Official Coding Guidelines

COVID-19 in pregnancy sequencing (O98.5-, U07.1)

s. COVID-19 infection in pregnancy, childbirth, and the puerperium During pregnancy, childbirth or the puerperium, when COVID-19 is the reason for admission/encounter, code O98.5-, Other viral diseases complicating pregnancy, childbirth and the puerperium, should be sequenced as the principal/first-listed diagnosis, and code U07.1, COVID-19, and the appropriate codes for associated manifestation(s) should be assigned as additional diagnoses. Codes from Chapter 15 always take sequencing priority. If the reason for admission/encounter is unrelated to COVID-19 but the patient has been diagnosed with COVID-19 during the admission/encounter, the appropriate code for the reason for admission/encounter should be sequenced as the principal/first-listed diagnosis, and codes O98.5- and U07.1, as well as the appropriate codes for associated COVID-19 manifestations, should be assigned as additional diagnoses.
