I was advised by a Medicaid HMO payer in Texas that when coding an obstetrics claim the admitting DX should be the reason for admission and the primary DX should be the outcome. According to the ICD-10-CM coding handbook, outcome of delivery is assigned as an additional diagnosis, not the primary DX. The condition that prompted the admission should be sequenced as the primary DX, not the outcome of delivery code. Does any one have experience in coding for obstetric/delivery claims? Any info is appreciated.
