Code Description

ICD-10 M87.122 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs, left humerus.

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 M87.122, the osteonecrosis is specifically attributed to drug use, which can include corticosteroids, chemotherapy agents, and other medications that may compromise blood flow to the bone. The left humerus, being one of the long bones in the upper arm, is particularly susceptible to this condition, leading to pain, limited range of motion, and potential joint dysfunction. Patients may present with symptoms such as localized pain, swelling, and tenderness in the shoulder area. Diagnosis typically involves imaging studies such as MRI or X-rays, which can reveal changes in bone density and structure. Treatment options may vary from conservative management, including pain relief and physical therapy, to surgical interventions like core decompression or joint replacement in advanced cases. Understanding the etiology and management of drug-induced osteonecrosis is crucial for effective treatment and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of specific drugs that can cause osteonecrosis.
  • Differentiation from other types of osteonecrosis.
  • Documentation must specify the affected bone and its relation to drug use.
  • Potential for co-morbid conditions that may complicate coding.

Audit Risk Factors

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

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like osteonecrosis, enabling better tracking of drug-related complications. M87.122 provides a clear framework for identifying cases of osteonecrosis due to drug use, which can improve patient management and treatment outcomes.

ICD-9 vs ICD-10
