Update on NHS Digital’s request for addition of Systemic exertion intolerance disease (SEID) to SNOMED CT terminology system

In February 2015, a panel convened by the Institute of Medicine (IOM), now the National Academy of Medicine (NAM), published a report on ME, CFS called “Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Redefining an Illness.”[1]

The panel undertook an evidence review and formulated recommendations which had included proposals for new diagnostic criteria and the suggestion of the name “Systemic exertion intolerance disease (SEID)”, as part of a number of recommendations put forward for review and consideration by the Report’s sponsor agencies.

Five years on:

  • The CDC has not adopted the term “Systemic exertion intolerance disease (SEID)”. In preference, the CDC uses “ME/CFS” on its website clinical information pages and for its Continuing Medical Education (CME) activities.
  • The NCHS-CDC have not added the SEID term to ICD-10-CM, an adaptation of the WHO’s ICD-10, that is mandatory in the US for assigning diagnostic codes for medical billing and reimbursement.
  • The SEID term has not been added to the final update of the WHO’s international edition of ICD-10 (Version: 2019).
  • The SEID term has not been added to the SNOMED CT US Edition by its managers, the National Library of Medicine (NML), either as a new Concept code, or as a Synonym or Child term.
  • The IOM panel’s Report formed part of the literature review for the revision of the ICD-10 G93.3 legacy categories. The WHO and the ICD-11 CSAC and MSAC committees have not included the SEID term in ICD-11.
  • The IOM panel’s suggested case definition has not been subject to field testing by, or on behalf of the CDC. Several studies published since the Report’s release concluded that the proposed SEID case definition lacks reliability and specificity; discussed the unintended consequences of not specifying exclusionary illnesses; and noted the lack of acceptability to patients of the proposed case definition and proposed SEID nomenclature.

A couple of minutes on Google demonstrates that some websites providing clinical information to physicians, healthcare professionals and patients are referring to “Systemic exertion intolerance disease” as though the term had been tested, evaluated and adopted by US federal agencies — when this is not the case.

In the March 2020 issue of the ME Global Chronicle, I reported on a request submitted by NHS Digital in November 2019 for addition of the “Systemic exertion intolerance disease (SEID)” term to the SNOMED CT terminology system.

SNOMED CT is used in over 30 countries and is the recommended terminology system in the UK, US, Canada, New Zealand and Australia [2].

For NHS England, SNOMED CT UK Edition is the mandatory terminology system across all primary and secondary healthcare settings. The system is used by clinicians in electronic medical records (EMRs), at the point of care, to record findings, symptoms, diagnoses, interventions, procedures etc.

The UK Edition of SNOMED CT terminology system is managed by NHS Digital [3].

Authorized users can register to submit requests for changes or additions to the terminology system via an NHS Digital submission portal. Requests that meet criteria for potential addition to the SNOMED CT International Edition are referred on for consideration by SNOMED International’s terminology specialists.

Submission #30104 (November 30, 2019) requested addition of the term “Systemic exertion  intolerance disease” as a Synonym under the existing SNOMED CT Concept: 52702003 Chronic fatigue syndrome [4].

The request appeared to originate from within the NHS (or other authorized SNOMED CT user) as no other class of stakeholder is referenced as the original requester.

The rationale text in support of request #30104 can be read on the NHS Digital Request Submission Portal, here: http://bit.ly/39Pz4vy

After drawing attention to this request on Twitter, I was contacted in March by a senior member of SNOMED International’s team.

I was advised that request #30104 had been submitted for consideration for addition to the SNOMED CT International Edition; that the request had already been processed and pending any further changes, would be implemented in the International Edition’s July release.

(Note: If the term “Systemic exertion intolerance disease (SEID)” was approved for addition to the July 2020 International Edition, the term would then be absorbed into the various national editions when they released their next updates.)

As the IOM panel’s proposed case definition and suggested term have not undergone field testing and evaluation; as the SEID term has not been adopted by US federal agencies; and as NCHS-CDC has made no decision to assign a code for SEID in the US ICD-10-CM for medical billing and reimbursement, it would be premature to approve a request for addition to the SNOMED CT International Edition.

