Unsp fracture of unsp toe(s), subs for fx w nonunion

This code indicates a patient is presenting for follow-up care of a toe fracture where the specific toe involved is not documented, and the fracture has failed to heal properly. The nonunion signifies that the bone fragments have not united after a sufficient healing period, requiring further intervention or management.

Use this code for subsequent encounters when a patient with an unspecified toe fracture is diagnosed with nonunion. This applies when the initial fracture site (e.g., phalanx, metatarsal head) is not specified in the medical record. It is appropriate for ongoing management, evaluation of nonunion, or planning for surgical correction.

• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter.
• Avoid using this code if a more specific toe (e.g., great toe, lesser toe) or specific phalanx is documented.
• Pair this diagnosis with appropriate procedure codes for nonunion treatment, if applicable.
