The City of Boston is required by law to conduct an audit of all employees and their dependents receiving municipal health insurance. This means that active employees and retirees who are covering dependents under their health plan will be required to provide certain documentation to verify their dependents’ eligibility. Please carefully read any correspondence you receive from HMS Employer Solutions because there are specific instructions and timelines outlined in the letter. Failure to follow the instructions could result in loss of coverage for your dependents.