These concerns for the potential addition of an untested, unadopted term to the SNOMED CT system were passed back to SNOMED International’s terminology specialists for their consideration.

In early June, I was informed that the terminology team had reviewed the information provided and concluded that adding “Systemic exertion intolerance disease” as a synonym is premature; that approval of this request had been retracted and SEID would not be included in the July release.

This was further confirmed on a SNOMED CT internal production page (see last entry under heading: “Concepts to be removed completely from the Alpha release content”): https://bit.ly/2Xed60V

The July 2020 release of the International Edition was published on July 31: https://bit.ly/39HA1a2

I can confirm that the two Synonyms terms that had been added under 52702003 Chronic fatigue syndrome for the Alpha production release:

● 3902795018 – SEID – systemic exertion intolerance disease
● 3902796017 – Systemic exertion intolerance disease

have been removed for the finalised July 2020 release*.

*In the event of a request for a change or addition to SNOMED CT not being accepted there is a formal appeals process and the submitter may request a further review of the decision. SNOMED International has confirmed that NHS Digital has not appealed against the decision not to add SEID to the finalised July 2020 release.

About SNOMED CT:

Clinical classifications like ICD-10 and the SNOMED CT terminology system are complementary and serve different purposes. ICD-10 is used after the event by clinicians and coders and focuses on diagnostic coding and data recording for statistical and epidemiological analysis, reimbursement and  resource allocation.

SNOMED CT is used by clinicians in electronic medical records (EMRs), at the point of care, to record findings, symptoms, diagnoses, interventions, procedures etc.

Each clinical concept or phrase is assigned a unique SCTID code to provide a standardised, machine readable terminology for recording and sharing clinical information across multiple health care settings. SCTID codes are mapped to ICD-10 and to ICPC-2e codes for interoperability.

SNOMED CT is considered to be the most comprehensive, multilingual healthcare terminology in the world. It is used in over 30 countries and is the recommended terminology system in the UK, US, Canada, New Zealand and Australia.

SNOMED CT International Edition releases two updates a year. A number of countries maintain national editions which automatically incorporate the updated content from the core SNOMED CT International releases but may also include country specific terminology. The national editions release twice yearly updates on a staggered schedule and their current content may not reflect the changes and additions to the most recent release of the International Edition.

SNOMED CT does not regulate which concepts should or should not be used in clinical records, but makes concepts available in response to requests from stakeholders and in accordance with its editorial and content development principles [1].

Since April 2018, SNOMED CT UK Edition [2] has been the mandatory terminology system for use in NHS primary care, replacing the Read Code (CTV3) terminology system which is now retired. SNOMED CT UK Edition was scheduled for adoption across all clinical, secondary care and mental health settings from April 2020.

World Health Assembly adopts ICD-11: When will member states start using the new edition?

Post #354 Shortlink: https://wp.me/pKrrB-4Sm

On May 25, 2019, the 72nd World Health Assembly voted unanimously to adopt the ICD-11, the next edition of the International Classification of Diseases (ICD).

Endorsement won’t come into effect until January 1, 2022, which is the earliest date that member states can begin using ICD-11 for reporting data.

A stable version of the ICD-11 MMS was released in June 2018 to enable member states to begin planning for implementation. This release was replaced in April 2019 with ICD-11 MMS Version: 04/2019.

ICD-11 is an electronic classification containing over 55,000 codes and a considerably more complex product than ICD-10. It has been designed to incorporate or link with other ICD classifications, such as the International Classification of Functioning, Disability and Health (ICF), the WONCA* developed International Classification of Primary Care (ICPC), and with the SNOMED-CT and OrphaNet terminologies.

Even the earliest implementers will need several years to evaluate the new edition, determine how they will use ICD-11, complete translations, produce training and implementation materials and prepare their health systems for migration. Japan is understood to be well advanced with translations and planning.

There is no mandatory implementation date: member states will migrate to ICD-11 at their own pace and according to their countries’ needs and resources but there is an expectation that countries will start planning for transition. Some member states may need to develop clinical modifications of ICD-11 for country specific use. A few countries still use ICD-9.

