Excessive weight gain in pregnancy, second trimester

This code signifies a diagnosis of excessive or abnormal weight gain occurring specifically during the second trimester of pregnancy. It indicates a maternal health concern where the patient's weight increase exceeds recommended guidelines for gestational weight gain.

Apply this code when documentation clearly states "excessive weight gain" or "abnormal weight gain" and specifies the second trimester. Supporting documentation would include physician notes detailing weight measurements and the gestational age at which the excessive gain was noted.

• Ensure the documentation explicitly states "second trimester" for accurate code assignment.
• Do not confuse with general maternal weight gain codes if the excess is not explicitly documented or if the trimester is not specified.
• Consider co-morbid conditions such as gestational diabetes or pre-eclampsia, which may be associated with excessive weight gain, and code them separately if documented.
