Submit one of these 10 more specific codes instead:

  • O33.0 Maternal care for disproportion due to deformity of maternal pelvic bones
  • O33.1 Maternal care for disproportion due to generally contracted pelvis
  • O33.2 Maternal care for disproportion due to inlet contraction of pelvis
  • O33.3 Maternal care for disproportion due to outlet contraction of pelvis (also a header)
  • O33.4 Maternal care for disproportion of mixed maternal and fetal origin (also a header)
  • O33.5 Maternal care for disproportion due to unusually large fetus (also a header)
  • O33.6 Maternal care for disproportion due to hydrocephalic fetus (also a header)
  • O33.7 Maternal care for disproportion due to other fetal deformities (also a header)
  • O33.8 Maternal care for disproportion of other origin
