Nondisp fx of prox phalanx of r idx fngr, init for opn fx

This code signifies a break in the bone of the first segment of the right index finger, closest to the hand, where the bone fragments have not separated. It specifically indicates that the skin was broken at the time of injury, exposing the bone, and this is the initial treatment encounter for the fracture.

Apply this code for a patient presenting for the first time with an open fracture of the proximal phalanx of the right index finger that is documented as nondisplaced. This would include injuries resulting from trauma where the skin integrity is compromised over the fracture site.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for the proximal phalanx of the right index finger.
• The "B" seventh character indicates an initial encounter for the fracture, regardless of whether surgical or conservative treatment is rendered.
• Verify laterality (right index finger) and the specific phalanx (proximal) are explicitly stated in the medical record.
