Pitutiary and Adrenal Condtions 

Code 7909: Diabetes insipidus is completely different from diabetes mellitus. It is either caused by the body not producing enough antidiuretic hormone or by the kidneys not recognizing and responding properly to that hormone. Without this hormone, much higher levels of water in the body are filtered out through the urine. It causes polyuria. Polyuria is excessive or an abnormally large production or passage of urine. 

This condition is rated 30% for the first 3 months after diagnosis. At that point, if there is still polyuria that requires constant hormone medication, it is rated 10%. All other remaining symptoms are rated separately.

Gestational diabetes can occur during pregnancy, but this condition resolves after the birth and is not ratable.
