ICD-10-CMNondisplaced fracture of medial malleolus of unspecified tibia, initial encounter for open fracture type I or II
This code signifies a break in the inner ankle bone (medial malleolus) of an unknown tibia, where the bone fragments have not shifted out of alignment. It specifically applies when the fracture is an open fracture, meaning the skin is broken, and is classified as Type I or Type II according to the Gustilo-Anderson classification. This is the initial encounter for treatment of this specific injury.
Use this code for a patient presenting for the first time with a nondisplaced open fracture of the medial malleolus, where the specific tibia (left or right) is not documented. This is appropriate when the open fracture is described as a small puncture wound (Type I) or a moderate laceration with minimal soft tissue damage (Type II).
