Oth fx shaft of l ulna, 7thJ

This code signifies a fracture of the shaft of the left ulna, excluding specific types like Monteggia or Galeazzi, that is open and classified as Type IIIA, IIIB, or IIIC. The "J" seventh character indicates that the patient is in a subsequent phase of care, specifically experiencing delayed healing of this complex open fracture.

Use this code for follow-up encounters where a patient with a previously diagnosed open fracture of the left ulnar shaft (Type IIIA, IIIB, or IIIC) is presenting with evidence of delayed bone healing. This applies when the fracture has not united within the expected timeframe for this type of injury.

• Ensure documentation clearly specifies "delayed healing" for the "J" seventh character.
• Confirm the fracture is of the ulnar shaft and not the distal or proximal end.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is documented to support the specificity of this code.
