Answer 1

The correct principal diagnosis code for Gabrielle's gestational diabetes mellitus, managed with a special diet, is O24.410.

Step-by-step explanation:

The correct principal diagnosis code for Gabrielle, who is 15-weeks pregnant and diagnosed with diabetes mellitus, and will be controlling it with a special diet, is O24.410 Gestational diabetes mellitus, in pregnancy, diet controlled.

Gestational diabetes mellitus (GDM) is a condition that develops during pregnancy and can be managed with diet. It is different from pre-existing diabetes mellitus, such as type 1 or type 2 diabetes. GDM occurs when the body is not able to produce enough insulin to compensate for the increased demands of pregnancy.

The code O24.410 specifically identifies GDM that is being managed through a special diet.
