Papyraceous fetus, second trimester, other fetus

This code signifies the presence of a papyraceous fetus, a mummified twin or multiple gestation fetus that has been compressed against the uterine wall by a growing viable twin. This specific code applies when the diagnosis is made during the second trimester of pregnancy and refers to any fetus other than the one designated as the primary or index fetus.

Use this code when documentation confirms the diagnosis of a papyraceous fetus in a multiple gestation pregnancy during the second trimester. This typically occurs after the demise of one fetus, followed by its dehydration and flattening due to pressure from the co-existing viable fetus(es). Documentation should clearly specify the gestational age at diagnosis and identify which fetus is affected if there are more than two.

• Ensure the documentation specifies "second trimester" for accurate code assignment.
• Distinguish this from other fetal problems in multiple gestations; this code is specific to papyraceous transformation.
• Sequence this code after the primary obstetric code indicating the multiple gestation.
