Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Other disorders of the nervous system
      (G89-G99)
      • Other disorders of brain
        (G93)

G93.3 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of postviral and related fatigue syndromes. 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 Postviral and related fatigue syndromes

Non-specific codes like G93.3 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 postviral and related fatigue syndromes:

  • Use G93.31 for Postviral fatigue syndrome - BILLABLE CODE

  • Use G93.32 for Myalgic encephalomyelitis/chronic fatigue syndrome - BILLABLE CODE

  • Use G93.39 for Other post infection and related fatigue syndromes - 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.


Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
  • code, if applicable, for post COVID-19 condition, unspecified (U09.9)

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.

Convert G93.3 to ICD-9-CM

  • ICD-9-CM Code: 780.79 - Malaise and fatigue NEC
    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.

Chronic Fatigue Syndrome

What is chronic fatigue syndrome (CFS)?

Chronic fatigue syndrome (CFS) is a serious, long-term illness that affects many body systems. Another name for it is myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). CFS can often make you unable to do your usual activities. Sometimes you may not even be able to get out of bed.

What causes chronic fatigue syndrome (CFS)?

The cause of CFS is unknown. There may be more than one thing that causes it. It is possible that two or more triggers might work together to cause the illness.

Who is at risk for chronic fatigue syndrome (CFS)?

Anyone can get CFS, but it is most common in people between 40 and 60 years old. Adult women have it more often that adult men. Whites are more likely than other races to get a diagnosis of CFS, but many people with CFS have not been diagnosed with it.

What are the symptoms of chronic fatigue syndrome (CFS)?

CFS symptoms can include:

  • Severe fatigue that is not improved by rest
  • Sleep problems
  • Post-exertional malaise (PEM), where your symptoms get worse after any physical or mental activity
  • Problems with thinking and concentrating
  • Pain
  • Dizziness

CFS can be unpredictable. Your symptoms may come and go. They may change over time - sometimes they might get better, and other times they may get worse.

How is chronic fatigue syndrome (CFS) diagnosed?

CFS can be difficult to diagnose. There is no specific test for CFS, and other illnesses can cause similar symptoms. Your health care provider has to rule out other diseases before making a diagnosis of CFS. He or she will do a thorough medical exam, including:

  • Asking about your medical history and your family's medical history
  • Asking about your current illness, including your symptoms. Your doctor will want to know how often you have symptoms, how bad they are, how long they have lasted, and how they affect your life.
  • A thorough physical and mental status exam
  • Blood, urine, or other tests

What are the treatments for chronic fatigue syndrome (CFS)?

There is no cure or approved treatment for CFS, but you may be able to treat or manage some of your symptoms. You, your family, and your health care provider should work together to decide on a plan. You should figure out which symptom causes the most problems and try to treat that first. For example, if sleep problems affect you the most, you might first try using good sleep habits. If those do not help, you may need to take medicines or see a sleep specialist.

Strategies such as learning new ways to manage activity can also be helpful. You need to make sure that you do not "push and crash." This can happen when you feel better, do too much, and then get worse again.

Since the process of developing a treatment plan and attending to self-care can be hard if you have CFS, it is important to have support from family members and friends.

Don't try any new treatments without talking to your health care provider. Some treatments that are promoted as cures for CFS are unproven, often costly, and could be dangerous.
