What ICD-10 codes would be first listed for a pregnant 30 weeks pregnant female admitted to antepartum preterm contractions following a motor vehicle accident (Pt hit a deer head-on; c/o pain where seatbelt was. 30 weeks along. Pt c/o cramping)? O60.00, R51.9, V89.2XXA, Z04.1, Z3a.30. Also, please correct me if I am wrong but I would bill this to the patient's health insurance. TIA!
