Fatigue fx vertebra, thor region, subs for fx w delay heal

This code signifies a stress fracture of a thoracic vertebra that is not healing as expected after initial treatment. It indicates the patient is in an active phase of treatment for the fracture, but the healing process is prolonged or complicated.

Apply this code for follow-up encounters where a patient is receiving ongoing care for a fatigue fracture of the thoracic spine that has not yet reached full union. Documentation should clearly state "delayed healing" or similar terminology, along with the specific vertebral region.

• Ensure documentation specifies "fatigue fracture" and "thoracic region" to differentiate from other fracture types or locations.
• The "G" seventh character indicates delayed healing; do not use for routine follow-up or malunion/nonunion.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter.
