TLDRIn this ICD-10-CM coding session, Dr. Campbell focuses on Chapter 20, which covers external causes of morbidity codes (V00-Y99). These codes are crucial for injury research and prevention strategies, capturing the cause, intent, location, activity, and status of the patient at the time of the event. The session discusses general guidelines, including the use of these codes with other diagnosis codes, their placement in the secondary position, and the importance of using the appropriate external cause codes to describe the event fully. Specific categories, such as place of occurrence, activity codes, and status codes, are also explained, along with guidelines for handling cases of unknown or undetermined intent, sequelae, and terrorism-related incidents.
Takeaways
- 📚 ICD-10-CM coding focuses on Chapter 20 for external causes of morbidity, which aids in injury research and prevention strategy evaluation.
- 🔍 External cause codes capture the cause, intent (unintentional, intentional), location, activity, and status of the patient at the time of the event.
- 🚫 These codes should never be used as the principal or first-listed diagnosis; they are secondary and provide valuable data for research.
- 📈 General guidelines: Codes can be used with any diagnosis from A00.0 to T88.9 and Z00.0 to Z99.

Q & A
What is the primary purpose of ICD-10-CM external cause codes?
-The primary purpose of ICD-10-CM external cause codes is to provide data necessary for injury research and evaluation of injury prevention strategies.
What are the five things that external cause codes capture?
-External cause codes capture the cause of the injury or health condition, the intent (unintentional, intentional, or assault), the place where the event occurred, the patient's activity at the time of the event, and their status (civilian or military).
Should external cause codes be used as the principal or first-listed diagnosis?
-No, external cause codes should never be used as the principal or first-listed diagnosis; they are always placed in the second position or notes.
Are external cause codes mandatory for use?
-There is no national mandatory requirement for the use of external cause codes. They are encouraged for voluntary reporting for injury research and prevention unless mandated by a state or payer.
What is the range of codes that can be utilized with external cause codes?
-External cause codes can be utilized with any code in the range of A00.0 through T88.9 and Z00.0 to Z99.
What do the 7th character classifications for external cause codes represent?
-The 7th character classifications for external cause codes identify the stage of the condition being treated, such as initial encounters, subsequent encounters, and sequelae.
How are combination external cause codes used?
-Combination external cause codes are used to identify events in a sequence as a result of an injury, such as a fall that subsequently results in striking an object. The code should correspond to the sequence of events, regardless of which caused the most serious injury.
What is the role of place of occurrence codes (category Y92)?
-Place of occurrence codes are secondary codes used to specifically identify the location of the patient at the time of injury or other condition. They are generally assigned once at the initial encounter for treatment.
How are activity codes (category Y93) used in relation to external cause codes?
-Activity codes describe the patient's activity at the time of the injury or other health condition. They are used once at the initial encounter for treatment and do not apply to poisoning, adverse effects, misadventures, or sequelae.
What is the sequencing priority for external cause codes when multiple codes are required?
-The sequencing priority for multiple external cause codes is as follows: child and abuse codes take priority over all other external cause codes, terrorism events take priority over external cause codes except child and abuse, and cataclysmic events take priority over all external cause codes except child abuse and terrorism codes for transport accidents.
How are sequela external cause codes reported?
-Sequela external cause codes are reported with the seven-character 'S' for sequela. They should be used with any report of a late effect or sequela resulting from a previous injury.

📚 Introduction to ICD-10-CM Chapter 20: External Causes of Morbidity Codes
This paragraph introduces the focus of the session, which is on ICD-10-CM Chapter 20, covering external causes of morbidity codes (V00-Y99). These codes are essential for injury research and evaluating prevention strategies. They capture the cause, intent (unintentional, intentional, or assault), location, activity, and status of the patient at the time of the event. The paragraph emphasizes that these codes should not be used as the principal diagnosis but rather as secondary notes, unless mandated by state or payer requirements. It also mentions the voluntary nature of these codes and their value in research.
📌 General Guidelines for Using External Cause Codes
This section delves into the general guidelines for using external cause codes, including their applicability to a range of codes from 0.0.0.0 to T88.9 and Z00-Z99. It explains that these codes are primarily for injuries but can also apply to infections, diseases from external sources, and other health conditions. The paragraph discusses the 7-character classification for these codes, which includes initial encounters, subsequent encounters, and sequelae. It also outlines the process of locating external cause codes using their own alphabetical index and emphasizes that these codes should always be secondary and not used as the first listed diagnosis.
📍 Place of Occurrence, Activity, and Status Codes
This paragraph discusses the specifics of place of occurrence codes (Y92 category), activity codes (Y93 category), and status codes (Y99 category). Place of occurrence codes are used to identify the location of the patient at the time of injury and are typically assigned once at the initial encounter. Activity codes describe the patient's activity at the time of the event and are used once, while status codes indicate the work status of the person during the event. The paragraph also notes that these codes should not be used with poisoning, adverse effects, misadventures, or sequelae, and that they should be assigned in a specific sequence following the main external cause codes.
🔄 Multiple External Cause Coding Guidelines
This section addresses the guidelines for using multiple external cause codes to fully describe the cause of an injury or illness. It explains the sequencing priority for external cause codes, with certain events like cataclysmic events, terrorism, and transport accidents taking priority. The paragraph also discusses the hierarchy for assigning codes, especially in cases of child abuse and unknown or undetermined intent. It concludes with guidelines for using sequela codes for late effects of previous injuries and the conditions under which they should not be reported.
🚨 Terrorism Guidelines and External Cause Status
This paragraph focuses on the guidelines for identifying and coding terrorism-related events. It specifies that terrorism events must be identified as such by the FBI or federal government. The first listed external cause code for terrorism should be from category Y38, with additional codes for place of occurrence and multiple Y38 codes possible for multiple terrorism events. It also covers secondary effects codes for conditions occurring subsequent to the terrorist event, which should not be used for conditions due to the initial act. Lastly, it discusses the assignment of external cause status codes (Y99 category) to indicate the person's work status at the time of the event.
📖 Conclusion and Transition to Chapter 21
The final paragraph wraps up the discussion on external cause codes and transitions to the next topic, which is Chapter 21: Factors Influencing Health Status and Contact with Health Services. It briefly mentions the upcoming content, indicating a continuation of the ICD-10-CM coding guidelines series.
