Nondisp fx of neck of unsp metacarpal bone, init for clos fx

This code signifies a break in the neck of a metacarpal bone in the hand, where the bone fragments have not shifted out of their normal alignment. The specific metacarpal bone involved is not identified, and the fracture is considered closed, meaning the skin remains intact. This code is used for the initial treatment encounter for this type of injury.

Apply this code when a patient presents with a newly diagnosed, non-displaced fracture of an unspecified metacarpal neck, such as following a direct impact to the hand. This is appropriate for the initial visit where the fracture is first evaluated and treatment plans are established, assuming no open wound is present.

• Ensure documentation clearly states "nondisplaced" and "closed fracture" for accurate code assignment.
• If the specific metacarpal (e.g., second, third) is identified, a more specific code within the S62.36- category should be used.
• The "A" seventh character indicates an initial encounter for active treatment; subsequent encounters will require different seventh characters.
