The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on extracorporeal photopheresis for Crohn's disease.


Crohn's disease is a chronic inflammatory disease that affects the gastrointestinal tract. It is sometimes associated with other complications such as skin rashes and arthritis. In extracorporeal photopheresis blood is removed from the patient, then the white blood cells are separated from the whole blood, treated with ultraviolet light and re-infused into the patient.

Coding recommendations

X32.7 Leucopheresis

In addition a code from category K50.- Crohn disease [regional enteritis] would be assigned.
