Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Other bacterial diseases
      (A30-A49)
      • Streptococcal sepsis
        (A40)

A40 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of streptococcal sepsis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Streptococcal sepsis

Non-specific codes like A40 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for streptococcal sepsis:

  • Use A40.0 for Sepsis due to streptococcus, group A - BILLABLE CODE

  • Use A40.1 for Sepsis due to streptococcus, group B - BILLABLE CODE

  • Use A40.3 for Sepsis due to Streptococcus pneumoniae - BILLABLE CODE

  • Use A40.8 for Other streptococcal sepsis - BILLABLE CODE

  • Use A40.9 for Streptococcal sepsis, unspecified - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • , if applicable, postprocedural sepsis T81.44
  • sepsis due to central venous catheter T80.211
  • streptococcal sepsis during labor O75.3
  • streptococcal sepsis following abortion or ectopic or molar pregnancy O03.37 O03.87 O04.87 O07.37 O08.82
  • streptococcal sepsis following immunization T88.0
  • streptococcal sepsis following infusion, transfusion or therapeutic injection T80.22 T80.29

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Index to Diseases and Injuries References

Sepsis

What is sepsis?

Sepsis is your body's overactive and extreme response to an infection. Sepsis is a life-threatening medical emergency. Without quick treatment, it can lead to tissue damage, organ failure, and even death.

What causes sepsis?

Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Bacterial infections are the most common cause, but other types of infections can also cause it.

The infections are often in the lungs, stomach, kidneys, or bladder. It's possible for sepsis to begin with a small cut that gets infected or with an infection that develops after surgery. Sometimes, sepsis can occur in people who didn't even know that they had an infection.

Who is at risk for sepsis?

Anyone with an infection could get sepsis. But certain people are at higher risk:

  • Adults 65 or older
  • People with chronic conditions, such as diabetes, lung disease, cancer, and kidney disease
  • People with weakened immune systems
  • Pregnant women
  • Children younger than one

What are the symptoms of sepsis?

Sepsis can cause one or more of these symptoms:

  • Rapid breathing and heart rate
  • Shortness of breath
  • Confusion or disorientation
  • Extreme pain or discomfort
  • Fever, shivering, or feeling very cold
  • Clammy or sweaty skin

It's important to get medical care right away if you think you might have sepsis or if your infection is not getting better or is getting worse.

What other problems can sepsis cause?

Severe cases of sepsis can lead to septic shock, where your blood pressure drops to a dangerous level and multiple organs can fail.

How is sepsis diagnosed?

Your health care provider may use many tools to make a diagnosis:

  • A medical history, which includes asking about your symptoms
  • A physical exam, including checking vital signs (your temperature, blood pressure, heart rate, and breathing)
  • Lab tests that check for signs of infection or organ damage
  • Imaging tests such as an x-ray or a CT scan to find the location of the infection

Many of the signs and symptoms of sepsis can also be caused by other medical conditions. This may make sepsis hard to diagnose in its early stages.

What are the treatments for sepsis?

It is very important to get treatment right away. Treatment usually includes:

  • Antibiotics
  • Maintaining blood flow to organs. This may involve getting oxygen and intravenous (IV) fluids.
  • Treating the source of the infection
  • If needed, medicines to increase blood pressure

In serious cases, you might need kidney dialysis or a breathing tube. Some people need surgery to remove tissue damaged by the infection.

Can sepsis be prevented?

To prevent sepsis, you should try to prevent getting an infection:

  • Take good care of any chronic health conditions that you have
  • Get recommended vaccines
  • Practice good hygiene, such as handwashing
  • Keep cuts clean and covered until healed

Streptococcal Infections

Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B.

Group A strep causes:

  • Strep throat - a sore, red throat. Your tonsils may be swollen and have white spots on them.
  • Scarlet fever - an illness that follows strep throat. It causes a red rash on the body.
  • Impetigo - a skin infection
  • Toxic shock syndrome
  • Cellulitis and necrotizing fasciitis (flesh-eating disease)

Group B strep can cause blood infections, pneumonia and meningitis in newborns. A screening test during pregnancy can tell if you have it. If you do, intravenous (IV) antibiotics during labor can save your baby's life. Adults can also get group B strep infections, especially if they are 65 or older or already have health problems. Strep B can cause urinary tract infections, blood infections, skin infections and pneumonia in adults.

Antibiotics are used to treat strep infections.
