Nondisplaced Rolando's fracture, left hand, init for clos fx

This code signifies a stable, non-displaced fracture of the base of the thumb metacarpal (Rolando's fracture) in the left hand. It indicates that the bone fragments are in good alignment and the injury is being treated for the first time without surgical intervention.

Apply this code for patients presenting with an acute, closed Rolando's fracture of the left hand where imaging confirms no displacement. This is appropriate for initial treatment encounters involving conservative management, such as splinting or casting.

• Ensure documentation specifies "nondisplaced" and "left hand" to support this specific code.
• Verify that the encounter is the "initial encounter" for the fracture; subsequent care would use a different seventh character.
• Confirm the fracture is "closed" (skin intact) as open fractures have distinct coding.
