Other fracture of shaft of left humerus, sequela

This code signifies a long-term complication or residual effect stemming from a previous fracture of the shaft of the left humerus, excluding specific types like spiral, oblique, transverse, or comminuted. It indicates that the patient is still experiencing issues directly attributable to an old injury to the main body of their left upper arm bone.

Apply this code when documenting a patient presenting with ongoing pain, limited range of motion, nonunion, malunion, or other persistent problems in the left humerus shaft, and the original fracture has healed or is no longer in the acute phase. This is appropriate for follow-up encounters addressing the chronic consequences of the initial injury.

• Always use this seventh character 'S' for sequela when the patient is being treated for a complication or residual effect of a past fracture.
• Do not use this code for initial encounters or subsequent encounters for active fracture treatment; those require different seventh characters.
• Consider co-reporting with codes for the specific sequela (e.g., M84.422A for malunion of left humerus) if applicable and supported by documentation.
