Nondisp transverse fx unsp patella, 7thG

This code signifies a follow-up encounter for a patient who sustained a transverse fracture of the kneecap, where the bone fragments remain in their normal anatomical alignment. The fracture is not specified as left or right, and the healing process is progressing slower than expected, but the skin over the fracture site remains intact.

This code is appropriate for subsequent visits where a patient is being monitored for a previously diagnosed nondisplaced transverse patellar fracture that is demonstrating delayed union. This includes appointments for cast changes, physical therapy evaluations, or imaging studies to assess healing progress, specifically when the physician documents delayed healing.

• Ensure documentation explicitly states "nondisplaced transverse fracture of patella" and "delayed healing" for a closed fracture.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Do not use this code if the laterality (left or right) of the patella is documented; a more specific code would be required.
