Putting ICD-10 into Practice: Coding exercises and scenarios

November 1, 2013


These coding exercises and scenario are designed to help you put the new ICD-10 guidelines and conventions into practice. An answer key is provided so you can verify if your answers are correct. In addition, code narratives are included 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: Diseases of the Eye and Adnexa

Coding scenario

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

Robin and her husband are celebrating their daughter Kennedy?s 16th birthday. Kennedy is a well-mannered honor student and an avid athlete. To show their love and appreciation to their daughter, they purchased a new car for her. Kennedy began studying for her driver?s license immediately. While completing her application for the license, she came across questions on the form that asked if she had any of the following conditions: day, night, or color blindness; visual halos; double vision; glare sensitivity; or declared legally blind. Kennedy was concerned because she wears prescription glasses; fortunately, none of these conditions applied to her.
