Acute slipped upper femoral epiphy, unsp stability, r hip

This code signifies a sudden displacement of the femoral head from the femoral neck through the growth plate in the right hip, occurring without a specific traumatic event. This condition, often seen in adolescents, is characterized by a weakened growth plate leading to a "slipping" of the epiphysis.

Apply this code when documentation specifies an acute, nontraumatic slipped upper femoral epiphysis affecting the right hip. This diagnosis is typically supported by imaging studies (e.g., X-rays) showing epiphyseal displacement and clinical findings of hip pain and altered gait.

• Ensure documentation clearly states "acute" and "nontraumatic" to differentiate from chronic or traumatic variants.
• Verify laterality (right hip) is explicitly documented; separate codes exist for left and bilateral involvement.
• Do not confuse with avascular necrosis of the femoral head (M87.-) or other hip disorders unless explicitly documented as co-occurring.
