Nondisp Zone II fracture of sacrum, subs for fx w delay heal

This code signifies a sacral fracture located in Zone II (involving the sacral foramina but not extending to the sacroiliac joint), which is not displaced. The patient is in a phase of recovery where the fracture is healing slower than expected, and this encounter is specifically for ongoing management of that delayed healing.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed nondisplaced Zone II sacral fracture is experiencing delayed union. It should be used when the physician is assessing or treating the fracture's slow healing process, such as during repeat imaging, physical therapy evaluations, or medication adjustments aimed at promoting bone growth.

• Ensure documentation clearly specifies "delayed healing" for the sacral fracture.
• Verify the fracture location is indeed Zone II and that it is nondisplaced.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
