Unsp fx fifth metacarpal bone, right hand, init for opn fx

This code signifies an unspecified fracture of the fifth metacarpal bone in the right hand. It indicates the initial encounter for treatment of an open fracture, meaning the skin was broken at the time of injury, exposing the bone.

Apply this code when documenting the initial diagnosis and treatment of a right fifth metacarpal fracture where the fracture is open and the specific type of fracture (e.g., transverse, oblique) is not yet determined or documented. This is appropriate for the first visit where the injury is assessed and initial care is provided.

• Ensure documentation clearly states "right hand" and "fifth metacarpal" to support laterality and bone specificity.
• Confirm the fracture is explicitly documented as "open" and this is the "initial encounter" for treatment.
• If a more specific fracture type is later identified, a more precise code will be used for subsequent encounters.
