In my daughter's 5th month of pregnancy, she was admitted to the hospital for 2 days due to dehydration and fever. She received 4 bags of IV fluids and was treated with higher than usual doses of Tylenol for her resistant fever. Her insurance denied the claim because the hospital used a primary code of "Other Maternal Services." They are refusing to change the code, which they say is correct. They state that she was admitted because she was pregnant; obviously, she was admitted due to dehydration and fever. I was taught that this type of code should never be used as a primary code. How can I help her?
