Code Description

ICD-10 M87.13 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs of radius, ulna and carpus.

Key Diagnostic Point:

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 M87.13, this specific type of osteonecrosis is induced by the use of certain medications, which can compromise blood flow to the bones of the radius, ulna, and carpus. Commonly implicated drugs include corticosteroids and bisphosphonates, which are often used to treat conditions such as rheumatoid arthritis, lupus, and osteoporosis. The clinical presentation may include pain, swelling, and limited range of motion in the affected wrist or forearm. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure. If left untreated, osteonecrosis can lead to joint collapse and significant orthopedic complications, necessitating surgical interventions such as joint replacement or bone grafting. Early recognition and management are crucial to prevent irreversible damage and maintain function.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of drugs that can cause osteonecrosis, requiring thorough patient medication history.
  • Differentiation from other types of osteonecrosis not related to drug use.
  • Need for precise documentation of the drug responsible for the condition.
  • Potential for overlapping diagnoses with osteomyelitis or other bone infections.

Audit Risk Factors

  • Inadequate documentation of the drug causing osteonecrosis.
  • Failure to specify the affected bones accurately.
  • Misclassification of osteonecrosis as osteomyelitis.
  • Lack of imaging studies to support the diagnosis.
