Acute on chr slipped upper femoral epiphy, stable, bi hips

This code describes a condition where the growth plate (epiphysis) at the top of both femurs has slipped from its normal position, occurring gradually over time but with a recent worsening of symptoms. The "stable" designation indicates that the patient is able to bear weight on the affected hips, and "nontraumatic" confirms the absence of an acute injury as the cause.

Use this code for patients presenting with symptoms of a slipped upper femoral epiphysis (SUFE) that has been ongoing but recently exacerbated, affecting both hips, and where the patient can still ambulate. Documentation should clearly state "acute on chronic," "stable," "bilateral," and rule out a traumatic origin.

• Differentiate from acute SUFE (M93.01-) or chronic SUFE (M93.02-) which do not specify an acute exacerbation.
• Ensure documentation explicitly states "bilateral" and "stable" to support this specific code.
• Verify the nontraumatic nature; traumatic slips would be coded differently.
