ICD-10-PCS Character Analysis: Test Your Knowledge of Character 4 – Body Part

By

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." 

In ICD-10-PCS sections 0 through F, the fourth character defines the body part, body system, body region, or treatment site – i.e., the specific anatomical site where the procedure or service is performed. For sections G (Mental Health) and H (Substance Abuse Treatment), the fourth character defines a specific qualifier.

 

An exhaustive listing of body parts is not possible in the ICD-10-PCS root operation tables, so a Body Part Key appendix is included in ICD-10-PCS, and it is used to select the appropriate body part values for anatomic sites that are not listed in the root operation tables.

Below is an excerpt from the Body Part Key. The anatomical site listed in the left column is not provided in any of the root operation tables, so it is classified to the body part value that is listed in the right column. 

Abdominal aortic plexus

Use:

Abdominal sympathetic nerve

Abdominal esophagus

Use:

Esophagus, lower

For example, destruction of the abdominal aortic plexus would be reported using the root operation table 015, and the body part value M (Abdominal Sympathetic Nerve) would be selected to classify the abdominal aortic plexus (per the Body Part Key).

Using the ICD-10-PCS Body Part Key, fill in the blanks for each anatomic site that is listed below(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, then 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.
