Nondisp fx of base of fifth MC bone, left hand, sequela

This code signifies a healed or residual condition resulting from a fracture at the base of the fifth metacarpal bone in the left hand, which was initially nondisplaced. It indicates that the acute phase of the injury has passed, and the patient is now experiencing a long-term effect or complication related to the previous fracture. This could include ongoing pain, stiffness, deformity, or functional limitations.

Use this code when documenting a patient encounter for a follow-up visit where the primary reason for the encounter is a sequela (e.g., chronic pain, nonunion, malunion, or functional impairment) directly attributable to a previously sustained, nondisplaced fracture of the base of the left fifth metacarpal. This code is appropriate for conditions that are a late effect of the original injury, occurring after the initial healing period.

• Always assign an additional code to specify the nature of the sequela (e.g., M25.542 for chronic pain in the left hand).
• Ensure documentation clearly links the current condition to the previous fracture as a late effect.
• Do not use this code for initial treatment or active healing phases of the fracture; those require acute fracture codes.
