Colles' fracture of unsp radius, subs for clos fx w nonunion

This code signifies a Colles' fracture, which is a specific type of distal radius fracture where the broken piece of the radius bone tilts upward. In this particular instance, the fracture is not healing properly (nonunion) and the patient is in a subsequent phase of care for a closed fracture. The specific radius (left or right) is not documented.

Use this code when a patient presents for follow-up care, such as cast changes, physical therapy, or re-evaluation, for a previously diagnosed Colles' fracture of an unspecified radius that has failed to unite. This applies to situations where the fracture was initially closed and is now experiencing delayed or absent bone healing.

• Ensure documentation clearly states "Colles' fracture" and "nonunion" for accurate code assignment.
• Verify that the encounter is "subsequent" and not initial or sequela care.
• If the laterality (left or right radius) is documented, a more specific code should be used.
