My mum was 66 when she had her accident while cycling in India (broke her pelvis and had a fronto-temporal head injury). Once she got back to the UK (which is a whole other story although the care in India was exemplary), my dad had to fight to get her any rehab at all as she was "older than 65" 
Funnily enough, once the Herald did an article about her (comparing the care in India with what she experienced when she returned) a place in the PDRU (Physically Disabled Rehabilitation Unit) miraculously suddenly opened up 
But my dad (a former medic himself and very pro the NHS - always refused to do any private work) does acknowledge that the care that the majority of Indians can access in no way compares to the tertiary care they experienced in Ajmer and then Delhi via their insurance.
