Our neonatologist is asked to consult with pregnant mom who is hospitalized with issues causing the expectation of premature delivery. Neonatologist counsels Mom on risks of preterm delivery to baby and what to expect for baby once she delivers (respiratory management concerns, possible NICU stay, etc.). Neonatologist does not treat mom's condition(s). What ICD-10-CM code should the doctor use to report this service for reimbursement? Is there a diagnosis code for this type of consultation or would we use the mom's diagnosis that caused the threat of preterm delivery?
