If you or your dependents are covered by more than one health plan, HMSA will work with the other health plan to make sure that your claims are paid correctly. This process is called coordination of benefits and it determines which plan is primary (i.e., the plan that applies benefits first) and which plan is secondary (i.e., applies benefits to any remaining balance).

To help coordinate your health plan benefits with your other health plan, please print this form, fill it out, and mail it to HMSA at the following address:

HMSA
MS Primacy
P.O. Box 860
Honolulu, HI 96808-0860

*An online form is also available in My Account on hmsa.com. You need to register or log in. From the Forms tab, click Coordination of Benefits.

To help prevent delays, follow the instructions on the printed or online form carefully, and complete all applicable fields.
