ICD-10-PCS Character Analysis: Test Your Knowledge of Character 1

Original story posted on: April 14, 2014

While the implementation of ICD-10-CM/PCS has been delayed until at least October 2015, you shouldn’t delay your training in and mastery of ICD-10-PCS, the more complicated of the two classification systems. In the coming months, we will use the delay to test your knowledge of each of the seven characters used to build an ICD-10-PCS code.


The process of constructing codes in ICD-10-PCS is designed to be logical and consistent: individual letters and numbers called "values" are selected in sequence to occupy the seven spaces of the code, called "characters." The first character in the code determines the broad procedure category, or section, where the code is found.

The following are the 16 sections in ICD-10-PCS:

  • Administration

  • Chiropractic

  • Extracorporeal Assistance and Performance

  • Extracorporeal Therapies

  • Imaging

  • Measurement and Monitoring

  • Medical and Surgical

  • Mental Health

  • Nuclear Medicine

  • Obstetrics

  • Osteopathic

  • Other Procedures

  • Physical Rehabilitation and Diagnostic Audiology

  • Placement

  • Radiation Therapy

  • Substance Abuse Treatment.

Use the ICD-10-PCS 2014 tables and index to identify the ICD-10-PCS section where each of the following procedures is coded(the answer key is provided at the end of the test). To access the 2014 ICD-10-PCS electronic files, go online to: http://www.cms.gov/Medicare/Coding/ICD10/2014-ICD-10-PCS.html, scroll down, and download the folder titled “2014 Code Tables and Index.” When you open the folder, you will see the following file:“PCS_2014.” This PDF file is the “ICD-10-PCS 2014 Tables and Index.”
