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.
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.
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.
S72.001A is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. Short description: Fracture of unsp part of neck of right femur, init The 2021 edition of ICD-10-CM S72.001A became effective on October 1, 2020.
External causes of morbidity ICD-10-CM Code range V00-Y99V00-X58. Accidents.X71-X83. Intentional self-harm.X92-Y09. Assault.Y21-Y33. Event of undetermined intent.Y35-Y38. Legal intervention, operations of war, military operations, and terrorism.Y62-Y84. Complications of medical and surgical care.Y90-Y99.
External cause codes identify the cause of an injury or health condition, the intent (accidental or intentional), the place where the incident occurred, the activity of the patient at the time of the incident, and the patient's status (such as civilian or military).
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. Such causes are classified as "E codes" in ICD 9.
The external cause-of-injury codes are the ICD codes used to classify injury events by mechanism and intent of injury. Intent of injury categories include unintentional, homicide/assault, suicide/intentional self-harm, legal intervention or war operations, and undetermined intent.
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.)
T14.90ICD-10 Code for Injury, unspecified- T14. 90- Codify by AAPC.
External-cause definition A cause for an effect in a system that is not a constituent of that system, especially causes of personal health problems or death, such as poison, weapon wounds, or accident.
In other words, if the physician were to select a code such as S13. 4xxA Sprain of ligaments of cervical spine, initial encounter, it's also appropriate to report the external cause of the injury. The S code would act as the primary diagnosis; external cause codes can never be reported first.
How ICD-10 codes are structuredFirst three characters: General category,Fourth character (to the right of the decimal): The type of injury,Fifth character: Which finger was injured,Sixth character: Which hand was injured,Seventh character: The type of encounter (A, D, or S) as discussed above.
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. Do not assign code Y99. 9, Unspecified external cause status, if the status is not stated.
External cause of injury codes are used to define environmental events, circumstances and conditions such as the cause of injury, poisoning, and other adverse effects related to injury morbidity and mortality.
External Causes of Morbidity: External cause codes are intended to provide data for injury research and injury prevention strategies.
The guidelines are the same for burns and corrosions. Current burns (T20–T25) are classified by depth, extent, and agent (X code). Burns are classified by depth as first degree (erythema), second degree (blistering), and third degree (full-thickness involvement).
They include electricity and radiation burns. Corrosions are burns due to chemicals. The guidelines are the same for burns and corrosions.
ICD-10-CM provides greater specificity in coding injuries than ICD-9-CM. While many of the coding guidelines for injuries remain the same as ICD-9-CM, ICD-10-CM does include some new features, such as seventh characters.
