Nondisp transverse fx unsp patella, 7thP

This code describes a patellar fracture that runs horizontally across the kneecap, has not shifted out of alignment, and is currently in a healing phase where the bone has healed but in an imperfect position. This malunion indicates that the bone fragments have joined, but the anatomical alignment is not ideal, potentially leading to functional issues.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced transverse patellar fracture that has healed with a documented malunion. This applies when the fracture is closed (skin intact) and the focus of the encounter is on managing the consequences or ongoing care related to this imperfect healing.

• Ensure documentation explicitly states "malunion" for a previously nondisplaced transverse patellar fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture was closed; open fractures have different coding pathways.
