Displ spiral fx shaft of unsp tibia, 7thM

This code signifies a complex tibial shaft fracture that has not healed properly (nonunion) and is displaced, meaning the bone fragments are out of alignment. It specifically applies to open fractures classified as Type I or II, indicating a break in the skin with minimal to moderate soft tissue damage, and is being treated in a subsequent encounter. The "unspecified tibia" indicates that the laterality (left or right) of the fracture is not documented.

Use this code for patients presenting for follow-up care, cast changes, wound care, or surgical intervention related to a previously diagnosed displaced spiral fracture of the tibial shaft that was an open Type I or II fracture and has now developed nonunion. This code is appropriate when the medical record does not specify whether the fracture occurred in the left or right tibia.

• Ensure documentation clearly states "nonunion" and specifies an "open fracture type I or II" for the initial injury.
• Verify that the encounter is "subsequent" and not the initial treatment for the fracture.
• Only use "unspecified tibia" when laterality is genuinely not documented; otherwise, use a more specific code.