Global implementation of the new edition will be a patchy and prolonged process and during the transition period, WHO will be accepting data reported using both ICD-10 and the new ICD-11 code sets until the majority of member states have transitioned to the new edition. WHO has said that the last update to ICD-10 will be Version 2019.

No member states have announced timeline projections but below is a round-up of ICD-11 transition planning activities already in progress:

NHS England

NHS England mandates the use of ICD-10 in secondary care (currently using ICD-10 Version 2015).

As a WHO Collaborating Centre and designated UK Field Trial Centre, NHS Digital has taken part in ICD-11 Field Trials.

NHS Digital has said:

No decision has been made for the implementation of ICD-11 in England, however NHS Digital plan to undertake further testing of the latest release and supporting products that will inform a future decision.

NHS Digital Delen: ICD-11 resources page

Proposed Future Additions

Over the coming months, NHS Digital would like to engage and invite all users of ICD to participate and interact with the review process.

To support this, we are proposing to add the following information to our Delen site;

  • A mechanism for questions, issues, concerns and errors relating to ICD-11 to be raised to us as the UK Field Trial Centre.
  • A high-level overview of our future plans
  • Presentations providing more information on ICD-11
  • e-Learning materials to support familiarisation with ICD-11. Topics to include post coordination / cluster coding, chapter and code structure, chapter specific changes and notes, conventions etc
  • Further testing – parallel coding in ICD-10 in real-time. If you would be interested in taking part in this please let us know by emailing icd-11@nhs.net

Until NHS England has implemented ICD-11, the mandatory classification system for use in the NHS remains ICD-10.

Since April 2018, SNOMED CT (which replaces the Read Codes/CTV3 clinical terminology) has been the mandatory terminology system for use in NHS primary care at the point of contact and forms an integral part of the electronic patient record (EPR).

SNOMED CT terminology system is already used in some secondary care settings but is planned to be implemented across all secondary care, acute care, mental health, community systems, dentistry and other systems used in direct patient care by April 2020.

SNOMED CT terminology system and clinical classifications, like ICD-10, work together to fulfil different needs:

Source: Presentation: NHS Digital: Clinical Coding for non coders – Overview of clinical coding, how ICD-10 and SNOMED CT work together, and the role of the Clinical Classifications Service.

For more information on the planning that will be required before ICD-11 can be implemented within the NHS, see BETA – Clinical Information Standards, section: ICD-11 and the new Procedure Based Classification (PBC).

Australia

Australia uses a modification of the WHO’s ICD-10, known as ICD-10-AM [1].

Australian classification standards and statistics agencies were well represented on the ICD-11 Joint Task Force, with 5 of the Joint Task Force’s 21 members representing Australia, plus co-chair (Dr James Harrison, Director, Research Centre for Injury Studies, Flinders University, Adelaide) and observer (Dr Richard Madden, Professor of Health Statistics and Director National Centre for Classification in Health, University of Sydney).

For comparison, the UK had only an observer on the Joint Task Force; the U.S. had 4 participants and an observer.

The Australian Institute of Health and Welfare (AIHW) has been conducting a review of ICD-11 to inform and assist decision-makers about the new edition and its potential for adoption in Australia, see Post: #349: Australia: Potential adoption of ICD-11: Pre-consultation for decision makers.

Canada

Canada uses a modification of the WHO’s ICD-10, known as ICD-10-CA, developed by Canadian Institute for Health Information (CIHI) [1].

CIHI is participating in the testing of ICD-11 and assessing the implications for potential implementation in Canada.

CIHI has said that no decision has been made for the implementation of ICD-11 in Canada and that they are currently working on a number of initiatives to better understand the differences between ICD-10-CA and ICD-11 to help inform the business and statistical implications of adoption.

United States

The National Center for Health Statistics (NCHS) is the federal agency responsible for the use of ICD-10 in the United States.

ICD-10 has been used in the U.S. to code and classify mortality data from death certificates since January 1999. NCHS developed a clinical modification of ICD-10 for morbidity purposes (ICD-10-CM) which replaced ICD-9-CM on October 1, 2015.

