This list was examined by 2 people and the following logic applied (see github issue for more detail):\n\\- Pneumonia codes were removed as per Rothnie protocol\n\n\nAfter discussion, bronchiolitis and virus detected codes were kept in to keep in line with Rothnie protocol.\n\n", "coding_system": [ { "name": "Read codes v3", "value": 6 } ], "open_codelist_id":
