Acute on chr slip upper fem epiphy, unsp stability, bi hips

This code describes a condition where the head of the femur (epiphysis) has slipped from the femoral neck, occurring acutely on a pre-existing chronic slip, affecting both hips. The stability of the slip is not specified, and it is attributed to non-traumatic causes.

Use this code when documentation clearly indicates an acute exacerbation of a chronic slipped upper femoral epiphysis (SUFE) affecting both hips, without specifying whether the slip is stable or unstable. This code is appropriate when the etiology is non-traumatic, such as growth plate weakness or endocrine factors.

• Ensure documentation specifies "acute on chronic" and "bilateral hips" for accurate code assignment.
• Do not use this code if the slip is explicitly documented as traumatic; instead, refer to the appropriate traumatic injury codes.
• If the stability (stable vs. unstable) is documented, a more specific code within the M93.0 category should be selected.
