The coding exercises and scenario in this section are designed to help you put the new ICD-10 guidelines and conventions into practice. An answer key is provided below so you can verify if your answers are correct. In addition, code narratives are included on the next page to describe each ICD-10 code used in the exercises and scenario. If needed, use the ICD-10 Spotlight: Know the codes booklet for assistance with these exercises.

17. Wiskott-Aldrich syndrome
18. Transient neonatal thrombocytopenia
19. Von Willebrand?s disease

Coding scenario

Code the following scenario according to ICD-10 coding conventions and guidelines: Jill gave birth to her daughter Angela at 38 weeks gestation. Although Angela was not premature, she was admitted to the Neonatal Intensive Care Unit (NICU) for ABO incompatibility, meaning Jill and Angela?s blood type did not match. In addition, Angela was diagnosed with hemolytic disease due to ABO isoimmunization.
