THE OBJECTIVE

OR

ACTION OF THE PROCEDURE

5

There is a specific definition for each one of these roots

ICD-10-PCS uses terminology that coders are not accustomed to seeing on a chart

The purpose of this training is to help the coder smoothly transition to the new root operation and their meanings

Objective of the procedure 31 Root Operations

Examples of Root Operations

Bypass

Resection

Excision

Removal

Defines the body part or specific anatomical site where the procedure was performed

This is different from character 2 which provides the general Body System

There are 34 possible body part values in each body system

Examples of Body Parts are:

Liver

Kidney

Ascending Colon

Optic Nerve

Defines the approach, or the technique used to reach the procedure site

There are seven different approach values in the Medical and Surgical sectionThrough Skin or mucous membrane

Through an orifice

External

Open Natural or Artificial Opening

Percutaneous Natural or Artificial Opening Endoscopic

Percutaneous Endoscopic

Natural or Artificial Opening with Percutaneous Endoscopic Assistance

Identified devices that remain after the procedure is completed

Remember that all codes require seven characters

The default value to indicate that NO device was involved is ZExamples of Device Values

Drainage Device

Radioactive Element

Extraluminal device

Intraluminal device

Autologous tissue substitute

Synthetic substitute

Qualifier for the code that provides additional information about a specific attribute of the procedure

These qualifiers may have a narrow application, to a specific root operation, body system or body part

Most procedures will not have an applicable qualifier. The default value for NO qualifier is a ZExamples of Qualifiers

Type of Transplant

Second site for a bypass

Diagnostic excision (biopsy)

17

It is the coder’s responsibility to determine which root operation the documentation in the medical record equates to in the PCS definitions

18

The physician is not expected to use the root terms provided in PCS code description

Nor Is the coder required to query the

physicians when the correlation between the documentation and the defined PCS term is clear.
