised, often as a side effect of certain medications. This condition can lead to the collapse of the bone structure, resulting in pain, limited mobility, and potential joint dysfunction.

Etiology

The primary cause of osteonecrosis in this context is the use of specific pharmacological agents. Common drugs associated with this condition include corticosteroids, bisphosphonates, and certain chemotherapy agents. These medications can interfere with blood flow to the bones, particularly in areas with a limited blood supply, such as the toes.

Symptoms

Patients with osteonecrosis of the toe(s) may experience:
- Pain: Often described as a deep, aching pain that worsens with weight-bearing activities.
- Swelling: Localized swelling around the affected toe(s).
