Nondisp transverse fx unsp patella, 7thH

This code describes a fracture of the kneecap that runs horizontally across the bone without any displacement of the fragments. It specifically indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or Type II severity, and the patient is now in a subsequent phase of care where the healing process is taking longer than expected.

Use this code for a patient presenting for follow-up care of a previously diagnosed open transverse patellar fracture (Type I or II) where the fracture fragments are still aligned, but the physician notes delayed union or non-union. This applies to situations where the patient is receiving ongoing treatment, such as cast changes, physical therapy, or medication adjustments, due to slow healing.

• Ensure documentation clearly specifies "nondisplaced" and "transverse" morphology of the patellar fracture.
• Verify the initial injury was an "open fracture type I or II" and that the encounter is for "delayed healing."
• Do not use for initial encounters or for closed fractures.
