Code Description

ICD-10 M87.136 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs of unspecified ulna.

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 M87.136, the osteonecrosis is specifically attributed to drug use, which can include corticosteroids, alcohol, and other medications that may compromise blood flow to the bone. The ulna, one of the two long bones in the forearm, is affected in this instance, leading to pain, limited mobility, and potential joint dysfunction. Patients may present with symptoms such as localized pain, swelling, and decreased range of motion in the affected arm. Diagnosis typically involves imaging studies like MRI or X-rays, which can reveal changes in bone density and structure. Treatment options may include medication, physical therapy, or surgical interventions such as core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying causes, including the specific drugs involved, is crucial for effective management and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Identification of the specific drug causing osteonecrosis.
  • Differentiation from other forms of osteonecrosis.
  • Documentation of the ulna as the affected site.
  • Need for comprehensive patient history regarding medication use.

Audit Risk Factors

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