Change-Root Operation

Explanation:

Change is defined as taking out or off a device from a body part and putting back an identical or similar device in or on the same body part without cutting or puncturing the skin or a mucous membrane. All change procedures are coded using the external approach.

The change root operation reflects only those procedures where a similar device is exchanged without making a new incision or puncture. In the change root operation, general body part values are used when the specific body part value is not in the table.
