Nondisp fx of base of third MC bone, l hand, init for opn fx

This code signifies a fracture at the base of the third metacarpal bone in the left hand. The fracture is described as nondisplaced, meaning the bone fragments are still in their normal anatomical alignment. It also specifies an "open" fracture, indicating a break in the skin that exposes the bone or allows communication with the fracture site.

This code is appropriate for the initial encounter of a patient presenting with a newly diagnosed, nondisplaced open fracture at the base of their left third metacarpal. This would typically be used in emergency department settings, urgent care, or initial orthopedic consultations following the injury.

• Ensure documentation clearly specifies "nondisplaced" and "open" for accurate code assignment.
• Verify the laterality (left hand) and the specific metacarpal (third) are correctly identified in the medical record.
• Remember the "B" seventh character indicates an initial encounter for an open fracture; subsequent encounters will require different seventh characters.
