In England, an integrated care system (ICS) is a statutory partnership of organisations who plan, buy, and provide health and care services in their geographical area. The organisations involved include the NHS, local authorities, voluntary and charity groups, and independent care providers. The NHS Long Term Plan of January 2019 called for the whole of England to be covered by ICSs by April 2021. On 1 July 2022, ICSs replaced clinical commissioning groups in England.
