Bent bone of r ulna, subs for opn fx type I/2 w delay heal

This code describes a fracture of the right ulna, specifically a bent bone, that was initially an open fracture of either Type I or Type II. The patient is currently in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed open Type I or II fracture of the right ulna (bent bone) is being monitored for healing progress, and that progress is slower than anticipated. It indicates ongoing management of the fracture's delayed union.

• Ensure documentation clearly specifies "bent bone" of the ulna and not another fracture type.
• Verify the initial fracture was classified as an open Type I or II.
• Confirm the encounter is for subsequent care and that delayed healing is explicitly documented.
