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

This code signifies a break in the bone closest to the hand in the right thumb, where the bone fragments are not properly aligned. It specifically indicates that the skin and soft tissue overlying the fracture site have been compromised, exposing the bone to the external environment. This is the first time the patient is being treated for this specific injury.

Apply this code for a patient presenting with a newly diagnosed, open fracture of the proximal phalanx of the right thumb. This would be appropriate for initial surgical intervention, emergency department visits, or initial clinic evaluations following the injury. It is used when the fracture is documented as displaced and open.

• Ensure documentation clearly states "right thumb" and "proximal phalanx" to support this specific site.
• Confirm the fracture is explicitly documented as "displaced" and "open" to differentiate from other fracture types.
• The "B" seventh character indicates an initial encounter for an open fracture; use subsequent characters for follow-up care.
