Nondisp fx of proximal phalanx of unspecified thumb, sequela

This code signifies a healed or residual condition resulting from a fracture of the proximal phalanx of an unspecified thumb. The original fracture was nondisplaced, meaning the bone fragments remained in their normal anatomical alignment. The "sequela" indicates that the patient is now experiencing a late effect or complication directly attributable to this past injury.

Apply this code when documenting a patient presenting with ongoing symptoms, limitations, or complications (e.g., chronic pain, stiffness, deformity, nonunion, malunion, nerve damage) that are a direct consequence of a previously sustained, nondisplaced fracture of the proximal phalanx of an unspecified thumb. This code is used after the initial healing phase of the fracture has passed.

• Always sequence this sequela code after the code for the specific late effect or complication being treated.
• Ensure documentation clearly links the current condition to the past nondisplaced proximal phalanx fracture of the thumb.
• Verify that the laterality of the thumb (left or right) was not specified in the original injury documentation if using this "unspecified" code.
