Crushing injury of unspecified thumb, initial encounter

This diagnosis code signifies a severe compressive force applied to the thumb, resulting in damage to its tissues, without specifying which thumb (right or left). It indicates the initial treatment or evaluation for this specific injury.

Apply this code when a patient presents with a thumb injury caused by a crushing mechanism, such as being caught in a door, struck by a heavy object, or compressed by machinery, and the documentation does not specify laterality. This code is appropriate for the first encounter for this injury.

• Ensure documentation clearly states a "crushing injury" and does not specify right or left thumb.
• Verify that this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
• If laterality (right or left) is documented, a more specific code should be chosen.
