Nondisp longitud fx l patella, subs for clos fx w routn heal

This code describes a left kneecap fracture that runs lengthwise (longitudinal) and has not shifted out of its normal anatomical position. The patient is in a subsequent phase of care, meaning they are receiving follow-up treatment for this fracture, which is healing as expected without complications.

Use this code for follow-up encounters where a patient is being monitored for a previously diagnosed nondisplaced longitudinal fracture of the left patella. This applies when the fracture is closed (skin intact) and is progressing through routine healing, such as during cast changes, physical therapy evaluations, or routine clinic visits after initial treatment.

• Ensure documentation specifies "nondisplaced" and "longitudinal" for the patella fracture.
• The 7th character 'D' indicates a subsequent encounter for a fracture undergoing routine healing.
• Do not use for initial treatment, malunion, nonunion, or delayed healing.
