Oth fx of lower end of unsp radius, init for opn fx type I/2

This code signifies an open fracture of the distal radius, not otherwise specified, where the bone has broken through the skin or there is a wound communicating with the fracture site. This type of fracture is classified as Gustilo-Anderson Type I or II, indicating a relatively clean wound with minimal to moderate soft tissue damage. It represents the initial treatment encounter for this injury.

Use this code for a patient presenting with a newly diagnosed open fracture of the lower end of the radius, where the specific fracture pattern (e.g., Colles', Smith's) is not documented, and the open nature is classified as Type I or II. This code is appropriate for the initial hospital visit, emergency department encounter, or first physician's office visit for this injury.

• Ensure documentation clearly specifies "open fracture" and the Gustilo-Anderson classification (Type I or II).
• Do not use this code if the fracture is explicitly documented as a specific type of distal radius fracture (e.g., Colles', Smith's); use a more specific code.
• The "B" seventh character indicates an initial encounter for an open fracture. Subsequent encounters will require a different seventh character.
