Unsp physeal fx upper end of r tibia, subs for fx w nonunion

This code signifies a subsequent encounter for a fracture of the growth plate at the upper end of the right tibia that has failed to heal properly (nonunion). The specific type of physeal fracture is not documented, indicating an unspecified nature. This condition can lead to growth disturbances and functional limitations in the affected limb.

Use this code when a patient presents for follow-up care of a previously diagnosed physeal fracture of the right proximal tibia that has not united. This applies to situations where the nonunion is confirmed, and the encounter is for ongoing management, evaluation of healing progress, or planning for further intervention.

• Ensure documentation clearly states "nonunion" and specifies the right tibia and "physeal fracture."
• Verify that this is a subsequent encounter, not an initial treatment for the nonunion.
• Pair with an external cause code if the initial injury mechanism is relevant and documented.
