Gestational edema, first trimester

This code identifies the presence of edema (swelling) specifically related to pregnancy, occurring during the first trimester. It signifies fluid retention without hypertension or proteinuria, distinguishing it from pre-eclampsia.

Apply this code when documentation clearly indicates generalized or localized edema in a pregnant patient during her first trimester, and there is no evidence of gestational hypertension or pre-eclampsia. Supporting documentation would include physician notes detailing the presence of edema and the gestational age.

• Ensure the documentation specifies "edema" and not other forms of swelling.
• Verify the gestational trimester is explicitly stated as the first trimester.
• Do not use this code if gestational hypertension or proteinuria are also present; consider codes for pre-eclampsia.
