Stress fracture, right ulna, subs for fx w delay heal

This code signifies a stress fracture of the right ulna that is currently undergoing treatment for delayed healing. A stress fracture is a small crack in the bone, often caused by repetitive stress or overuse, rather than a single traumatic event. Delayed healing indicates that the fracture is taking longer than expected to unite.

Apply this code when a patient presents for follow-up care of a previously diagnosed right ulnar stress fracture that is not healing at the anticipated rate. Documentation should clearly state "delayed healing" and specify the right ulna as the affected site. This code is appropriate for subsequent encounters after the initial treatment has begun.

• Ensure documentation specifies "stress fracture" and not a traumatic fracture, as different codes apply.
• Verify laterality (right ulna) is clearly documented; incorrect laterality is a common coding error.
• Confirm the encounter is for "subsequent" care with "delayed healing" to differentiate from initial treatment or routine healing.
