I.C.16.a.5)
Birth process or community acquired conditions
If a newborn has a condition that may be either due to the birth process or community acquired and the documentation does not indicate which it is, the default is due to the birth process and the code from Chapter 16 should be used. If the condition is community-acquired, a code from Chapter 16 should not be assigned. For COVID-19 infection in a newborn, see guideline I.C.16.h.
