Code Description

ICD-10 M87.112 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs, left shoulder.

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 M87.112, the osteonecrosis is specifically attributed to the use of certain medications, which can disrupt blood flow to the bone. This condition often affects the femoral head but can also occur in other joints, including the shoulder. The left shoulder is particularly susceptible to osteonecrosis due to its anatomical structure and the vascular supply to the humeral head. Patients may present with pain, limited range of motion, and functional impairment. Diagnosis typically involves imaging studies such as X-rays or MRI to assess the extent of bone damage. Treatment options may include conservative management, such as physical therapy and pain relief, or surgical interventions like core decompression or joint replacement, depending on the severity of the condition. Understanding the underlying causes, including drug-induced factors, is crucial for effective management and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of drug-induced conditions and their effects on bone health.
  • Differentiation from other types of osteonecrosis and related conditions.
  • Documentation must specify the drug responsible for the osteonecrosis.
  • Potential for co-morbid conditions that may complicate coding.

Audit Risk Factors

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

Specialty Focus

Orthopedics

Documentation Requirements

Detailed history of medication use, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with shoulder pain and a history of corticosteroid use.

Billing Considerations

Ensure that the documentation clearly links the drug use to the osteonecrosis diagnosis.

Rheumatology

Documentation Requirements

Comprehensive medication history, including duration and dosage of drugs that may cause osteonecrosis.

Common Clinical Scenarios

Patients with autoimmune disorders on long-term immunosuppressive therapy.

Billing Considerations

Consideration of other comorbidities that may affect bone health.

Coding Guidelines

Inclusion Criteria

Use M87.112 When
  • According to ICD
  • 10 guidelines, M87
  • 112 should be used when osteonecrosis is specifically due to drug use, and the left shoulder is affected
  • Coders must ensure that the documentation supports the diagnosis and includes the specific drug responsible for the condition

Exclusion Criteria

Do NOT use M87.112 When
  • Exclusion criteria include other causes of osteonecrosis not related to drug use

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, including the identification of drug-induced cases. This specificity improves data accuracy and enhances the ability to track treatment outcomes and complications related to drug use.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, including the identification of drug-induced cases. This specificity improves data accuracy and enhances the ability to track treatment outcomes and complications related to drug use.
