Nondisp transverse fx r patella, subs for clos fx w malunion

This code describes a right patellar fracture that extends horizontally across the bone, where the bone fragments remain in their anatomical position. The patient is in a later stage of care, and the fracture is healing improperly, resulting in a malunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced transverse fracture of the right patella, and imaging or clinical assessment confirms that the fracture has healed in a misaligned or deformed position. This would be used for subsequent encounters after the initial treatment, where the focus is on managing the malunion.

• Ensure documentation clearly specifies "right" patella and "nondisplaced transverse" fracture type.
• Confirm the encounter is for subsequent care and explicitly states "malunion" of a closed fracture.
• Do not use for initial treatment or for nonunion, which is a different complication.
