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

This code describes a condition where the growth plate (epiphysis) at the top of the left femur has gradually slipped, but has recently worsened (acute on chronic). The "stable" designation indicates that the patient is able to bear weight on the affected hip, and it is not due to a traumatic injury. This condition typically affects adolescents during periods of rapid growth.

Use this code for a patient presenting with a left hip slipped upper femoral epiphysis (SUFE) that has a history of gradual onset but is currently experiencing an acute exacerbation of symptoms. Documentation should clearly state "acute on chronic," "stable," and specify the left hip. This code is appropriate when the physician explicitly rules out a traumatic cause.

• Ensure documentation specifies "acute on chronic" and "stable" to differentiate from acute, chronic, or unstable forms.
• Verify the laterality (left hip) is clearly documented.
• Do not use this code if the slip is due to trauma; consider codes from the S79 category for traumatic epiphyseal separations.
