Other fracture of first metacarpal bone, unsp hand, sequela

This code signifies a healed or healing fracture of the first metacarpal bone (thumb) that is causing ongoing issues or requires continued care. It indicates a past injury with residual effects, rather than an acute fracture. The specific nature of the fracture and the affected hand are not specified within this code.

Apply this code when documenting a patient presenting with complications or ongoing treatment related to a previously sustained first metacarpal fracture. This includes scenarios like malunion, nonunion, pain, stiffness, or functional limitations directly attributable to the old fracture. It is appropriate for follow-up visits after the initial healing phase has passed.

• Ensure documentation clearly indicates the fracture is no longer acute and is causing a sequela.
• Always code the specific sequela (e.g., malunion, nonunion, pain) as an additional diagnosis.
• Verify the laterality (left, right, or unspecified) of the hand if known, as more specific codes exist.
