Oth nondisp fx of base of 1st MC bone, r hand, 7thB

This code signifies a fracture at the base of the first metacarpal bone (thumb) in the right hand that is not displaced. It specifically indicates that the fracture is an open type, meaning the skin and soft tissue have been compromised, exposing the bone. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with an open, nondisplaced fracture at the base of their right thumb metacarpal. This would include scenarios like a crush injury or direct trauma where the bone is visible or there's a significant wound communicating with the fracture site.

• Always confirm the laterality (right hand) and the specific bone (first metacarpal base).
• Verify that the fracture is indeed "nondisplaced" and "open" as documented by the physician.
• Ensure this is the patient's initial encounter for this specific injury; subsequent care would use a different encounter character.
