Codelist ID


Codes that indicate an episode of transverse myelitis


These codes were mapped first in snomed using the opencodelist builder. The search terms used were:

  • transverse myelitis
  • myelitis

We checked with the CPRD code finder for any other terms for inspiration too and found none.

The codes were discussed by 3 practicing doctors. A summary of this discussion is available on the github issue below.

These codes were mapped to CTV3 and rechecked. One higher level code that is now extinct that grouped transverse myelitis in with encephalitis and encephalomyelitis was excluded after discussion with the 3 clinicians.

The final codelist was signed off by the 3 clinicians indicated below.


Signed off by

  • Caroline Morton, EBM Datalab (Sept. 23, 2020)
  • Laurie Tomlinson, LSHTM (Sept. 23, 2020)
  • SinĂ©ad langan, LSHTM (Sept. 23, 2020)

This definition has been computed by taking the manually created full codelist and converting it to a list of rules that define the codelist.
