Nondisp comminuted fx unsp patella, init for opn fx type I/2

This code signifies a fracture of the kneecap that has broken into multiple pieces (comminuted) but where the bone fragments remain in their anatomical position (nondisplaced). It specifically applies when the skin over the fracture is broken, indicating an open fracture classified as Type I or Type II, and this is the first time the patient is receiving treatment for this injury.

Use this code for a patient presenting with a newly diagnosed comminuted patellar fracture that has not shifted, and there is a wound communicating with the fracture site, classified as Gustilo-Anderson Type I or II. This code is appropriate for the initial hospital visit or encounter where definitive treatment for the fracture begins.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the patella.
• Verify the open fracture type (Gustilo-Anderson I or II) is documented; otherwise, an unspecified open fracture code may be more appropriate.
• The "B" seventh character indicates an initial encounter for an open fracture, so subsequent care would require a different seventh character.
