Disp fx of proximal phalanx of unsp thumb, init for opn fx

This code signifies an acute, displaced fracture of the proximal phalanx of the thumb, where the skin and soft tissues are compromised, exposing the fracture site. It indicates the initial phase of treatment for such an injury, requiring medical attention for stabilization and management.

Apply this code for patients presenting with a newly diagnosed, open, displaced fracture of the thumb's proximal phalanx. This is appropriate for the initial visit where the injury is first evaluated and definitive treatment plans are established, such as surgical intervention or initial wound care.

• Ensure documentation clearly specifies "displaced" and "open fracture" for accurate code assignment.
• Verify laterality (left/right) is unspecified in the documentation to match this code's specificity.
• Confirm this is the "initial encounter" for treatment of this specific fracture. Subsequent care would require a different encounter character.
