Decision Criteria
clinical Criteria
- MRI shows necrotic lesion without trauma or drug history
Applicable To
- Idiopathic avascular necrosis of right femoral head
Clinical Validation Requirements
- MRI confirmation of necrotic lesion without trauma or drug history
Code-Specific Risks
- Ensure idiopathic nature is documented; exclude trauma or drug causes.
Coding Notes
- Document idiopathic nature clearly to avoid misclassification.

Use when osteonecrosis is confirmed to be drug-induced.
Applicable To
- Steroid-induced osteonecrosis of right femoral head
Excludes
- Idiopathic osteonecrosis (M87.05-)
- Post-traumatic osteonecrosis (M87.25-)
Clinical Validation Requirements
- Documentation of drug regimen causing osteonecrosis
Coding Notes
Link drug use explicitly to osteonecrosis.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Osteonecrosis of the Hip to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M87.051.
Impact
Clinical: Inadequate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure radiologist includes stage in imaging report., Train staff on importance of staging documentation.
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation explicitly links OA to AVN before coding both.
Impact
Risk of audits due to insufficient documentation of osteonecrosis etiology.
Mitigation Strategy
Ensure comprehensive documentation of the cause of osteonecrosis.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
