Oth fx of lower end left radius, init for opn fx type 3A/B/C

This code signifies a fracture of the lower end of the left radius that is not further specified as a Colles', Smith's, or Barton's fracture, and is characterized by an open wound where the bone has broken through the skin. The "C" suffix indicates that this is the initial encounter for a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC), implying significant soft tissue damage and contamination.

Use this code for a patient presenting for the first time with a newly diagnosed, unspecified fracture of the distal left radius that is openly exposed to the environment. This applies when the open fracture is classified as Gustilo-Anderson type IIIA, IIIB, or IIIC, requiring immediate surgical intervention and aggressive wound management.

• Ensure documentation clearly specifies the left radius and the "other" fracture type, ruling out Colles', Smith's, or Barton's.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is explicitly stated or clearly inferable from the physician's notes regarding the open wound severity.
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters will require different seventh characters.
