The opencodecounts R package provides easy access to yearly summaries of clinical code usage in England. The package makes NHS England’s published datasets available in R and an interactive online tool, covering SNOMED CT codes in primary care and ICD-10/OPCS-4 codes in secondary care.

You can launch the interactive Shiny app by clicking on Launch Shiny app. For work in R, all available functions (including datasets) are documented in the R Reference section.

You can install the opencodecounts package in R with:
