Why are patients coded with an external cause code?

What is a sequelae code?
Sequelae codes are used to report late effects of an injury for as long as they are present or are being treated. When determining if a sequelae code should be reported, keep in mind that a sequela, or late effect, is not the same as a healing injury.
Is there a mandatory reporting requirement for Chapter 20?
That said, there are still no national guidelines for mandatory reporting for the codes of Chapter 20: External Causes of Morbidity.

Is morbidity code a primary diagnosis?
Before we dive in, remember: external causes of morbidity codes are never to be coded as the primary or principle diagnosis.

What is the ICd 10 for head injuries?
In ICD-10-CM, injuries are grouped by body part rather than by category, so all injuries of a specific site (such as head and neck) are grouped together rather than groupings of all fractures or all open wounds.

What is initial encounter?
Initial encounter (A) is used while the patient is receiving active treatment for the injury (e.g., surgical treatment, emergency department encounter, and evaluation and continuing treatment by the same or a different physician).

Sequelae External Cause Codes
- Sequelae codes are used to report late effects of an injury for as long as they are present or are being treated. When determining if a sequelae code should be reported, keep in mind that a sequela, or late effect, is not the same as a healing injury. A healing injury should be reported with the seventh character “A” or “D” as appropriate for follow-up care.
Terrorism Guidelines
- Code category Y38, Terrorism is only reported when the cause of the stated injury is reported as such by the Federal Bureau of Investigation (FBI). If the event or cause is not reported by the FBI as terrorism, or it is suspected, it is then classified as an assault.
