Ac on chr slip upper fem epiphy, unsp stability, unsp hip

This code describes a condition where a previously existing slipped upper femoral epiphysis (SUFE), also known as a slipped capital femoral epiphysis (SCFE), acutely worsens. It signifies a sudden increase in symptoms or displacement of the femoral head relative to the femoral neck, occurring in a non-traumatic context, affecting an unspecified hip, and without documentation specifying the stability of the slip.

Use this code when documentation clearly indicates an acute exacerbation or progression of a pre-existing, non-traumatic slipped upper femoral epiphysis. This applies when the specific hip (left or right) is not documented, and the stability of the slip (stable or unstable) is also not specified. Supporting documentation would include physician notes detailing acute worsening of hip pain, limp, or functional limitation in a patient with a known or newly diagnosed chronic SUFE.

• Ensure documentation specifies "acute on chronic" and "nontraumatic" to differentiate from acute-only or traumatic slips.
• Avoid using this code if the specific hip (left or right) is documented; instead, use the more specific M93.071 or M93.072.
• If the stability (stable vs. unstable) is documented, choose a more specific code from the M93.07- subcategory.
