Hi Cricketics,
maybe it's best if you post this in the "Patient corner", as this section here is more for Physios discussing Physio
You are mainly interested in costs of assessment and treatment, so might get more responses in a section where other patients also read and report.

Sorry, I cannot give any advice as our health system is very different to yours.
Some shoulder injuries require immobility, others don't at all.
But if you play cricket professionally, don't you have a Doctor of Physio attached to your team? Would that not be covered by your Club membership?

Regards,
Fyzzio
