When coding Injuries, it is vital to remember a few rules and details about this particular section in the ICD-10-CM.
Note the following:
- Initial (first visits for the issue) visits generally require 4 secondary codes from Chapter 20.
- External cause codes use 7 characters.
- initial encounter (first time seen-with the letter A)
- subsequent encounter (anytime after the first encounter-being seen for same issue)
- Sequelae (late effect-a result of the injury or issue that has occurred later on with the letter S)
Lets say, “a patient obtained a burn from hot tap water at a daycare center while doing arts and handcrafts with the children.” This individual is being seen for the very first time. In this situation, you would code the following:
The contact with the hot tap water is = X11.XXXA
The external place of occurrence of the initial burn = Y92.210
The external initial activity code for an activity involving arts and handcrafts = Y93.D9
The initial external cause status code for a status involving a student activity Y99.8
