Putting ICD-10 into Practice: Coding exercises and scenarios (Exercise/Scenario #1)

December 28, 2012

The ICD-10 Spotlight: Know the codes feature that appeared in Partners in Health Update throughout 2012 was designed to communicate various coding conventions, general guidelines, and chapter-specific guidelines in ICD-10. These conventions and guidelines are rules and instructions that must be followed to classify and assign the most appropriate code. As with ICD-9, adherence to these guidelines is required under the Health Insurance Portability and Accountability Act (HIPAA). This year, we are introducing a new feature called Putting ICD-10 into Practice: Coding exercises and scenarios. Each month this feature will help you put the new guidelines and conventions you learned about last year into practice. If needed, use the ICD-10 Spotlight: Know the codes booklet for assistance with these exercises. An answer key is provided below so you can verify if your answers are correct. In addition, a list of code narratives is included to describe each ICD-10 code.
