Other superficial injuries of unspecified thumb, init encntr

This code signifies a superficial injury to the thumb, such as a bruise, abrasion, or minor contusion, where the specific thumb (left or right) is not documented. It indicates that the injury does not involve deeper tissues like muscle, tendon, or bone. This is the initial encounter for this specific injury.

Apply this code when documentation clearly states a superficial injury to the thumb (e.g., "thumb abrasion," "contusion of thumb") without specifying laterality. It is appropriate for the first visit where this injury is assessed and treated. Do not use if the injury involves an open wound or deeper structures.

• Ensure the documentation explicitly states "unspecified thumb" or lacks laterality for the thumb injury.
• Verify the injury is superficial; if an open wound is present, a different code from the S61 category would be more appropriate.
• Confirm this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
