The External Cause of Injuries index contains codes found in Chapter 19, Injury, poisoning & certain other consequences of external causes , and Chapter 20, External causes of morbidity, of the ICD-10-CM. The codes begin with the letters S and T for Chapter 10, and V, W, X, and Y in Chapter 20.

2022 ICD-10-CM Diagnosis Code T50. 901A: Poisoning by unspecified drugs, medicaments and biological substances, accidental (unintentional), initial encounter.
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.
When applicable, place of occurrence, activity and external cause status codes are sequenced after the main external cause code(s). Regardless of the number of external cause codes assigned, there should be only one place of occurrence code, one activity code and one external cause status code assigned to an encounter.
ICD-10 code O80 for Encounter for full-term uncomplicated delivery is a medical classification as listed by WHO under the range - Pregnancy, childbirth and the puerperium .
When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug (T36-T50).
External cause codes are used to report injuries, poisonings, and other external causes. (They are also valid for diseases that have an external source and health conditions such as a heart attack that occurred while exercising.)
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.
External cause codes are never reported as primary, that is they cannot be assigned as a principal diagnosis. They never reported alone. They can be reported with any condition due to an external cause and are not limited to injuries or poisonings.
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.
Place of Occurrence, Activity, and Status Codes Used with other External Cause Code: When applicable, place of occurrence, activity and external cause status codes are sequenced after the main external cause codes. Only 1 place code, 1 activity code, and 1 status code per encounter.
Use the full range of external cause codes to completely describe the cause, the intent, the place of occurrence, and if applicable, the activity of the patient at the time of the event, and the patient's status, for all injuries, and other health conditions due to an external cause.
These codes permit the classification of environmental events, circumstances, and conditions as the cause of injury and other adverse effects, and are to be used in addition to codes that report the actual injury.
The Y codes contain two important categories: Y92 for place of occurrence of the external cause and Y93, which is an activity code. The guidelines state these codes are to be used with one another, and are only reported on the initial encounter.
E813.1 Motor vehicle traffic accident involving collision with other vehicle injuring passenger in motor vehicle other than motorcycle. Some providers already use these codes voluntarily or when required on auto insurance claims; however, many billers are unfamiliar with external cause 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. Although there is no national mandate to report them, external cause codes provide a unique opportunity to report significant detail not available in ICD-9-CM.
External cause code reporting is voluntary (but is encouraged) when ICD-10-CM is implemented. It provides the opportunity to report enhanced detail, and could streamline the process of claims submission and payment adjudication. It may also improve the process of data collection for researchers and policy makers. Physicians and coders, however, must take the time to get familiar with coding guidelines and conventions to take advantage of this opportunity provided by ICD-10 .#N#Sources:#N#Medicare Learning Network, ICN 902143, April 2013#N#Complete and Easy ICD-10-CM Coding for Chiropractic, 2nd edition, The ChiroCode Institute, 2013.#N#“ICD-10-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. Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.
In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.
