Unsp fracture of left patella, subs for clos fx w delay heal

This code signifies a fracture of the left kneecap where the specific type of fracture (e.g., transverse, comminuted) is not documented. The patient is in a subsequent phase of care, meaning the initial treatment has occurred, and the fracture is closed (skin intact) but is not healing at the expected rate.

This code is appropriate for follow-up encounters for patients with a left patellar fracture that was initially treated conservatively or surgically, and the physician notes indicate delayed union or non-union without specifying the fracture type. It applies when the fracture site remains closed.

• Ensure documentation clearly states "left patella" and "unspecified fracture."
• Verify the encounter is for subsequent care and that "delayed healing" is explicitly documented.
• Confirm the fracture is closed; open fractures would require a different seventh character.
