Putting ICD-10 into Practice: Coding exercises and scenarios (Specialty focus: Immune Deficiencies and Disorders)

October 2, 2013

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.

Specialty focus: Immune Deficiencies and Disorders

Coding exercises

Code the following conditions according to ICD-10 coding conventions and guidelines:

  1. Postinfectious acute disseminated encephalitis and encephalomyelitis
  2. Autoimmune hemolytic anemia (drug-induced)
  3. Nezelof?s syndrome
  4. Pemphigus vulgaris
  5. Rh isoimmunization of newborn
  6. Stiff-man syndrome
  7. Hereditary hypogammaglobulinemia
  8. Immune thrombocytopenic purpura
  9. Transfusion-related hemochromatosis
  10. Congenital neutropenia
  11. Stevens-Johnson syndrome
  12. Hereditary hemochromatosis
  13. Critical illness polyneuropathy
  14. Systemic lupus erythematosus
  15. Transient neonatal neutropenia
  16. Systemic lupus erythematosus involving the lung
  17. Wiskott-Aldrich syndrome
  18. Transient neonatal thrombocytopenia
  19. Von Willebrand?s disease
  20. Benign mucous membrane pemphigoid
  21. Churg-Strauss syndrome

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.
