Cont preg aft spon abort of one fts or more, first tri, oth

This code signifies a multifetal pregnancy where one or more fetuses have been spontaneously aborted during the first trimester, but at least one other fetus remains viable and the pregnancy is ongoing. It indicates a partial loss within a multiple gestation.

Apply this code when documentation clearly states a spontaneous abortion of one or more fetuses in a multiple gestation during the first trimester, with the remaining fetus(es) continuing to develop. This would typically be supported by ultrasound reports confirming fetal demise of one sac and viability of another, along with clinical notes detailing the spontaneous abortion event.

• Ensure the documentation specifies "spontaneous" abortion and not an induced termination or elective reduction.
• Verify the trimester of the fetal demise; this code is specific to the first trimester.
• Do not confuse with codes for complete spontaneous abortion (O03.-) or other complications of multiple gestation without fetal loss.