Since its initial launch, in 2007, the U.S. has maintained high level participation in the ICD-11 development process and its ongoing update and improvement:

The U.S. provided representatives from professional and scientific organisations, academics and practitioners for the ICD-11 Topic Advisory Groups (TAGs) and sub working groups. Stanford Center for Biomedical Informatics Research developed the web based iCAT Collaborative Authoring Platform on which ICD-11 was developed.

The U.S. has representatives on the ICD-11 governance committees via the WHO-FIC Network; the Medical Scientific Advisory Committee (MSAC); the Classifications and Statistics Advisory Committee (CSAC); the Mortality and Morbidity (MbRF) Reference Groups; and the Functioning and Disability Reference Group, which have oversight for the annual updating and ongoing improvement of the global ICD-11 edition.

Dr Geoffrey Reed (WHO, Geneva; Columbia University) is Senior Project Lead for the ICD-11 Mental Health chapter and a member of the MSAC; Steven Hyman, MD (former Director of the National Institute of Mental Health (NIMH) and former DSM-5 Task Force member) chaired the Topic Advisory Group for Mental Health; Michael B First, MD has served as a key external advisor to the Mental Health chapter. Harold Pincus, MD co-chaired the ICD-11 Quality and Patient Safety Topic Advisory Group.

Dr Christopher Chute (John Hopkins University) chaired the ICD-11 Revision Steering Committee, was a member of the Joint Task Force and now co-chairs the MSAC; Donna Pickett (Chief, Classifications and Public Health Data Standards, NCHS, Centers for Disease Control and Prevention, Head, Collaborating Center for the WHO-FIC in North America) co-chaired the Morbidity TAG, was a member of the Joint Task Force and is a member of the CSAC; Dr Robert Anderson (Chief, Mortality Statistics Branch Division of Vital Statistics, Centers for Disease Control and Prevention) was a member of the Joint Task Force and co-chaired the Mortality TAG; Cille Kennedy (ASPE) co-chaired the ICD-11 Functioning TAG; Sue Bowman (Senior Director of Coding Policy and Compliance, AHIMA) is a representative on the ICD-11 Morbidity Reference Group (MbRF).

Around 25 member states have modified ICD-10 for country specific use.

WHO is still formulating policies around the licensing of ICD-11 but it is understood that the intention is to limit development of national modifications.

See Presentation slides #36-38 for more information on licensing and the development of country modifications: Insights into the Next Revision: Like Texas, Everything is Bigger in ICD-11, Kathy Giannangelo, RHIA, CCS, CPHIMS, FHIMA, Texas Health Information Management Association.

It would be premature to speculate when the U.S. might be ready to migrate to ICD-11 for mortality (cause of death reporting) and whether ICD-11 will be adequate as a morbidity classification system for U.S. use or whether NCHS will need to develop a clinical modification, as it did for ICD-10.

It was put forward at the June 5-6, 2019 NCVHS meeting that the U.S. might potentially use ICD-11 unmodified if WHO were to incorporate some additional terms within the global ICD-11 edition.

NCVHS has initiated the process of planning for transition to ICD-11 at the federal level.

In February 2019, William W Stead, MD, Chair, NCVHS, sent a letter to the Secretary of Health and Human Services (HHS) recommending a simplified process for adopting future versions of ICD. The letter also recommended that HHS should invest now in an ICD-11 evaluation project and develop a plan to enable a smooth, transparent transition from ICD-10 to ICD-11 at the optimal time.

WHO-FIC Africa

WHO-FIC Africa Collaborating Centre has said:

ICD-10 is the current standard for Morbidity (cause of illness) and Mortality (cause of death (COD) coding.

The ongoing implementation and maintenance of ICD-10 for mortality and morbidity coding remain a core focus of the WHO-FIC Collaborating Centre (African region). Following the release of ICD-11 MMS in June 2018, there will be increasing focus on ICD-11 in the work plan of the collaborating centre. Inputs to the development of ICD-11 are essential to ensure that the classification meets regional needs.

WHO-FIC Africa News: WHO on the Implementation of ICD-11, November 2018:

WHO-FIC collaborators met in Pretoria (South Africa) on 7 November 2018, discussing the implications for implementing ICD-11 and ICHI. We linked up with Nenad Kostanjsek from WHO (Geneva), who shared his thoughts about the preparation for implementation of ICD-11.
