Stress fracture, left ulna, subs for fx w routn heal

This code signifies a stress fracture of the left ulna that is currently undergoing routine healing. It indicates that the patient is in the recovery phase following the initial diagnosis and treatment of the stress fracture.

Apply this code when documentation specifies a stress fracture of the left ulna and the patient is seen for follow-up care during the healing process. This is appropriate for subsequent visits where the fracture is progressing as expected without complications. Documentation should explicitly state "stress fracture," "left ulna," and indicate a "subsequent encounter" with "routine healing."

• Ensure documentation clearly specifies "stress fracture" versus other types of ulnar fractures.
• Verify the laterality (left ulna) is explicitly stated in the medical record.
• Confirm the encounter is for follow-up care with routine healing; do not use for initial treatment or nonunion/malunion.
