Stress fracture, unsp humerus, subs for fx w delay heal

This code describes a stress fracture affecting an unspecified part of the humerus bone. It indicates that the patient is in a subsequent phase of care for this fracture, specifically experiencing delayed healing. This means the bone is not mending at the expected rate.

Use this code for patients presenting for follow-up care of a previously diagnosed stress fracture of the humerus where healing is progressing slower than anticipated. Documentation should clearly state "stress fracture," "humerus" (without specifying left or right), and "delayed healing" during a subsequent encounter.

• Ensure documentation specifies "stress fracture" as opposed to other types of fractures (e.g., pathological, traumatic).
• The "G" seventh character indicates subsequent encounter with delayed healing; do not confuse with "A" for initial encounter or "D" for subsequent encounter with routine healing.
• If the laterality (left or right humerus) is documented, a more specific code from the M84.32- series should be used.
