Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances
        (T50)

T50.B95A is a billable diagnosis code used to specify a medical diagnosis of adverse effect of other viral vaccines, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

T50.B95A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like adverse effect of other viral vaccines. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Clinical Classification

Clinical Information

  • Rubella Vaccine

    a live attenuated virus vaccine of duck embryo or human diploid cell tissue culture origin, used for routine immunization of children and for immunization of nonpregnant adolescent and adult females of childbearing age who are unimmunized and do not have serum antibodies to rubella. children are usually immunized with measles-mumps-rubella combination vaccine. (dorland, 28th ed)

Coding Guidelines

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.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances (T50). Use the following options for the aplicable episode of care:

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

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Convert T50.B95A to ICD-9-CM

  • ICD-9-CM Code: 995.29 - Adv eff med/biol NEC/NOS
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
  • ICD-9-CM Code: E949.6 - Adv eff viral vacc NEC
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

Table of Drugs and Chemicals

The parent code T50.B95 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.

Vaccine Safety

What are vaccines?

Vaccines play an important role in keeping us healthy. They protect us from serious and sometimes deadly diseases. Vaccines are injections (shots), liquids, pills, or nasal sprays that you take to teach your body's immune system to recognize and defend against harmful germs. The germs could be viruses or bacteria.

Some types of vaccines contain germs that cause disease. But the germs have been killed or weakened enough that they won't make you sick. Some vaccines only contain a part of a germ. Other types of vaccines include instructions for your cells to make a protein of the germ.

These different vaccine types all spark an immune response, which helps your body fight off the germs. Your immune system will also remember the germ and attack it if that germ ever invades again. This protection against a certain disease is called immunity.

These diseases can be very serious. Because of this, getting immunity from a vaccine is safer than getting immunity by being sick with the disease. And for a few vaccines, getting vaccinated can actually give you a better immune response than getting the disease would.

Do vaccines cause side effects?

As with medicines, any vaccine can cause side effects. Most of the time the side effects are minor, such as a sore arm, fatigue, or mild fever. They usually go away within a few days. These common side effects are often a sign that your body is starting to build immunity against a disease.

Serious side effects from vaccines can happen, but they are very rare. These side effects could include a severe allergic reaction. Other possible side effects are different for each vaccine. Talk with your health care provider if you're concerned about your health after getting vaccinated.

Some people worry that childhood vaccines could cause autism spectrum disorder (ASD). But many scientific studies have looked at this and have found no link between vaccines and ASD.

How are vaccines tested for safety?

Every vaccine that is approved in the United States goes through extensive safety testing. It starts with testing and evaluation of the vaccine before it's approved by the Food and Drug Administration (FDA). This process can often take several years.:

  • First, the vaccine is tested in labs. Based on those tests, the FDA decides whether to test the vaccine with people.
  • Testing with people is done through clinical trials. In these trials, the vaccines are tested on volunteers. Clinical trials usually start with 20 to 100 volunteers, but eventually include thousands of volunteers.
  • The clinical trials have three phases. The trials are looking for the answer to important questions such as
    • Is the vaccine safe?
    • What dose (amount) works best?
    • How does the immune system react to it?
    • How effective is it?
  • During the process, the FDA works closely with the company who makes the vaccine to evaluate the vaccine's safety and effectiveness. If the vaccine is found to be safe and effective, it will be approved and licensed by the FDA.
  • After a vaccine is licensed, experts may consider adding it to the recommended vaccine, or immunization, schedule. This schedule is from the Centers for Disease Control and Prevention (CDC). It lists which vaccines are recommended for different groups of people. They list which age groups should get which vaccines, how many doses they need, and when they should get them.

Testing and monitoring continue after the vaccine is approved:

  • The company making the vaccines tests every batch of vaccines for quality and safety. The FDA reviews the results of these tests. It also inspects the factories where the vaccine is made. These checks help make sure the vaccines meet standards for quality and safety.
  • The FDA, CDC, and other federal agencies continue to monitor its safety, to watch for possible side effects. They have systems to track any safety issues with the vaccines.

These high safety standards and testing help to make sure that vaccines in the United States are safe. Vaccines help protect against serious, even deadly, diseases. They not only protect you, but also help to keep these diseases from spreading to others.

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.
