Gestatnl diabetes in preg, ctrl by oral hypoglycemic drugs

This code signifies gestational diabetes that develops during pregnancy and is effectively managed through the use of oral medications to control blood glucose levels. The patient's diabetes is considered stable and well-regulated with this treatment modality.

Apply this code when documentation clearly indicates a diagnosis of gestational diabetes and specifies that the patient's blood sugar is controlled solely by oral hypoglycemic agents. This typically applies to ongoing prenatal care encounters where the patient is stable on oral medication.

• Ensure documentation explicitly states "controlled by oral hypoglycemic drugs" and not insulin or diet alone.
• Always sequence this code as a secondary diagnosis following the appropriate code for the pregnancy (e.g., O09.-).
• Do not use this code if the gestational diabetes is uncontrolled or requires insulin therapy.
