Osteonecrosis due to drugs, ankle, foot and toes
ICD-10 M87.17 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs, ankle, foot and toes.
Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. In the case of M87.17, the osteonecrosis is specifically attributed to the use of certain medications, which can disrupt blood flow to the bones. This condition commonly affects the ankle, foot, and toes, leading to pain, limited mobility, and potential joint dysfunction. The pathophysiology involves the death of osteocytes and bone marrow cells, resulting in structural collapse of the bone. Risk factors include long-term use of corticosteroids, excessive alcohol consumption, and certain chemotherapy agents. Clinically, patients may present with localized pain, swelling, and difficulty bearing weight. Diagnosis typically involves imaging studies such as MRI or X-rays, which can reveal changes in bone density and structure. Treatment options may include medication adjustments, physical therapy, or surgical interventions such as core decompression or joint replacement, depending on the severity of the condition.
Detailed history of medication use, imaging results, and clinical findings.
Patients presenting with joint pain after corticosteroid therapy.
Ensure clear documentation linking drug use to osteonecrosis.
Comprehensive medication history, including dosage and duration.
Patients with autoimmune disorders on long-term immunosuppressants.
Monitor for signs of osteonecrosis in patients receiving high-dose corticosteroids.
Used for pain management in patients with osteonecrosis.
Document the joint involved and the reason for the procedure.
Orthopedic specialists should ensure clear linkage between the procedure and the diagnosis.
Common medications include corticosteroids, bisphosphonates, and certain chemotherapy agents. It is essential to document any relevant medication history when coding.
