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

This code signifies a break in the outermost bone of the left thumb, specifically one that has not shifted from its normal position. The fracture is classified as "open," meaning there is a wound that communicates with the fracture site, exposing the bone to the outside environment. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the first encounter for a patient presenting with an open, nondisplaced fracture of the distal phalanx of the left thumb. This includes situations where the patient is initially evaluated, diagnosed, and receives definitive treatment for this specific injury. It would be used for procedures like wound debridement, fracture reduction, and initial stabilization.

• Ensure documentation clearly specifies "nondisplaced" and "open" for the distal phalanx of the left thumb.
• Verify this is the patient's initial encounter for this specific fracture; subsequent care would use a different encounter character.
• Always code the open wound type (e.g., Type I, II, III) if documented, using an additional external cause code if applicable.
