Excessive weight gain in pregnancy, unspecified trimester

This code signifies a diagnosis of gestational weight gain exceeding recommended guidelines, without specifying the particular trimester in which the excessive gain was identified. It indicates a maternal health concern during pregnancy related to weight management.

Use this code when documentation clearly states "excessive weight gain in pregnancy" but does not specify the trimester. This is appropriate when the provider has identified the condition but the exact timing within the pregnancy is not recorded or is unknown.

• Avoid using this code if the trimester of excessive weight gain is documented; instead, use the more specific O26.01-, O26.02-, or O26.03- codes.
• Ensure the medical record explicitly states "excessive weight gain" rather than just "weight gain," which is a normal physiological process in pregnancy.
• This code should be sequenced as a secondary diagnosis when another condition is the primary reason for the encounter, unless the excessive weight gain is the sole reason for the visit.
