Unsp physeal fx upper end of humerus, unsp arm, init

This code signifies a fracture occurring through the growth plate (physis) at the top of the humerus, the long bone of the upper arm. The specific side (left or right) of the injury is not documented, and the fracture is closed, meaning the skin remains intact. This code is used for the initial treatment of such an injury.

Use this code when documentation indicates a physeal fracture of the proximal humerus but does not specify laterality (e.g., "physeal fracture of upper humerus"). It is appropriate for the initial encounter for treatment of a closed fracture where no further detail regarding the fracture type or displacement is provided.

• Ensure the encounter is the initial treatment for the fracture; subsequent encounters will require different seventh characters.
• Avoid this code if laterality (left or right arm) is documented; more specific codes are available.
• Only use when the fracture is explicitly described as "unspecified" regarding laterality and the type of physeal fracture is not further detailed.
