Other sprain of left thumb, subsequent encounter

This code indicates a sprain of the left thumb, not otherwise specified as a ligament tear, that is currently under active treatment or healing. It signifies that the initial injury has already been assessed and this encounter is for follow-up care, such as physical therapy, re-evaluation, or monitoring recovery.

Apply this code for patients presenting for subsequent visits related to a left thumb sprain. This includes encounters for ongoing rehabilitation, medication management for pain and inflammation, or assessment of healing progress after the initial diagnosis. It is appropriate when the patient is no longer in the acute phase of injury.

• Ensure the documentation clearly states "left thumb" and "sprain" for accurate assignment.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial injury assessment or for sequelae (late effects) of the sprain.
