Low weight gain in pregnancy, second trimester

This code signifies inadequate maternal weight gain during the second trimester of pregnancy. It indicates that the pregnant individual is not gaining weight at a rate considered healthy or sufficient to support fetal growth and maternal well-being during this specific gestational period.

This code is appropriate when a pregnant patient's weight gain falls below established clinical guidelines for the second trimester, as documented by the obstetrician or other healthcare provider. Documentation should include serial weight measurements and a clear statement from the provider indicating "low weight gain" or "inadequate weight gain" specifically in the second trimester.

• Ensure the documentation explicitly states "second trimester" to support the specificity of this code.
• Do not confuse this with codes for maternal malnutrition or other specific nutritional deficiencies, unless those conditions are also documented.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the pregnancy itself or another complication.
