The search terms used were:\n\n\n- transverse myelitis\n- myelitis\n\n\nWe checked with the CPRD code finder for any other terms for inspiration too and found none. \n\n\nThe codes were discussed by 3 practicing doctors. A summary of this discussion is available on the github issue below. \n\n\nThese 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. \n\n\nThe final codelist was signed off by the 3 clinicians indicated below.\n\n",
