Displ bicondylar fx unsp tibia, subs for clos fx w nonunion

This code describes a situation where a patient has a bicondylar fracture of the tibia (a break involving both condyles at the top of the shin bone) that was initially displaced, and is now being treated for a nonunion. Nonunion means the fracture has failed to heal after a reasonable period of time, and this particular encounter involves a closed fracture (skin intact).

Use this code for follow-up encounters when a patient with a previously diagnosed displaced bicondylar tibial fracture, which was closed, is presenting for management of a confirmed nonunion. This typically involves ongoing treatment, evaluation, or planning for further intervention due to the lack of healing.

• Always sequence this code after the primary reason for the encounter, if applicable.
• Ensure documentation clearly states "nonunion" and specifies the fracture as "bicondylar" and "displaced" for accurate code assignment.
• Verify laterality (left, right) if specified in the medical record; "unspecified" is used when not documented.
