Nondisp transverse fx shaft of r ulna, 7thN

This code describes a specific type of ulna fracture: a nondisplaced transverse break in the shaft of the right ulna. It indicates that the patient is in a subsequent encounter for an initial open fracture, specifically one classified as type IIIA, IIIB, or IIIC, and that the fracture has not healed as expected (nonunion).

Use this code for follow-up visits where a patient is being managed for a previously sustained open right ulna shaft fracture (type IIIA, IIIB, or IIIC) that is now exhibiting nonunion. This applies when the fracture was initially nondisplaced and transverse. This code is appropriate when the provider is assessing the nonunion, planning further treatment, or monitoring the condition.

• Ensure documentation clearly specifies "subsequent encounter" and "nonunion" for an open fracture.
• Verify the laterality (right ulna) and the specific fracture type (nondisplaced transverse shaft fracture).
• Confirm the original open fracture was classified as type IIIA, IIIB, or IIIC; this detail is crucial for accurate coding.
