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

This code describes an initial encounter for an open fracture of the third metacarpal bone in the right hand. An open fracture indicates that the skin and soft tissue overlying the fracture site have been compromised, exposing the bone to the external environment. The "unspecified" nature means the specific type of fracture (e.g., transverse, oblique, comminuted) is not documented.

Use this code when a patient presents for the first time with a right hand injury where the third metacarpal bone is broken, and the fracture is visibly open to the environment. This is appropriate when the physician's documentation confirms an open fracture but does not specify the fracture type.

• Ensure documentation clearly states "open fracture" and specifies the "right hand" and "third metacarpal."
• Verify this is the patient's initial encounter for this specific injury; subsequent encounters would use different seventh characters.
• If the fracture type (e.g., transverse, oblique) is documented, a more specific code should be selected.
