Other fracture of first metacarpal bone, left hand, sequela

This code indicates a long-term complication or late effect stemming from a previous fracture of the first metacarpal bone in the left hand. This could include chronic pain, malunion, nonunion, deformity, or restricted range of motion directly attributable to the healed or unhealed fracture. It signifies that the initial injury has resolved, but its lasting consequences are still present and require ongoing management.

Apply this code when documenting a patient presenting with a current condition that is a direct result of a past fracture of the first metacarpal bone on the left side. This is appropriate for follow-up visits addressing chronic issues like persistent pain, functional limitations, or anatomical changes that developed after the initial fracture treatment. It should be used when the acute phase of the fracture has passed, and the sequela is the primary reason for the encounter.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.542 for chronic pain in left hand).
• Ensure documentation clearly links the current condition to the previous left first metacarpal fracture.
• Verify that the "S" seventh character is appropriate, indicating a sequela, rather than an initial encounter (A), subsequent encounter (D), or other healing phases.
