Colles' fracture of left radius, subs for clos fx w malunion

This code signifies a Colles' fracture, a specific type of distal radius fracture, affecting the left arm. The fracture has previously been treated and is now in a healing phase, but with an unsatisfactory alignment of the bone fragments (malunion), requiring ongoing management.

Apply this code when a patient presents for follow-up care of a previously treated left Colles' fracture that has healed or is healing in a misaligned position. This includes scenarios where the malunion is being monitored, or further intervention (e.g., corrective osteotomy planning) is being considered.

• Ensure documentation clearly specifies "left" radius and "Colles' fracture" type.
• Verify the encounter is for a "subsequent" visit and that "malunion" is explicitly documented.
• Do not use for initial treatment or for nonunion; specific codes exist for those scenarios.
