Physeal arrest, humerus, unspecified

This code describes the premature cessation of growth in the growth plate (physis) of the humerus, the long bone of the upper arm, when the specific side (left or right) is not documented. This condition can lead to limb length discrepancies and angular deformities.

Use this code when documentation indicates a physeal arrest affecting the humerus, but the laterality is not specified. This diagnosis is typically made based on imaging studies such as X-rays, which show premature fusion or bridging of the growth plate.

• Do not use this code if the laterality (right or left humerus) is documented; instead, select the more specific code.
• Consider codes for underlying causes of physeal arrest, such as trauma or infection, if documented.
• Ensure documentation clearly states "physeal arrest" or "growth plate arrest" of the humerus.
