Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Toxic effects of substances chiefly nonmedicinal as to source
      (T51-T65)
      • Toxic effect of carbon monoxide
        (T58)

T58.8X2S is a billable diagnosis code used to specify a medical diagnosis of toxic effect of carbon monoxide from other source, intentional self-harm, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T58.8X2S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like toxic effect of carbon monoxide from other source intentional self-harm. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Mental and substance use disorders; sequelaMBD034Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of carbon monoxide (T58). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Present on Admission (POA)

T58.8X2S is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Drugs and Chemicals

The parent code T58.8X2 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.

According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Carbon Monoxide Poisoning

Carbon monoxide (CO) is a gas that has no odor or color. But it is very dangerous. It can cause sudden illness and death. CO is found in combustion fumes, such as those made by cars and trucks, lanterns, stoves, gas ranges and heating systems. CO from these fumes can build up in places that don't have a good flow of fresh air. You can be poisoned by breathing them in. The most common symptoms of CO poisoning are:

  • Headache
  • Dizziness
  • Weakness
  • Nausea
  • Vomiting
  • Chest pain
  • Confusion

It is often hard to tell if someone has CO poisoning, because the symptoms may be like those of other illnesses. People who are sleeping or intoxicated can die from CO poisoning before they have symptoms. A CO detector can warn you if you have high levels of CO in your home.

Suicide

What is suicide?

Suicide is the taking of one's own life. It is a death that happens when someone harms themselves because they want to end their life. A suicide attempt is when someone harms themselves to try to end their life, but they do not die.

Suicide is a major public health problem and a leading cause of death in the United States. The effects of suicide go beyond the person who acts to take his or her life. It can also have a lasting effect on family, friends, and communities.

Who is at risk for suicide?

Suicide does not discriminate. It can touch anyone, anywhere, at any time. But there are certain factors that can contribute to the risk of suicide, including:

  • Having attempted suicide before
  • Depression and other mental health disorders
  • Alcohol or drug use disorder
  • Family history of a mental health disorder
  • Family history of an alcohol or drug use disorder
  • Family history of suicide
  • Family violence, including intimate partner violence, child abuse, or sexual abuse
  • Having guns in the home
  • Being in or having recently gotten out of prison or jail
  • Being exposed to others' suicidal behavior, such as a family member, peer, or celebrity
  • Medical illness, including chronic pain
  • Stressful life event, such as a job loss, financial problems, loss of a loved one, a breakup of a relationship, etc.
  • Being between the ages of 15 and 24 years or over age 60

What are the warning signs for suicide?

The warning signs for suicide include:

  • Talking about wanting to die or wanting to kill oneself
  • Making a plan or looking for a way to kill oneself, such as searching online
  • Buying a gun or stockpiling pills
  • Feeling empty, hopeless, trapped, or like there's no reason to live
  • Being in unbearable pain
  • Talking about being a burden to others
  • Using more alcohol or drugs
  • Acting anxious or agitated; behaving recklessly
  • Sleeping too little or too much
  • Withdrawing from family or friends or feeling isolated
  • Showing rage or talking about seeking revenge
  • Displaying extreme mood swings
  • Saying good-bye to loved ones, putting affairs in order

Some people may tell others about their suicidal thoughts. But others may try to hide them. This can make some of the signs harder to spot.

What should I do if I need help or know someone who does?

If you or someone you know has the warning signs for suicide, get help right away, especially if there is a change in behavior. If it is an emergency, dial 911. Otherwise there are five steps that you can take:

  • Ask the person if they're thinking about killing themselves.
  • Keep them safe. Find out whether they have a plan for suicide and keep them away from things that they can use to kill themselves.
  • Be there with them. Listen carefully and find out what they are thinking and feeling.
  • Help them connect to resources that can help them, such as through:
    • Calling or texting the 988 Suicide & Crisis Lifeline at 988.
    • Chatting through Lifeline Chat.
    • For veterans, reaching the Veterans Crisis Line by:
      • Calling 988 and then pressing 1.
      • Texting to 838255.
      • Chatting with them.
  • Stay connected. Staying in touch after a crisis can make a difference.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
