Unsp fx shaft of left tibia, subs for clos fx w routn heal

This code indicates a follow-up encounter for a fracture of the main part (shaft) of the left tibia, where the specific type of fracture is not documented. The fracture is closed, meaning the skin is intact, and it is progressing through a normal healing process.

This code is appropriate for subsequent visits when a patient is receiving routine care for a previously diagnosed, unspecified closed shaft fracture of the left tibia. It signifies that the fracture is healing as expected without complications.

• Ensure documentation specifies "left tibia shaft" and "unspecified fracture type" for the initial injury.
• Confirm the encounter is for routine follow-up of a closed fracture, not an open one or one with delayed/nonunion.
• The 7th character "D" is crucial, indicating a subsequent encounter with routine healing.
