Nondisp fx of first metatarsal bone, unsp foot, init

This code signifies a break in the first metatarsal bone that has not shifted from its normal anatomical position. It applies to injuries where the skin remains intact over the fracture site. This is an initial encounter code, indicating the patient is receiving active treatment for the fracture.

Use this code for patients presenting with a newly diagnosed, non-displaced closed fracture of the first metatarsal. This is appropriate for the initial visit where the fracture is identified and a treatment plan, such as casting or splinting, is initiated. It should be selected when the specific foot (left or right) is not documented.

• Ensure documentation specifies "nondisplaced" and "closed" to support this code.
• Verify the encounter is for initial treatment; subsequent care will require a different encounter character.
• If the specific foot is known, use a more specific code (e.g., S92.311A for left, S92.312A for right).
