Nondisp fx of distal phalanx of unsp thumb, init for opn fx

This code signifies a fracture of the furthest bone in the thumb, specifically the distal phalanx, which has not been displaced from its normal anatomical position. It indicates that the skin and soft tissues overlying the fracture site are also compromised, creating an open wound. This is an initial encounter for treatment of this injury.

Apply this code when documenting the initial treatment for a patient presenting with a non-displaced open fracture of the distal phalanx of an unspecified thumb. This includes scenarios where the fracture is clearly visible through a skin laceration or puncture wound. It is appropriate for the first visit where definitive treatment, such as wound care, reduction, or immobilization, is initiated.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" to support this code.
• Verify laterality (left/right thumb) is not specified in the documentation; if it is, a more specific code should be used.
• Confirm this is the "initial encounter" for treatment; subsequent care would use a different encounter character.
