Medical claims data is a good reflection of test procedures and services provided; it’s part of the larger puzzle and serves a useful role. When aggregated, claims forms provide counts of patients, visits, and procedures by physician; account for specified disease states; and provide insight across care settings. The medical claims data from MSA – captured from over 38 million lives and more than 140 million annual claims – is an excellent supplement to data from other sources – ours and yours.
