An IPFR is a request to a health board or the Welsh Health Specialised Services Committee (WHSSC) to fund NHS healthcare for patients who fall outside the range of services and treatments that an NHS organisation routinely provides. An IPFR can cover any type of healthcare, including a specific service, treatment, medicine, device or piece of equipment. There are several hundred IPFRs every year and the majority are accepted.
