Nondisp osteochon fx unsp patella, 7thF

This code describes a nondisplaced osteochondral fracture of the patella, where the bone and cartilage are involved but not significantly separated. It specifically indicates a subsequent encounter for an open fracture that was initially classified as type IIIA, IIIB, or IIIC, and is now healing routinely.

This code is appropriate when a patient is receiving follow-up care for a previously treated open patellar osteochondral fracture. The initial injury must have been a severe open fracture (Gustilo-Anderson types IIIA, IIIB, or IIIC), and the current encounter signifies a period of expected, uncomplicated healing.

• Ensure the documentation specifies a "subsequent encounter" and "routine healing."
• Verify the initial open fracture was classified as type IIIA, IIIB, or IIIC.
• Confirm the fracture is nondisplaced and involves both bone and cartilage of the patella.
