Unspecified physeal fx phalanx of unspecified toe, 7thK

This code signifies a growth plate fracture in an unknown phalanx of an unspecified toe that has failed to heal properly. The patient is in a subsequent phase of care, indicating that initial treatment has been rendered and the fracture has not united as expected.

This code is appropriate for documenting ongoing management of a toe growth plate fracture where nonunion is confirmed or suspected. It is used when the specific phalanx (proximal, middle, distal) and the specific toe (great, second, etc.) are not documented. This code is also used when the patient is returning for follow-up care related to the nonunion, such as for further imaging, surgical planning, or conservative management adjustments.

• Ensure documentation clearly states "nonunion" and that the encounter is for subsequent care.
• Avoid using this code if the specific toe or phalanx is known; instead, use a more specific code from the S99.2- series.
• Pair with an external cause code (V00-Y99) if the cause of the fracture is known and relevant to the encounter.
