Unspecified sprain of left wrist, subsequent encounter

This code signifies an undiagnosed or poorly defined sprain affecting the left wrist, encountered during a follow-up visit after initial treatment. It indicates that the specific ligament(s) involved in the sprain were not identified or documented at the time of the initial injury or subsequent assessment. The injury is to the soft tissues supporting the left wrist joint.

This code is appropriate for use when a patient presents for ongoing care, such as physical therapy, follow-up appointments, or medication refills, for a left wrist sprain where the precise ligamentous involvement remains unspecified. It should be used when the initial encounter code for the acute injury was also unspecified, or when further diagnostic clarity has not yet been achieved.

• Ensure documentation clearly states "left wrist" and "sprain" without further specificity regarding the injured ligament(s).
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• Avoid using this code if a more specific diagnosis (e.g., sprain of a specific carpal ligament) is documented.
