Acute slipped upper femoral epiphy, unsp stability, bi hips

This code describes a condition where the growth plate (epiphysis) at the top of both femurs slips backward and downward from the femoral neck. This slippage is acute, meaning it occurred suddenly, and is not attributed to trauma. It represents a bilateral presentation of this hip disorder.

Apply this code when documentation clearly indicates an acute, non-traumatic slipped upper femoral epiphysis affecting both hips. This diagnosis is typically made in adolescents presenting with sudden onset hip or knee pain and a characteristic limp. The "unspecified stability" component is used when the degree of stability (stable vs. unstable) is not documented.

• Ensure documentation specifies "acute" and "bilateral" involvement.
• Distinguish from chronic or acute-on-chronic presentations, which have different codes.
• If stability is documented (stable or unstable), use the more specific code from the M93.06- subcategory.
