Unspecified fracture of shaft of unspecified tibia, sequela

This code signifies a long-term complication or late effect stemming from a fracture of the main part of the shin bone, where the specific location on the shaft and the side of the body are not documented. It indicates that the initial injury has healed, but the patient is still experiencing residual problems directly related to that past fracture.

This code is appropriate for encounters addressing sequelae such as malunion, nonunion, chronic pain, deformity, or functional limitations that are a direct result of a previously sustained and healed tibial shaft fracture. It should be used when the original fracture site and laterality were not specified in the initial injury documentation, or if that information is unavailable.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., M84.48 for malunion).
• Ensure documentation clearly links the current condition to a past tibial shaft fracture.
• Avoid using this code for acute or active fractures; it is exclusively for late effects.
