The Diary Codes are "reasons for review" that may be assigned during normal working of the claims. Typically, any individual working on a claim knows when a claim needs future attention and why. The "why" is the description for the Diary Code.

Any need to review the claim can be considered a "reason for review" and entered into the Diary System. For instance "Payment Due," "Call Debtor," "Pretrial Conference," "Trial," "Missed Promised Payment," "Attorney Review," "Forwarder/Client Sending Documentation," and "Awaiting Suit Authorization" are all typical reasons for review. When the daily "to do" Diary Report is printed, entries are organized by these Diary Codes.

Collection-Master automatically "tickles" a claim to a user-defined event based on file conditions; improving the "Auto-Pilot" mode. In addition to the reasons for review, the Diary Codes may also contain document and disbursement codes that can be associated with the Diary Code. When control data is associated with a Diary Code, the actions in the control data are automatically executed when the date is reached.
