A significant sub-set of Long COVIDpatients have symptoms that are consistent with a diagnosis of ME/CFS:
- Reduction or impairment in ability to carry out normal daily activities, accompanied by profound fatigue;
- Post-exertional malaise (worsening of symptoms after physical, cognitive, or emotional effort);
- Unrefreshing sleep;
- And either
- Cognitive impairment; or
- Orthostatic intolerance (symptoms that worsen when a person stands upright and improve when the person lies back down).
Other common manifestations of ME/CFS include pain, failure to recover from a prior infection, and abnormal immune function.
These symptoms may occur alone or along with other manifestations common to Long COVID.
Patients who have symptoms consistent with ME/CFS should be treated as ME/CFS patients, which includes guidance on energy management (e.g. pacing) and only a slow and carefully monitored re-introduction of exercise and resumption of normal activities.
ICD-10-CM Coding for the diagnosis
Effective October 1, 2022, updates to the US ICD-10-CM will enable tracking of people with ME/CFS, including those who develop the disease following COVID. These updates are specific to the ICD-10-CM, the US version of the International Classification of Diseases.

Notice about names
The Massachusetts ME/CFS & FM Association would like to clarify the use of the various acronyms for Chronic Fatigue Syndrome (CFS), Chronic Fatigue & Immune Dysfunction Syndrome (CFIDS) and Myalgic Encephalomyelitis (ME) on this site. When we generate our own articles on the illness, we will refer to it as ME/CFS, the term now generally used in the United States. When we are reporting on someone else’s report, we will use the term they use. The National Institutes of Health (NIH) and other federal agencies, including the CDC, are currently using ME/CFS.
Massachusetts ME/CFS & FM Association changed its name in July, 2018, to reflect this consensus.
