Acute on chr slipped upper femoral epiphy, stable, unsp hip

This code describes a condition where a patient experiences an acute worsening of a pre-existing, long-standing slipped upper femoral epiphysis (SUFE) in an unspecified hip. The "slipped" growth plate (epiphysis) at the top of the femur has acutely displaced further, but the condition is considered stable and not caused by trauma.

Use this code when documentation clearly indicates an acute exacerbation of a chronic, non-traumatic, stable slipped upper femoral epiphysis affecting an unspecified hip. This typically involves a patient with a known history of SUFE presenting with new or significantly worsened symptoms without a new traumatic event.

• Ensure documentation specifies "acute on chronic" and "stable" to differentiate from acute or chronic-only SUFE.
• Confirm the absence of trauma; if traumatic, a different code would be appropriate.
• If the hip (left or right) is specified in the documentation, select the more specific code.
