Papyraceous fetus, first trimester, fetus 2

This code signifies the presence of a papyraceous fetus, also known as fetus compressus, in a twin or higher-order multiple gestation pregnancy during the first trimester. A papyraceous fetus is a mummified, flattened, and desiccated fetal demise that occurs when one fetus in a multiple gestation pregnancy dies and is retained in utero, often compressed by the growth of the surviving fetus(es). This specific code indicates that it is the second fetus affected.

Use this code when documentation clearly identifies a papyraceous fetus in a multiple gestation pregnancy, specifically noting its occurrence in the first trimester and identifying it as the second fetus. This typically arises in scenarios where ultrasound imaging confirms the demise and compression of one twin, while the other continues to develop. Documentation should specify the trimester and the affected fetus number.

• Ensure documentation specifies "fetus 2" to accurately assign this code; otherwise, an unspecified fetus code or a code for fetus 1 may be more appropriate.
• Verify the trimester of diagnosis; codes for second and third trimesters exist and are distinct.
• Always sequence this code as a secondary diagnosis, with the primary diagnosis reflecting the reason for the encounter (e.g., routine prenatal care, complications of multiple gestation).
