"
Long Covid" is what patients are calling it. But doctors and others are struggling to come up with a name for the "official" diagnosis.
One option is "
Post-COVID Syndrome", which has been criticized because some say that it's not really "post-coronavirus symptoms ", it's "continuing coronavirus symptoms". Many Long Covid patients never had the acute "flu-like" symptoms, or had minor acute symptoms, but their initial symptoms simply continued on for months, sometimes in a fluctuating pattern.
So which term is going to win?
Some of you may be familiar with the International Classification of Diseases (ICD) that is used to record "official" diagnoses in health records. A similar classification is called SNOMED, which is heavily used in the UK.
A request has now been made to include the term "Post-COVID Syndrome" in SNOMED:

(...)
UPDATE 25 September:
The day after the publication of the letter promoting "Long Covid", a new SNOMED request was made:
https://forums.phoenixrising.me/threads/long-covid-summary-of-discussions.81357/#post-2298528
And the WHO added the following update to ICD-10
(...)
SNOMED CT is a comprehensive clinical
terminology system used in many countries in parallel with ICD-10. It is used at the
point of contact with the patient to record reason for encounter, diagnosis etc.
ICD-10 is used
after the encounter for collecting data for local, national and WHO statistical analysis.
For NHS England, SNOMED CT UK Edition has been the mandatory terminology system for use in primary care since April 2018 and replaced the now retired Read Code (CTV3) primary care terminology system.
SNOMED CT is in the process of being rolled out across all NHS England secondary care settings, including mental health and dentistry.
SNOMED CT codes are mapped to ICD-10 codes and SNOMED International's terminology leads may wish to work with the WHO on development of terminology.
Three requests for addition of terminology to SNOMED CT UK Edition (potentially also for consideration for addition to the International Edition) have been submitted:
The following Concept terms have now been requested:
1
'Post COVID-19 syndrome' (requester adds "please double check with clinical bodies")
2
'Post-COVID syndrome'
3
'Long Covid' and
'Suspected long Covid'
The second of these requests was submitted by a GP,
Dr Simon Lennane - not by one of the "Long Covid" advocacy groups or one of the clinical/academic collaborations.
NHS Digital has responded to two requests for advice on coding for "Long COVID" and COVID-19 sequelae in ICD-10:

and an earlier response to a request for advice here:

According to Trish Greenhalgh, there is a committee (Professional Standards Board) working on terminology and definitions, under chair, Prof Maureen Baker CBE:
Twitter thread here, discussing development of terminology:
There is a thread on Science for ME Forum monitoring the development of terminology and definitions for post COVID-19 sequelae and "Long COVID":

The U.S.'s CDC has published this guidance for ICD-10-CM users:

This is the Revised Autumn 2020 release schedule for UK SNOMED CT:
https://hscic.kahootz.com/connect.ti/t_c_home/view?objectID=22238064
07 October 2020 (already released )
Additional UK releases are scheduled for:
04 November 2020 (20201028)
02 December 2020 (20201125)
So potentially, a term or terms and Concept code (or codes) might be added to SNOMED CT in the November or December release, if consensus is reached before the deadlines for addition of new codes.
The UK Edition of SNOMED CT is specifically for UK use. If standardised terminology and code(s) are being considered for the International Edition, these would be absorbed by the various national extensions (though national extensions may also include additional terms under Synonyms for country specific use).
