Nondisp commnt fx r patella, 7thN

This code describes a complex, multi-fragmented fracture of the right kneecap that has not shifted out of alignment. It specifically indicates that the fracture is an open injury (where the bone breaks through the skin) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly after initial treatment.

Use this code for follow-up encounters when a patient is receiving ongoing care for a right patellar fracture that was initially an open, comminuted injury and is now complicated by nonunion. This applies to situations such as continued wound care, assessment for further surgical intervention for nonunion, or management of complications related to the unhealed fracture.

• Ensure documentation clearly specifies "nondisplaced," "comminuted," "right patella," and "open fracture type IIIA, IIIB, or IIIC" with "nonunion."
• This "N" seventh character indicates a subsequent encounter for a nonunion; do not use for initial treatment or routine healing.
• Verify the specific type of open fracture (IIIA, IIIB, or IIIC) is documented, as this impacts code selection for other fracture types.
