Codes within the T section that include the external cause do not require an additional external cause code. The Official Coding Guidelines clarified the use of external cause codes in 2014. The guidelines state: “There is no national requirement for mandatory ICD-10-CM external cause code reporting.
External cause codes were extensively reworked for ICD-10-CM. The guidelines state that these codes are most often reported secondarily to codes from nearby chapter 19, Injury, poisoning, and certain other consequences of external causes (S00-T88).
At some point in the near future, all claims for healthcare services in the United States will have to use ICD-10-CM diagnosis codes. ICD-9-CM has been the standard since 1979, but has outlived its usefulness. Because of its structure, ICD-10-CM provides better data for research and statistical analysis than ICD-9-CM.
Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
"In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.
An external cause status code is used only once, at the initial encounter for treatment. Only one code from Y99 should be recorded on a medical record.
An external cause status code should be assigned whenever an external cause code is assigned. Only one status code may be reported at the initial encounter and, just like the Activity and Place of Occurrence codes, Y99. 9 Unspecified External Cause status should not be reported if it is not stated within the record.
The use of external cause of morbidity codes is supplemental to the application of ICD- 10-CM codes. External cause of morbidity codes are never to be recorded as a principal diagnosis (first-listed in non-inpatient settings). The appropriate injury code should be sequenced before any external cause codes.
ICD-10 External Cause Codes (V00-Y99) are secondary codes that capture specific details about an injury or health event.
External cause codes may be used in any healthcare setting and with any diagnostic code. a. often used in ED, family practice, orthopedics, and ophthalmology b/c physicians specialize in circumstances or body systems frequently affected by external causes.
External Causes of Morbidity: External cause codes are intended to provide data for injury research and injury prevention strategies.
Diagnosis Codes Never to be Used as Primary Diagnosis With the adoption of ICD-10, CMS designated that certain Supplementary Classification of External Causes of Injury, Poisoning, Morbidity (E000-E999 in the ICD-9 code set) and Manifestation ICD-10 Diagnosis codes cannot be used as the primary diagnosis on claims.
4 different typesThere are 4 different types of external cause codes. Each code answers one of the following questions: How did the injury or condition happen?
"Other external cause status" code Y99. 8 includes leisure activity. Whenever patients are treated for injuries, adverse effects, or complications from procedures, coders abstract information related to the external cause of the condition.
It is important to note that in ICD-10-CM, a handful of “T” codes actually function as both a diagnosis and external cause of injury code. This applies to overdose codes (T36-T50) and toxic effects codes (T51-T65), where information about the drug or substance involved and the intent are captured a single code.
In medicine, an external cause is a reason for the existence of a medical condition which can be associated with a specific object or acute process that was caused by something outside the body.

Chiropractors may elect to add these codes to personal injury cases because they may allow third parties to obtain information from the claim form, without needing to review the medical records. Auto injury claims might use the codes that begin with the letter “V”, which are all transport accidents.
For example, V4- is used for car occupants. The next character identifies the object that was struck. The following code might be used on the claim for a passenger of a car who was injured when the car struck a pick-up truck in traffic.
There is no national requirement for mandatory external cause code reporting, but voluntary reporting is encouraged. It may be helpful to review the chapter specific guidelines for external cause codes found in section 1.C.20.
Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code. Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.
A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. birth trauma ( P10-P15.
