Stress fracture, right humerus, init encntr for fracture

This code signifies a fatigue fracture of the right humerus, resulting from repetitive stress rather than acute trauma. It indicates a microfracture or hairline crack in the bone due to cumulative submaximal loading.

Apply this code for a patient presenting with a newly diagnosed stress fracture of the right humerus. Documentation should clearly state "stress fracture" and specify the right humerus as the affected bone, along with the initial phase of treatment.

• Ensure documentation explicitly states "stress fracture" to differentiate from traumatic fractures.
• Verify laterality (right humerus) is clearly documented.
• This "A" seventh character is only for the initial encounter for active treatment of the fracture. Subsequent encounters will require different seventh characters.
