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

This code signifies a right patellar fracture that has healed in an anatomically incorrect position (malunion), specifically involving a transverse break across the kneecap. The "subsequent encounter" indicates that the patient is receiving ongoing care for this previously diagnosed and treated fracture, now complicated by malunion, and the fracture itself remains closed (skin intact).

Use this code for follow-up visits where a patient is being evaluated or treated for a right patellar malunion that resulted from a transverse fracture. This applies when the original fracture was closed and the current encounter addresses the complications or management of the malunion. It is appropriate for scenarios such as assessing range of motion limitations, pain management related to the malunion, or planning for corrective surgery.

• Ensure documentation clearly states "malunion" and specifies the right patella and transverse fracture type.
• Verify that the encounter is for follow-up care of the malunion, not the initial treatment of the acute fracture.
• Confirm the fracture was initially closed; if it was open, a different code would be appropriate.
