Would you suggest coding:
O47.* False Labor
O62.9 Abnormality of forces of labor, unspecified (Contraction, Uterus, Abnormal)
O60.0* Preterm Labor w/o delivery
O26.89* Other specified pregnancy related conditionsZ34.* Supervision of Normal Pregnancy
If no other dx, contractions NOS >37 weeks or greater, we assign threatened labor O47.1. If less than 37 weeks (no other dx like PTL), we assign O47.0. We do not assign preterm labor unless it is specifically written. If we see cervical changes, then we query.In ICD-9, the Index "pregnancy, complicated by, onset of contractions" directed coders to threatened labor.
