Code Description

ICD-10 M87.145 is a billable code used to indicate a diagnosis of osteonecrosis due to drugs, left finger(s).

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 M87.145, this condition is specifically attributed to drug use, which can include corticosteroids, bisphosphonates, or other medications that may compromise blood flow to the bone. The left finger(s) indicates that the necrosis is localized to the bones of the fingers on the left hand. Patients may present with pain, swelling, and limited range of motion in the affected fingers. The condition can lead to joint dysfunction and may require surgical intervention, such as joint replacement or bone grafting, if not managed appropriately. The diagnosis of osteonecrosis is typically confirmed through imaging studies, such as MRI or X-rays, which can reveal changes in bone density and structure. Understanding the etiology, particularly the role of pharmacological agents, is crucial for effective management and prevention of further complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of drug-related osteonecrosis and its specific coding guidelines.
  • Differentiation from other types of osteonecrosis and related conditions.
  • Documentation must specify the affected anatomical site accurately.
  • Potential for misclassification with other bone disorders.

Audit Risk Factors

  • Inadequate documentation linking drug use to osteonecrosis.
  • Failure to specify the affected finger(s) accurately.
  • Misuse of related codes that do not specify drug-related causes.
  • Lack of imaging studies to support the diagnosis.

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed patient history, imaging results, and treatment plans.

Common Clinical Scenarios

Patients presenting with pain in the fingers after corticosteroid therapy.

Billing Considerations

Orthopedic surgeons must document the specific drugs used and their duration.

Rheumatology

Documentation Requirements

Comprehensive medication history and assessment of joint function.

Common Clinical Scenarios

Patients with autoimmune disorders receiving long-term steroid therapy.

Billing Considerations

Rheumatologists should monitor for signs of osteonecrosis in patients on high-dose steroids.

Coding Guidelines

Inclusion Criteria

Use M87.145 When
  • According to ICD
  • 10 guidelines, M87
  • 145 should be used when osteonecrosis is specifically due to drug use, and the affected site is the left finger(s)
  • Coders must ensure that documentation supports the diagnosis and that the specific drug causing the condition is noted

Exclusion Criteria
