0.000What This Code Means
Death of bone tissue in body locations other than those specifically listed in the osteonecrosis classification. This can affect various bones and lead to pain and functional impairment.
Coding Tips
- •Use this code for osteonecrosis in sites not otherwise specified (e.g., pelvis, ribs, sternum)
- •Document the specific anatomical site affected to support medical necessity and justify treatment decisions
Clinical Significance
Other site osteonecrosis represents avascular bone death occurring in anatomical locations not specifically categorized elsewhere, indicating the systemic nature of the underlying condition. This broad category requires careful documentation of the specific site and underlying etiology.
Documentation Requirements
- ✓Specific anatomical site documentation (not covered by other M87 codes)
- ✓Imaging evidence confirming osteonecrosis at the specified location
- ✓Clear exclusion of traumatic, infectious, or radiation-induced causes
- ✓Assessment of functional impact related to affected site
- ✓Pain evaluation and quality of life measures
- ✓Comprehensive evaluation for underlying systemic conditions
- ✓Multidisciplinary care plan appropriate to anatomical location
- ✓Disease progression monitoring and treatment response
Commonly Confused Codes
M87.38 — Drug-induced osteonecrosis requires specific causative agentM87.18 — Post-traumatic osteonecrosis needs documented trauma historyM87.08 — Idiopathic osteonecrosis has no identifiable underlying causeM89.8X9 — Other specified disorders of bone are not necessarily necroticM90.58 — Osteonecrosis in diseases classified elsewhere needs primary condition
