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.

ICD-9 Footnotes
General Equivalence Map Definitions
The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
- Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
Index of Diseases and Injuries Definitions
- And - The word "and" should be interpreted to mean either "and" or "or" when it appears in a title.
- Code also note - A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- 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.
- Type 1 Excludes Notes - 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.
- Type 2 Excludes Notes - A type 2 Excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- Includes Notes - This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- Inclusion terms - List of terms is included under some codes. These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- NEC "Not elsewhere classifiable" - This abbreviation in the Alphabetic Index represents "other specified". When a specific code is not available for a condition, the Alphabetic Index directs the coder to the "other specified” code in the Tabular List.
- NOS "Not otherwise specified" - This abbreviation is the equivalent of unspecified.
- See - The "see" instruction following a main term in the Alphabetic Index indicates that another term should be referenced. It is necessary to go to the main term referenced with the "see" note to locate the correct code.
- See Also - A "see also" instruction following a main term in the Alphabetic Index instructs that there is another main term that may also be referenced that may provide additional Alphabetic Index entries that may be useful. It is not necessary to follow the "see also" note when the original main term provides the necessary code.
- 7th Characters - Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- With - The word "with" should be interpreted to mean "associated with" or "due to" when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular List. The word "with" in the Alphabetic Index is sequenced immediately following the main term, not in alphabetical order.
