sct crosswalk

Show all cross-terminology equivalents of a single code at once - the text equivalent of the NHS Data Migration Workbench's tri-terminology BROWSE view. Where sct transcode maps a stream of codes from one terminology to one other, sct crosswalk takes one code and shows its equivalents in every terminology.

Built on the same maps as sct transcode (see cross-terminology mapping). ICD-10 / OPCS-4 columns need a database built with sct ndjson --refsets all; without it they show (none) (CTV3 / Read v2 still work).

Usage

sct crosswalk <CODE> [--from <SYSTEM>] [--json] [--db <FILE>]

Option	Default	Description
`<CODE>`		The code to crosswalk.
`--from <SYSTEM>`	`snomed`	Terminology of `<CODE>`: `snomed`, `read2`, `ctv3`, `icd10`, `opcs4`.
`--json`	off	Emit JSON instead of human-readable text.
`--db <FILE>`	auto	SNOMED CT database.

Examples

# A SNOMED concept and all its equivalents
sct crosswalk 22298006
# 22298006  Myocardial infarction
#   read2:  G30..
#   ctv3:   X200E
#   icd10:  I219
#   opcs4:  (none)

# Start from a legacy code - resolves to SNOMED, then shows the rest
sct crosswalk X200E --from ctv3

# Machine-readable
sct crosswalk 22298006 --json
