Personal history of gestational diabetes

This code indicates that a patient has a past medical history of gestational diabetes mellitus (GDM). It signifies that the patient experienced GDM in a previous pregnancy, but is not currently pregnant or, if pregnant, is not currently experiencing GDM. This history can be a risk factor for future health complications.

This code is used when documenting a patient's past medical history, particularly during routine check-ups, pre-conception counseling, or for patients presenting with other conditions where a history of GDM is relevant to their risk assessment or management. It is also appropriate for patients who have delivered and are no longer pregnant, but had GDM in their most recent pregnancy.

• Do not use this code if the patient is currently pregnant and has gestational diabetes; refer to the O24.4- series instead.
• This code is typically used as a secondary diagnosis to provide additional information about a patient's health history.
• Ensure documentation clearly states "history of" or "previous" gestational diabetes to support the use of this code.
