Unsp fx upr end r tibia, 7thN

This code describes a situation where a patient has an unhealed fracture of the upper part of their right shin bone, which was initially an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC). The "subsequent encounter" indicates that the patient is receiving ongoing treatment for this nonunion.

This code is used when a patient is seen for follow-up care, surgical intervention, or management of an unhealed open fracture of the proximal right tibia. This specifically applies when the initial injury was a severe open fracture and the bone has failed to unite.

• Ensure documentation clearly states "nonunion" and specifies the right tibia.
• Verify the original injury was an open fracture type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter for ongoing treatment, not the initial injury or routine healing.
