Nondisp fx of neck of first metacarpal bone, left hand, init

This code signifies a break in the neck of the first metacarpal bone (thumb) in the left hand, where the bone fragments have not shifted out of their normal alignment. It indicates that the fracture is new and the patient is receiving initial treatment for this specific injury.

This code is appropriate for documenting a newly diagnosed, stable fracture of the left thumb metacarpal neck, confirmed by imaging (e.g., X-ray) to be nondisplaced. It should be used when the patient presents for their first visit related to this specific fracture, such as for initial evaluation, casting, or splinting.

• Ensure imaging reports explicitly state "nondisplaced" and specify the "neck of the first metacarpal" on the "left hand."
• Verify the encounter is the initial treatment for this fracture; subsequent encounters will require a different seventh character.
• Confirm the fracture is closed; open fractures would necessitate a different code.
