Unsp fracture of fourth metacarpal bone, left hand, sequela

This code indicates a fracture of the fourth metacarpal bone in the left hand where the specific type of fracture (e.g., transverse, oblique, comminuted) is not documented. The "S" seventh character signifies that this code is for a sequela, meaning it represents a late effect or complication of the original injury, not the initial acute fracture.

Use this code when documenting a long-term complication or residual condition directly resulting from a previously sustained, unspecified fracture of the left fourth metacarpal. This could include chronic pain, malunion, nonunion, or functional impairment that is a direct consequence of the old fracture. It is appropriate when the acute phase of healing has passed.

• Always ensure the "S" seventh character is used only for sequelae, not for initial encounters or subsequent encounters for routine healing.
• Verify that the medical record clearly links the current condition to a past, unspecified fracture of the left fourth metacarpal.
• Look for documentation of "due to old fracture," "residual effect of fracture," or similar phrasing to support the sequela designation.
