Health Lottery

Refers to the phenomenon whereby if you live in one postcode in the UK, the National Health Service will pay for some things, but if you live in a different postcode (sometimes even the next postcode over), the NHS will not pay for those same things.

A: Are you going to get your injury looked at by a doctor?
B: No, due to the Health Lottery that counts as cosmetic treatment for me and thus the NHS will not pay
