Oth fx unsp patella, subs for opn fx type I/2 w delay heal

This code describes a follow-up visit for an open fracture of the kneecap, specifically a Type I or Type II open fracture, that is not healing as expected. The "other" designation indicates the fracture pattern is not a transverse, comminuted, or unspecified type.

Use this code when a patient presents for ongoing management of an open patellar fracture (Gustilo-Anderson Type I or II) that has not yet achieved union and is experiencing delayed healing. This applies to encounters after the initial treatment of the fracture.

• Ensure documentation specifies an open fracture type I or II and delayed healing.
• Verify this is a subsequent encounter, not the initial treatment or a sequela.
• Confirm the fracture is of the patella and not another bone in the knee.
