An analysis system includes a data retrieval module that retrieves claimline data for a period of time. The claimline data includes multiple billing codes and corresponding prices associated with a provider. An analysis module receives the claimline data from the data retrieval module, determines whether a changepoint exists in the billing codes in the claimline data, determines a statistical parameter of changepoints per day during the period of time, and identifies a chargemaster increase for the provider in response to the statistical parameter of changepoints exceeding a threshold. An alert module, in response to identification of a chargemaster increase, publishes an alert that a chargemaster increase has occurred. The alert includes the provider's identification, a chargemaster increase date, a claimline number, a changepoint number, the billing code identification, or a price of the billing code at the changepoint. The alert transforms a user interface displayed to a user.
