In contrast to government payers like Medicare and Medicaid, commercial payers have more diversity in their policies on issues like authorization requirements, medical necessity standards, and covered services. In addition, commercial payers have greater variation in their appeal protocols, levels, and filing deadline. HLS is familiar with all of the major payers and can tailor our appeal strategy to each individual payer. We also possess the resources to handle all levels of appeal for commercial payers and maintain timeliness of each appeal level submission.
