Torus fx upper end of right ulna, subs for fx w malunion

This code describes a torus, or buckle, fracture affecting the upper portion of the right ulna that has healed incorrectly, resulting in a malunion. A torus fracture is an incomplete fracture where one side of the bone buckles upon itself without a complete break in the cortex. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously treated fracture.

This code is appropriate for encounters where a patient is being evaluated or treated for complications arising from a malunited torus fracture of the right proximal ulna. This includes scenarios such as pain, limited range of motion, or deformity due to the improper healing of the initial fracture. It is used after the initial treatment of the fracture has concluded.

• Ensure documentation clearly specifies "malunion" as the complication of the fracture.
• Verify the laterality (right ulna) and the specific location (upper end) are accurately documented.
• Confirm this is a subsequent encounter, not an initial treatment or sequela.
