Final answer:
Option (d), Hiatal hernias are the only hernia type with repair codes not located in the digestive system code range because they involve the stomach protruding through the diaphragm, which is anatomically separate from the digestive tract areas that include inguinal, umbilical, and femoral hernias.
Step-by-step explanation:
The only hernia repair codes that are NOT located in the digestive system range of codes are the codes for the repair of hiatal hernias. Inguinal, umbilical, and femoral hernias involve areas that are part of the digestive system anatomy, and thus their repair codes are typically found within the digestive-related range of procedural codes.
A hiatal hernia involves the stomach protruding through the diaphragm into the chest cavity, which is outside the scope of digestive system-specific coding categories.
