You are required to produce a Certificate of Capacity for any period you are entitled to weekly payments.
You may wish to contact your doctor to request a telehealth consultation (videoconference or teleconference consultation) for the review of your certificate if you cannot attend the doctors in person. If your doctor is unable to offer you a telehealth consultation, you can contact the insurer to discuss your concerns.
You can also discuss with your doctor and insurer your options for potentially obtaining a certificate for a period greater than 28 days. The person issuing the certificate will need to provide the special reasons for the longer period and the insurer will need to be satisfied that the certificate should be accepted.
