Members of Tynwald will meet the UK's House of Commons Justice Committee to discuss its relationship with the Isle of Man.
Among the items due to be discussed is the ending of a 62-year-old health agreement with the UK.
The reciprocal agreement will end on 1 April. From then, residents will have to pay for non-emergency treatment when they visit the UK or get insurance.
Manx politicians campaigned for the agreement to continue.
The decision also affects tourists visiting the island. They will continue to receive free accident and emergency treatment, but will be expected to have insurance to cover the cost of any further care.
