Nondisp fx of r ulna styloid pro, 7thM

This code describes a fracture of the styloid process of the right ulna that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, which was initially an open fracture (skin broken) classified as Type I or II, and has now developed nonunion, meaning the bone is failing to heal.

Use this code when documenting ongoing treatment for a patient with a previously diagnosed right ulnar styloid fracture that was initially an open fracture (Type I or II) and is now complicated by nonunion. This applies to follow-up visits, cast changes, or surgical interventions aimed at promoting healing of the nonunion.

• Ensure documentation clearly specifies "right" ulna and "styloid process" to differentiate from other forearm fractures.
• The "M" seventh character signifies a subsequent encounter for an open fracture with nonunion; verify the initial injury was indeed an open fracture Type I or II.
• Pair this diagnosis code with appropriate procedure codes for any interventions performed to address the nonunion.
