Nondisp longitud fx r patella, subs for clos fx w delay heal

This code describes a fracture of the right kneecap that runs lengthwise (longitudinal) and has not shifted out of alignment (nondisplaced). The patient is in a later stage of care for this injury, specifically experiencing delayed healing of the closed fracture.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced longitudinal right patellar fracture is being managed for slow or incomplete bone healing. This would include clinic visits for cast changes, physical therapy evaluations, or imaging to assess healing progress when the fracture is not healing at the expected rate.

• Ensure documentation clearly states "nondisplaced," "longitudinal," and "right patella."
• Verify the encounter is for "delayed healing" and not routine follow-up or initial treatment.
• Confirm the fracture is "closed" (skin intact) to differentiate from open fractures.
