There is a big difference between a recurrence of a claim and a request for further allowance of a consequential condition.
There is a big difference between a recurrence of a claim and a request for further allowance of a consequential condition. OWCP uses the same form for both types of request. OWCP uses a CA-2A. It mystifies me why they do not have two different forms. The use of the wrong form could cause your case to be denied.
