Nondisp seg fx shaft of ulna, unsp arm, 7thH

This code describes a specific type of ulna fracture where the bone is broken in multiple places along the shaft but the fragments remain in their normal alignment. It indicates that the fracture is an open fracture (meaning the skin was broken) of either Type I or II, and the patient is presenting for follow-up care due to delayed healing.

Use this code for a patient presenting for a subsequent encounter for an open, nondisplaced segmental fracture of the ulnar shaft, when the healing process is taking longer than expected. This applies to cases where the initial injury involved a break in the skin, categorized as Gustilo-Anderson Type I or II.

• Ensure documentation specifies "segmental" and "nondisplaced" for the ulna shaft fracture.
• Confirm the encounter is for "subsequent care" and that "delayed healing" is explicitly noted.
• Verify the original injury was an "open fracture type I or II" to justify the 7th character 'H'.
