Fracture of unsp phalanx of unsp finger, init for opn fx

This code describes a broken bone in any of the finger bones (phalanges) where the specific finger or phalanx is not documented. The fracture is open, meaning the skin and soft tissue are also broken, exposing the bone. This code is used for the initial treatment of such an injury.

Apply this code when documentation confirms an open fracture of a finger phalanx, but the specific finger (e.g., index, middle) or phalanx (e.g., proximal, middle, distal) is not specified. It is appropriate for the first encounter where the patient presents for active treatment of this acute injury.

• Ensure the documentation clearly states "open fracture" to differentiate from closed fractures.
• Only use this code when the specific finger or phalanx cannot be determined from the medical record.
• Verify that this is the initial encounter for treatment of the fracture, not a subsequent visit for healing or complications.
