Unsp fracture of first metacarpal bone, unsp hand, sequela

This code indicates a long-term complication or late effect stemming from a fracture of the first metacarpal bone (thumb bone) in an unspecified hand, where the specific type of fracture was not documented. It signifies that the initial injury has healed, but residual issues related to that fracture are now being addressed.

Use this code when documenting conditions such as chronic pain, stiffness, deformity, nonunion, or malunion of the first metacarpal, occurring after the initial fracture has healed. This applies when the original fracture details (e.g., displaced, nondisplaced) are unknown or not specified in the current encounter.

• Only use the "S" seventh character for sequelae (late effects) of a healed fracture.
• Ensure documentation clearly links the current condition to a previously sustained first metacarpal fracture.
• Avoid using this code for acute or subacute fractures; those require initial or subsequent encounter characters.
