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

This code describes a Colles' fracture, which is a specific type of distal radius fracture characterized by dorsal displacement of the distal fragment, affecting the right arm. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" signifies that the fracture has healed in an anatomically incorrect or deformed position.

Use this code when a patient presents for ongoing treatment, evaluation, or management of a previously sustained Colles' fracture of the right radius that has healed improperly. This would include scenarios where a patient is being assessed for pain, functional limitations, or considering corrective surgery due to the malunion.

• Ensure documentation clearly specifies "right" radius and confirms the presence of malunion.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Distinguish between malunion (healed incorrectly) and nonunion (failed to heal).
