Abstract: Quantitative estimate accuracy scoring is provided. An estimate scoring engine uses estimate scoring model logic to quantitatively measure the accuracy of an estimate for healthcare services relative to actual values associated with an adjudication of a claim for the services. Scores are determined for various factors that impact estimate accuracy, and a total estimate accuracy score may be determined. A report may be generated and displayed in a user interface including information received and/or determined by the estimate scoring engine. A plurality of estimates may be evaluated, and the report may include a summary and details associated with the accuracy of a range of estimates. An accuracy rate associated with the range of estimates may be measured against the accuracy rate of other healthcare services providers, payers, and/or estimation models in an ‘apples-to-apples’ comparison. Accordingly, issues associated with estimate inaccuracies may be identified and addressed to improve estimate accuracy.
