Mark Down These External Cause Code Changes

T codes are part of Chapter 19, Injury, poisoning and certain other consequences of external causes. Here are some areas to note from the T code additions and changes:

Ecstasy poisoning additions: Watch for options to report ecstasy poisoning under new subcategory T43.64- (Poisoning by ecstasy). Your new choices are as follows:

Don’t miss: Codes in category T43- (Poisoning by, adverse effect of and underdosing of psychotropic drugs, not elsewhere classified) require a seventh character. Your choices are as follows:

  • A (Initial encounter)
  • D (Subsequent encounter)
  • S (Sequela).

Caution: Don’t forget about notes with codes. For example, T74.3 (Psychological abuse, confirmed) has new notes clarifying that the code is appropriate for “Bullying and intimidation, confirmed” and “Intimidation through social media, confirmed.”

Confirmed forced labor/sexual exploitation additions: Check for new code additions specific to confirmed forced labor and forced sexual exploitation. These codes include T74.5- (Forced sexual exploitation, confirmed) through T74.62XS (Child forced labor exploitation, confirmed, sequela). Instructions with codes from category T74- (Adult and child abuse, neglect and other maltreatment, confirmed) tell you to report an additional code, if applicable to identify any associated current injury. You should also report an additional external cause code to identify the perpetrator if known (Y07.-).

Suspected forced labor/sexual exploitation additions: You will also see new codes for suspected forced labor and forced sexual exploitation T76.5- (Forced sexual exploitation, suspected) through T76.62XS (Child forced labor exploitation, suspected, sequela).

And, don’t miss new sepsis code T81.44XX (Sepsis following a procedure).

Adopt These New Z Codes

Z codes are part of Chapter 21, Factors influencing health status and contact with health services. Z codes represent reasons for encounter, and you must report a corresponding procedure code with a Z code if the physician performs the procedure, according to ICD-10 instructions.

ICD-10 2019 will add multiple Z codes you need to be aware of including Z04.81 (Encounter for examination and observation of victim following forced sexual exploitation); Z13.3 (Encounter for screening examination for mental health and behavioral disorders); Z20.821 (Contact with and (suspected) exposure to Zika virus); and Z62.813 (Personal history of forced labor or sexual exploitation in childhood).

In addition, ICD-10 2019 will also add new Z codes for family history of lipoproteins. They are as follows:

  • Z83.43- (Family history of other disorder of lipoprotein metabolism and other lipidemias)
  • Z83.430 (Family history of elevated lipoprotein(a))
  • Z83.438 (Family history of other disorder of lipoprotein metabolism and other lipidemia).
