                </disable_paymentmethod>
            </observers>
        </payment_method_is_active>
    </events>
    ...

<?php
class Vendor_Extension_Model_Observer {
    public function paymentMethodIsActive(Varien_Event_Observer $observer) {
        $method = $observer->getMethodInstance();
        
        if ($method->getCode() == 'payment_method_code') {
            
            if (condition) {
                $result = $observer->getResult();
                $result->isAvailable = false;
            }
        }
        
    }
}
