Unsp fracture of right patella, subs for clos fx w malunion

This code describes a situation where a patient has experienced a fracture of their right kneecap, and the initial healing process resulted in malunion, meaning the bone fragments did not align correctly. This specific code is used when the patient is receiving follow-up care for this closed fracture with malunion.

This code is appropriate for documenting subsequent visits where a patient is being managed for a previously sustained, unspecified closed right patellar fracture that has healed incorrectly. This could include appointments for assessing the malunion, discussing surgical correction, or managing ongoing symptoms related to the improper healing.

• Ensure documentation clearly states "malunion" and specifies the right patella.
• Verify the encounter is for follow-up care of the malunion, not the initial fracture treatment.
• Pair with an external cause code if the original injury mechanism is relevant to the current encounter.
