Colles' fx l rad, subs for opn fx type 3A/B/C w delay heal

This code describes a specific type of distal radius fracture, known as a Colles' fracture, affecting the left arm. It indicates that the fracture is open (meaning the skin was broken) and classified as Type IIIA, IIIB, or IIIC, and that the patient is currently experiencing delayed healing of this injury.

This code is appropriate for use when a patient presents for follow-up care of a previously diagnosed open Colles' fracture of the left radius, and the physician documents that the fracture is not healing at the expected rate. This would typically be used after the initial treatment phase, during ongoing management of the fracture.

• Ensure documentation clearly specifies "delayed healing" for this specific open Colles' fracture.
• Verify the laterality (left radius) and the open fracture type (IIIA, IIIB, or IIIC) are explicitly stated.
• This code is for a subsequent encounter, so it should not be used for the initial treatment of the fracture.
