Unsp fracture of left forearm, subs for clos fx w delay heal

This code signifies an unspecified fracture affecting the left forearm, meaning the specific bone (radius or ulna) or type of fracture is not documented. The "subsequent encounter" indicates the patient is receiving follow-up care for this injury, and "delayed healing" specifies that the fracture is not progressing to union at the expected rate.

Apply this code when a patient presents for ongoing management of a left forearm fracture where the exact bone or fracture type was not initially specified, and the physician notes that the healing process is slower than anticipated. This is appropriate for follow-up appointments, cast changes, or physical therapy sessions related to the delayed healing of such an injury.

• Ensure documentation clearly states "left forearm" and indicates delayed healing for a closed fracture.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• If the specific bone (radius or ulna) or fracture type is later identified, a more specific code should be used.
