Fracture of unspecified carpal bone, left wrist, sequela

This code signifies a long-term complication or late effect resulting from a fracture of an unspecified carpal bone in the left wrist. It indicates that the initial injury has healed, but the patient is still experiencing residual symptoms or conditions directly attributable to that past fracture.

This code is appropriate when a patient presents with ongoing issues such as chronic pain, limited range of motion, nonunion, malunion, or other persistent sequelae directly linked to a previously sustained, but now healed, fracture of an unspecified carpal bone in the left wrist. It should be used for encounters addressing these late effects, not the initial acute injury.

• Always sequence this "S" code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.532 for chronic pain in left wrist).
• Ensure documentation clearly links the current condition to a past fracture of an unspecified carpal bone in the left wrist.
• Avoid using this code for acute or active fractures; those require codes from the initial encounter or subsequent encounter categories.
