Code Description

ICD-10 M87.35 is a billable code used to indicate a diagnosis of other secondary osteonecrosis, pelvis and femur.

Key Diagnostic Point:

M87.35 refers to a specific type of osteonecrosis that occurs in the pelvis and femur, which is characterized by the death of bone tissue due to a lack of blood supply. This condition can arise as a secondary complication from various underlying conditions such as corticosteroid use, alcohol abuse, or certain diseases like lupus or sickle cell anemia. Patients may present with pain in the hip or groin area, limited range of motion, and may experience joint dysfunction. Diagnosis typically involves imaging studies such as X-rays or MRI, which can reveal changes in bone density and structure. Treatment options may include conservative management with pain relief and physical therapy, or surgical interventions such as core decompression or joint replacement in severe cases. Understanding the etiology and management of osteonecrosis is crucial for effective treatment and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between primary and secondary osteonecrosis
  • Identifying the underlying causes contributing to the condition
  • Understanding the specific anatomical locations affected (pelvis and femur)
  • Navigating the documentation requirements for various specialties

Audit Risk Factors

  • Inadequate documentation of underlying conditions
  • Failure to specify the anatomical site of osteonecrosis
  • Misclassification of primary versus secondary osteonecrosis
  • Lack of imaging studies to support the diagnosis

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed patient history, imaging results, and treatment plans must be documented.

Common Clinical Scenarios

Patients presenting with hip pain, limited mobility, or after corticosteroid therapy.

Billing Considerations

Orthopedic surgeons must ensure that the cause of osteonecrosis is clearly documented to support the use of M87.35.

Rheumatology

Documentation Requirements

Comprehensive documentation of systemic diseases that may contribute to osteonecrosis.

Common Clinical Scenarios

Patients with autoimmune diseases or those on long-term corticosteroids.

Billing Considerations

Rheumatologists should document the relationship between the underlying condition and the development of osteonecrosis.

Coding Guidelines

Inclusion Criteria

Use M87.35 When
  • According to ICD
  • 10 guidelines, M87
  • 35 should be used when osteonecrosis is confirmed to be secondary to another condition
  • Coders must ensure that the underlying cause is documented and that the anatomical site is specified

Exclusion Criteria

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to capture secondary causes and enhancing the accuracy of patient records.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to capture secondary causes and enhancing the accuracy of patient records.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of osteonecrosis, improving the ability to capture secondary causes and enhancing the accuracy of patient records.
