How do I request review of HMSA’s MAC for a specific type of service?

Some HMSA contracts, including the Participating Physician Agreement, include a provision whereby the provider may request fee review if the provider believes HMSA’s Maximum Allowable Charge (MAC) for a specific service is not sufficient. If your contract contains this provision (generally found in section 8.4 of the contract), you may request a fee review as discussed in Fee Reviews.

How are fees determined for medical services?

HMSA takes several factors into consideration when reviewing its Schedule of Maximum Allowable Charges for the following calendar year. Some of the factors taken into account include:

  • Local economic conditions. The Consumer Price Index (CPI) for Honolulu is reviewed for a 12-month period from July 1 through June 30 and is compared to the national average for the same period. HMSA also considers the price index specifically applied to medical services and supplies.
  • Utilization increases. Utilization calculations are also done for the July through June time period for all medical services including physician services, lab and X-ray, various therapeutic services and more.

These factors, along with projected dues income and projected utilization increases associated with new benefit coverage and new technology, are considered, and fee adjustments for the coming year are determined in August and September for implementation in January of the following year.
