Questão jurídica principal
Whether CNA could unilaterally end its practice of reimbursing all non-medical hospital expenses once the insured started receiving an AI pension.
Decisão extraída
As a matter of principle, CNA was entitled to discontinue that gratuitous practice.
Fundamentação extraída
The insurer was not bound in perpetuity to maintain a payment practice that went beyond the statutory framework solely because the insured later received an AI pension.
